2021: AR Buttstock Rundown

[Sanch]

I’d like to upgrade the buttstocks on some ARs. I have an old M93 magpul on one gun and a newer magpul UBR on another. I never liked the USGI collapsible buffer tube, it seemed weak and I didn’t like the castle nut setup requiring a special wrench. That was a decade ago and I don’t really shoot my ARs because handgun and shotgun practice is more important but I’d like to get back to the AR and am trying to figure out what accessories to optimize starting with the buttstock.

A friend shot my UBR and commented that there’s a big gap between the buffer tube and the top of the buttstock when it’s extended. I always thought these magpul proprietary buffer tube system was way stronger and preferred but now that I look at the market, virtually everything is based around the USGI buffer tube system so maybe I underestimated that when I got into ARs 15 years ago.

Or maybe it’s just what everyone is making because of momentum and commonality.

What’s the consensus on the magpul proprietary tube systems like the old m93 and UBR? I’m guessing the weight is more a detractor than the gap on the top but maybe people hate both? I kind of liked the balance of the magpul proprietary stocks. I’d guess a light stock on a GI buffer tube would be very front heavy but maybe that’s good for swinging the gun target to target?

It just seems like the GI tube is too weak and could bend if you dropped the gun off a cliff, not that I do that, but it’s hard to break from LARPING mind. I mean, I’m not a cop or a soldier and if I’m grabbing my AR then it’s some bad times indeed and in that circumstance it does seem more valid to be worried about durability. But maybe it’s just fine and durable enough and it just looks weak. And it was old fudds back in early 2000s saying we shouldn’t run them.

[rcbusmc24]

USGI style MILSPEC receiver extensions are just fine and plenty durable. stay away from Commercial spec tubes. Every AR I have wears either a BCM stock (lighter / more compact builds)or a LMT SOPMOD stock (heavier/ DMRish builds) with the exception of my MK12mod1 which is actually equipped with a KAC M110 fixed stock, but there is a pretty good chance it is going to get a SOPMOD as well... Theoretically, I suppose the receiver extension could be a weak spot but there are other things I would be more worried about first.... To me both the UBR and the old M93's were excessively heavy, though honestly I've never really cared for any of the Magpul stock offerings.

[pastaslinger]

I am in the process of dumping all my rifle stocks and buffer assemblies because despite the comfort on some of them like the Magpul PRS stock, they are in general way too heavy for a 5.56 rifle in my opinion.

My favorite carbine stock is the B5 sopmod enhanced. It has great cheek weld, is lighter than rifle stocks but balances well, has a rotation limited QD socket, and simply looks great. I like the flat buttpad but some do not. It is not the cheapest stock however.

I used to have a Magpul SL-S but the sling swivel wasn't well designed in my opinion- it is not rotation limited and as a result it does not work well with the stock geometry. It is otherwise a very comfortable to use stock and the buttpad with forward toe is very nice.

The Magpul CTR is a great stock that isn't new, but still works well. I like it for red dot setups. It's light but relatively sturdy and has a decent sling mounting setup. The Magpul MOE is a similar geometry stock but I would go for the CTR for the sling mounting alone.

I am planning to try the Magpul SL as a replacement for the CTR but I am waiting for the color I want to come in stock. I think the problems with the SL-S sling might be better with the SL.

Vltor stocks are well regarded but I see no reason to get them over the B5 sopmod, especially when I maintain a beard.

I have not played with the BCM stocks yet but I trust Magpul furniture durability a little more than the BCM. I do like the idea of the BCM mod 0 sopmod and may buy one in the future.

[Sig_Fiend]

Get yourself a BCM Mod 0 stock, and don't worry so much.

[Malamute]

Probably not very popular, but my favorite is the A2 rifle stock. They fit me well and are solid, besides having the trap for cleaning rod and supplies.

Shooting a mid gas carbine @ 600 yards with magpul stock with the little clamping lever thing that makes the stock tighter, Id lose the image in the scope when firing from stock wobble, shooting the same scope setup on a rifle at the same range, its like shooting a 22, perfectly clear scope image, no wobble or losing the image when firing, I can spot my hits perfectly clearly. Obviously almost everyone elses mileage varies.

[theJanitor]

My fav is the SOPMOD, but now I'm running CTR's on everything, mostly because I have LAW folders on everything, and the thinner stock just makes the package a bit slimmer

[Elwin]

I'm just running MOE on everything like it's 2009. I'm sure that'll get me killed someday, but it works so far.

[rd62]

Ive been a big fan of the VLTOR Emod and run one on my middy. I was thinking of updating the CTR on my SBR to an Emod but after trying a BCM on my SPR believe I'll probably go that route instead. The BCM has the cheek weld I prefer without the beard snagging battery tube interface and at a better price point than the VLTOR.

[Bergeron]

I'm actually a fan of the M93 and of the UBR. I like the fixed-position cheekweld, although the weight is a penalty. The UBR Gen2 is supposed to be noticeably lighter in weight, but I haven't had the chance to handle a gun with one yet.

I think some of the AR furniture stuff is driven more by fashion than anything else. You can look at carbine, and based on the furniture & optics, know about when it was put together. If the stuff you have works, I don't really see a need to change. If you're building new, I can see using lighter weight components.

[Clusterfrack]

All I use anymore is the CTR on milspec tubes.

I have one rifle length lower with a Seekins 10-X stock that is like a lighter PRS.

[vcdgrips]

My Carbine is so 2008---

Standard M4 style stock on a commercial tube.

Eagle Armalite Lower/Bushmaster Pencil Barrel Upper.

Aimpoint Pro which replaced a Rev E EO-Tech when they bought them all back.

In more than a day and less than 5 years I will upgrade to something simple and light and go to a two point I suspect.

[Casual Friday]

I like the B5 Systems SOPMOD Bravo. They fit nice and tight on VLTOR A5 receiver extensions and provide just the right amount of cheek weld.

[El Cid]

My go to stock for years has been the B5 Bravo. Nothing more than it needs and I prefer the angled butt over the perpendicular one on the SOPMOD.

I am curious about the new B5 Precision Stock for my .308 or my Recce. But at $200 I’d prefer someone else vet it first. Lol! I’m also intrigued by the new Magpul PRS Lite.

Regarding tubes I have long preferred the a Vltor A5 system and used it on almost all my builds. The only other option I’ve tried and been impressed with is the Geissele Super 42 system.

I haven't seen the B5 precision stock available for a while now, but I've wanted to try it. The PRS lite looks like a great option too and fixes my main issue with the PRS- weight.

[YVK]

I recently had a lapse of judgment and tried this new wave minimalist lightweight L-shaped shit. Figured this was for a piston driven 9 mm PCC, should hold. It did, for like 3 outings.

Vltor Emod/A5 compartment door needs a zip tie to stay closed on mine. I still think LMT is the best although CTRs have been OK for me.


P.S. Courtesy of GJM, I found the name of that pos stock that broke on its own: Mission First Tactical Battlelink.

[Darth_Uno]

The Larue RAT stock is by far the tightest fitting stock I’ve ever had. Plus it stores a cleaning kit.

[Default.mp3]

I kind of liked the balance of the magpul proprietary stocks. I’d guess a light stock on a GI buffer tube would be very front heavy but maybe that’s good for swinging the gun target to target?Uh... no, front heavy is not good for transitions, you end up overshooting during transitions more due to inertia.

That being said, it seems to me that a well-balanced rifle goes less appreciated these days, with most folks chasing overall weight. There is a very strong argument to be made that a well balanced gun that is heavier than a muzzle heavy gun is usually easier to shoot, assuming reasonable values. I would put UBR 2.0s on all my guns if I wasn't lazy, not just for the durability factor, but also for the balance. However, my A5 REs paired with MOE SL stocks are more than durable enough for any of my use (I prefer the MOE SL over the CTR due to the buttpad pitch, better strength, and lack of need to fuck with the lock to keep it from wobbling, but it's pretty minor details overall); if you're throwing your shit off a cliff, there's a lot more to worry about beyond the RE breaking. But hey, if it's that big a deal, V7's got you covered:

[DDTSGM]

I don't really think there is an all around perfect stock.

I really like shooting with the A1 stock's I have on my fixed FSB rifles. I'm a lefty so I use anti-rotation surface mounted QD sockets on the Left side of the stocks. I have an A2 stock on my service rifle and it fits that purpose just fine.

1. My favorite adjustable stock is the Ti-7. The angled butt and the roll under at the toe fit me well. The cons on this stock for my purpose is that it's shoulders are just a little too wide, just a little. The Ti-7 has a rear QD socket, plus you can run the sling around the rear of the butt as well as around the tube, which can be a plus for some folks. The QD socket is NOT anti-rotation which is my main complaint.

2. The Magpul MOE SL also has a good butt angle, and the treatment at the toe of the stock is good, but not as good as the Ti-7. It's shoulders are a little narrower than the Ti-7 which is a plus for me. The QD socket is NOT anti-rotation and this stock doesn't allow for attaching the sling so it runs around the butt which is the reason it isn't my favorite.

3. The B5 Bravo's butt is just a trifle short for the way I mount my rifles, which is my major complaint. It has a rotation limited QD socket which is a big plus for me as this stock does not allow you to mount the sling around the butt. This stock also has the narrowest shoulders of my top three.

4. There's not a lot of love for the Roger's Super Stock on the forums, but I like mine just fine - the angled butt stock is good. Narrow shoulders. The QD socket is too low on the stock for my taste, but you can run the sling around the butt. I remove the goofy top sling loop thingie and get along just fine. Of course the stock's tightening feature makes it one of the most rigid adjustables out there.

5. Magpul MOE - narrow shoulders, the rear butt angle and configuration is almost identical to the Rogers, so that is a plus, major con is no QD socket. This is the loosest adjustable stock I own, even looser that a Stag Arms Gi-style.

I'm confused about where you wrote "doesn't allow for attaching the sling". Do you mean attaching the sling without using QD cups but with just loops? If so, you can absolutely do that, that's what the slots above the QD and along the toe are for. The same goes for the B5 Bravo.

[rob_s]

I am by no means an authority on the current state of AR but stocks. Like most things AR, the market has just gone insane in the years since when I did know a thing or two. A couple of things that I would think still carryover, imo...

Use a standard aluminum mil-spec receiver extension if you aren’t 200% sure what stock you want or if you are just starting out. It will make changing things around and you find what suits you much easier.
Funny thing about collapsible stocks, these days many people just wind up running them at the same length as a fixed A1 stock.
What you want are rotation LIMITED QD cups. Not freewheeling, and not zero rotation. There are, or used to be, QD cups that would allow some amount of rotation, maybe 45-degrees max, but would prevent the thing from just spinning and spinning. That’s what you want.

[M2CattleCo]

I'm just running MOE on everything like it's 2009. I'm sure that'll get me killed someday, but it works so far.

I’ve tried EVERY stock made since the original VLTOR and Magpul stocks and I am firm in my belief that the original MOE is the best stock ever, very closely followed by the M4 waffle stock.

I hate tight stocks, locking mechanisms, QD sockets that are invariably in the wrong place, short toes, sticky buttpads, facial hair ripping seams, and the worst offender of all... ‘Enhanced sloping cheekweld’.

On the subject of tubes?

There’s ‘mil-spec’, and then there’s mil-spec. If it’s not an impact extruded chunk of 7075 with rolled threads, dry lube, and all the right dimensions, it’s still a commercial tube.

[pastaslinger]

I believe Magpul argues that anti-rotation is not needed because with normal QDs the geometry of the stock itself will limit how much the QD can rotate.

The problem with that is that the sling gets caught on the top corner or the buttpad of the stock still

[That Guy]

I believe Magpul argues that anti-rotation is not needed because with normal QDs the geometry of the stock itself will limit how much the QD can rotate.


I'm so unfashionable I have a fixed Magpul carbine stock. But it does have one of those Magpul non-limited QD swivels. Magpul may feel like the anti-rotation is not needed, but they are wrong. The sling does twist itself around as the rifle is raised and lowered and you move about with it. It's not a big deal but it is mildly annoying.

[Nephrology]

I think basically all of my stocks are Magpuls (CTR, SL, SL-S, ACS-L, fixed MOE...) except for a VLTOR EMod that I have on a heavier Recce style build that wears a bipod.

To be honest they're all basically fine. The only thing I really want on some of them is the ability to store a spare CR2032 battery for my LPVOs (basically any gun with a powered optic), but can always find room in the PG too.

The only one I sort of am considering replacing is the SL-S because I am not sure I actually love the SOPMOD style cheek weld on this gun that much. That said I also don't really think it helps or hinders my shooting all that much so I haven't bothered to spend the money to replace it.

Would probably get another ACS-L but I sort of resent having to pay $11 on top of the cost of the stock just to use a QD sling mount.

[DDTSGM]

I believe Magpul argues that anti-rotation is not needed because with normal QDs the geometry of the stock itself will limit how much the QD can rotate.

I'm confused about where you wrote "doesn't allow for attaching the sling". Do you mean attaching the sling without using QD cups but with just loops? If so, you can absolutely do that, that's what the slots above the QD and along the toe are for. The same goes for the B5 Bravo.

I thought I was clear, but obviously wasn't, sorry. I prefer to have the sling come around the rear of the butt, in the middle, if that makes sense. Neither the B5 Bravo or the SL allow for that unless using a QD swivel.

Let me explain further - I run SOB B-Slings and buy them with the mash hook because I'm cheap. I generally have my wife remove the mash hook and sew on the swivel for the front attaching point. The rear of the SOB's that I purchase are sans swivels and I appreciate the option to run them around the rear of the stock.

And, yes, you are absolutely right about the SL's design limiting rotation.

Thanks.

[gato naranja]

I have not tried all of them, but so far I have yet to find an AR stock I can't use. I am probably the only vertebrate on the planet who just left the DD furniture on his M4V-whatever even after having bought a Magpul CTR to replace it.

(Low speed, high drag, and middlin' expectations.)

I would replace the DD stock simply because it's the ugliest thing I've ever seen on a receiver extension.

[Old Man Winter]

GI tube is plenty strong.

I was running LMT stocks on everything and decided to try some newer options a few years ago. Ordered a BCM MOD 0 and Magpul MOE SL. Liked both however the BCM plucked beard hair like a mofo. Now everything runs a MOE SL.

[tlong17]

A stock that doesn’t pull beard hair is the #1 requirement. All else is secondary.

[gato naranja]

I would replace the DD stock simply because it's the ugliest thing I've ever seen on a receiver extension.

Yes, yes... it looks like something the cat dragged in. But for whatever reason, I have never cared much about AR aesthetics. So it remains on the gun unless and until I get a wild hair about it.

The corollary: I actually don't mind the DD pistol grip either. Not as a piece of sculpture, but it feels okay and (for me) is an improvement over the A2 grip.

[Elwin]

I thought the MOE was fairly bad for plucking beard hair, good to know (?) there’s worse. For me the MOE grabs at the gap between the stock and the tube. Easy enough to fix, though. A few ranger bands, or tape or vet wrap or whatever, takes care of it.

[O4L]

Anyone else using a LaRue Tactical Rat Stock? I have one and I like it a lot. Although admittedly I'm not a big time operator.

I have one on the 6.5 Grendel Ultimate Upper (and lower) that I bought several years ago. I use that rifle off bipod, bag, or barricade, and it works just fine - it has a pretty straight butt, though.

I really like the LaRue receiver extensions.

BTW the RAT is on sale.

[littlejerry]

I've been using the MOE SL stock for years with no real complaints. Does what it should, doesn't get in the way.

On my A2 carry handle rifle I like using a Vltor EMod. The wider stock seems to work well with iron sights. I don't like it when using a magnified optic though.

I was very surprised when I borrowed a friend's rifle recently. His stock felt great, and I was shocked to see "FAB Defense" stamped on the side of it:
https://www.fab-defense.com/en/category-buttstocks/id-1940/ar15-m4-buttstock.html

The toe works well for bringing the rifle up and transitioning. I only shot it offhand and didn't try any long range or prone work, but I was genuinely surprised at how much "better" it felt than my normal MOE SL stock.

[mmc45414]

I'm so unfashionable I have a fixed Magpul carbine stock.

Interesting (but not surprising) that you prefer different style stocks for different type optics. I can see that being a thing.

IME which stock works best is based on individual factors including the shape of your face, and to a lesser extent body type.

[TWR]

I bought into the LMT SOPMOD’s a long time ago and most of my guns wore them. I had a few lighter guns that had CTR’s but nothing was ever as comfortable as the SOPMOD. I had a S&W 15-22 that I tried in a few SC matches and did okay with a MOE on it but when I put a B5 SOPMOD on it, I started winning. Everything just lines up better for me, they don’t pull my beard and I use WOTG slings just threading the sling into the stock so no anti or limited rotation is needed.

I’m just a hunter and shooter but the SOPMOD is on all my guns now. LMT or Colt RE’s are all I run, I saw one RE break and it was a commercial Bushmaster used by a cop that would charge his gun by slamming the butt on the rocker panel as he exited his cruiser. Yes I told him it was stupid after I fixed it for him. I rolled a 4 wheeler with an AR across the front rack once and the LMT tube stood up better than I did.

I've gone back and forth on this a lot. I do sort of feel like I prefer narrower stocks for magnified optics but this is 100% subjective. I've thought about replacing the couple stocks I have with the SOPMOD-style sloping cheekweld for this reason.

However, I'm not sure that it actually makes a significant difference with regard to performance. At the end of the day they all feel pretty usable to me.

For those of you who use the UBR - do you find it is worth the money? Considering one to replace my VLTOR EMOD. I feel like the UBR would ultimately be a better stock but not sure it's worth $200 to find out.

[RancidSumo]

Didn't read the whole thread, but I really like the MOE SL and MOE SL-K (with QD mount in the slot), depending on the size of the rifle. My BCM stock is probably the most comfortable and would be the best, but I hate the way it limits sling rotation.

It’s a solid stock, but better at what? It’s a boat anchor. If strength is your main concern, the BCM stock is where it’s at. I would take almost any quality stock over an UBR. I had one and have long since sold it.

That was the conclusion I came to. I ended up grabbing an ACS-L in black instead to get a thinner cheek weld for a lot less money.

[HeavyDuty]

Rather that start a new thread, I’ll add on to this.

I’ve had a UBR on one of my lowers for a gazillion years, I love how solid it is and how well it locks up. It works well on a SPRish build. The downside is the weight.

I recently had a chance to handle a carbine with the UBR Gen2. It seems to have most of all of the UBR goodness with quite a bit of weight reduction.

Does anyone have experience with the UBR Gen2?

[UNM1136]

Vitoria Clubfoot Emod here, on my work gun for the last 18 years, recommended by Uncle Pat. My "carbine" weighs 10 pounds with the Redi-Mag, Vltor, Tango Down Grips (vertical fore and pistol), Vtac sling, Aimpoint M3, and Surefire 6P in Vtac mount on a Larue Rail. Oh, and enough batteries to reload the aimpoint, surefire, and the TRL on my handgun.

But, this combo has done everything I have ever asked of it, from DMR like roles to room entries. Sniper/countersniper courses out to 500+, to CQB. Not perfect for any one role, but flexible enough for any of my conceivable needs.

The biggest downside is the Vtor stock doesn't fit the butt cups of the new racks in the units. The solution was to put the muzzle into the butt cup and latch the ratcheting clamp around the receiver extension. Took some dry work to get down, and a reflexive use will be wrong handed until the transition, but I am confident I can make it work.

I’ve used M16 A2 stocks, GI M4 stocks, SOPMOD stocks, the FN stock that comes on the FN15 Tac3, and the Magpul MOE, MOE-SL, CTR, and MOE fixed carbine stock. My favorite so far is the Magpul MOE SL. I think it’s got the right weight to balance most setups that aren’t geared towards being very light guns. It’s less than an ounce heavier than the CTR but I can feel that ounce. Maybe it’s just in my head. I like the sloping cheekweld, the angle of the butt pad, the rotation limited QD socket location, the adjustment lever, and how it fits tightly and doesn’t rotate or rattle because of the two springs inside. If I was counting every ounce, I’d probably go towards the Magpul CTR instead. I find the SOPMOD heavier than I like for some setups, at two ounces over the MOE SL. It might work well on a rifle that’s more front heavy since it would balance better.

I actually really like the MOE fixed carbine stock. I used one for the AR I put together for my girlfriend. It’s less than an ounce heavier than the CTR, about the same weight as the MOE-SL, and is pretty sturdy feeling. My girlfriend pretty short, though, around 5’2”. Once she has some more time on the rifle she’ll be able to say whether or not she needs something with an even shorter LOP. If she does, I’ll probably put it on one of my other guns and give her an adjustable stock. I’ve never used an A1 stock and am curious how it would compare to the fixed carbine MOE.

I put a fixed moe stock on my wife's carbine and I really like it. Enough so that I have debated switching to one. But I really do like bcm stocks

I recently had a chance to handle a carbine with the UBR Gen2. It seems to have most of all of the UBR goodness with quite a bit of weight reduction.

Does anyone have experience with the UBR Gen2?

I've got UBRG2 on a 16" 9mm PCC. It's not a lightweight gun, but it does balance well and I like both the solidity and the cheekweld. My .22 AR-15 has one of the old M93A2s on it, and I like both stocks. I'm having a lightweight 14.5 P&W built, and I'm using a PWS buffer tube and ACS-L. I'd eventually like a SPR-type 5.56, and I'd probably put a UBRG2 on that gun as well.

If anyone ever finds themselves in south-central LA and wants to really find out, let me know.

I saw a UBR G2 yesterday at a reasonable price, so I grabbed it. I still need to find my torque wrench and castle nut wrench, but I mounted it up hand tight last night. I like it.

The last straw for me was discovering it’s A5 length (it uses a spacer for carbine length buffer and spring.) I generally prefer A5 length recoil systems, I was an early adopter. I have a new buffer and spring on the way.

Best price I've seen for a repro CAR-15 stock yet: https://leadandsteel.co/product/ls-car15/

I'm still a fan of those when lightweight is needed, and/or to balance out a lightweight barrel gun. No need for ridiculous, minimalist, L-shaped stocks that'll break. The polymer CAR-15 repros are ~4-4.5oz, depending on the manufacturer since there are some variations. Basically half the weight of most typical M4 stocks (CTR, BCM Mod 0, B5, etc). Not the greatest or most ergonomic, but sufficient and simple.

The BCM Mod 0 (https://bravocompanyusa.com/bcmgunfighter-stock-mod-0-black/) is still one of my favorites. Simple, slick, robust, not too heavy, good ergos.

I have one of the original style CAR stocks on my confuser A1. It’s a 14.5” mid length with corncobs, and people at the range would do a doubletake because SBRs weren’t allowed in IL - the short barrel in front of the sight confused them, and most never noticed the longer handguard. It’s a great tossable lightweight carbine.

I've gone back and forth on this a lot. I do sort of feel like I prefer narrower stocks for magnified optics but this is 100% subjective. I've thought about replacing the couple stocks I have with the SOPMOD-style sloping cheekweld for this reason.

However, I'm not sure that it actually makes a significant difference with regard to performance. At the end of the day they all feel pretty usable to me.


I absolutely prefer narrow stocks for magnified optics. I don't like having to cant my head when behind the scope.

I have found I much prefer narrow, light weight stocks with the taller mounts I've been using (Unity 2.26" for AP Micros and EoTechs & 1.93"-2.04" LPVO). My favorites being the BCM Gunfighter Mod 0 and B5 Bravo.

I need to get one of those to replace my heavy ass Magpul PRS Gen 3.

I like the Magpul MOE SL stock with an Arisaka Stock Angle Adapter and a LimbSaver Recoil Pad for my 18 " inch barreled SPR/DMR type AR. I also prefer a Magpul K2 XL grip on my SPR/DMR type rifle, as I like the more vertical and larger hand filling grip that offers me better finger placement on the trigger for precision shooting. On my shorter RDS or LPV sighted AR carbines I like the Magpul MOE SL or the Magpul MOE SL-K stocks.

I have two that I really like; a Rogers super stock and a Magpull SL K. The Rogers has a separate lever that tightens to fit for zero wobble, it has a QD built in. The SL K is a minimalist design, it's light and has a small amount of wobble that I really don't notice. The SL K has a slot to mount a QD mount which I have done. Between the two I'm using the SL K more often than not.
