.300 Blackout upper options

[LittleLebowski]

My heart wants Aero (http://aeroprecisionusa.com/m4e1-300-8-complete-upper.html).

but my wallet prefers DSG (https://dsgarms.com/dsgu-300-10-mcsr10-agb-a2) (cheaper than Aero with BCG). My best friend JL Bourne (http://www.amazon.com/gp/product/B00P434H98/ref=as_li_qf_sp_asin_il_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=B00P434H98&linkCode=as2&tag=ratio07-20) has the DSG and says it runs reliably and shoots accurately.

Palmetto (http://palmettostatearmory.com/index.php/psa-8-5-300-aac-1-8-7-keymod-nitride-upper-no-bcg-or-charging-handle.html) doesn't seem worth the savings over Aero nor the price increase over DSG.

Rock River is on crack if they think that this is a sane price (https://www.rockriverarms.com/index.cfm?fuseaction=category.display&category_id=674).

We have three 9 inch AAC uppers, and like them.

Way too expensive (http://www.brownells.com/rifle-parts/receiver-parts/receivers/upper-receivers/ar-15-m16-upper-receivers-prod54419.aspx) for a dirty poor person like me :D

Staring real hard at the Aero and a BCM BCG.

What's the word on the Aero uppers? My 300blk accuracy thread has gone nowhere, so I'm still swimming through the sea of online research. I was all but set on buying a 16" Noveske barrel and putting it in a BCM upper I have, but the Aero upper is only $50 more. I have spare BCG's and charging handles already, so the $450 Noveske pill is hard to swallow vs.the $500 Aero upper, but I can't find much about them in terms of proven or expected accuracy or long-term reliability.

I would do the DSG over the Aero unless you want a specific hand guard. I'm fond of aeros uppers and lowers but I don't know how many of their other parts they actually make.

Anecdotally, the word is that they are tops just like their lowers. I need to research optimal barrel twist, barrel construction, and rail options before making an impulse informed purchase.

It has been a while since I've seen a 9" AAC upper in stock anywhere. Looks like AAC is finally starting to get their products flowing again though, so perhaps we'll see some of these uppers soon.

It appears that the BCM KMR in .300 Blackout is coming soon...might be worth waiting for. BCM recently posted a late October ETA with 9", 12.5", and 16" uppers. If they're priced like their 5.56mm KMR line it should be reasonable. The new aluminum KMR rails weigh a touch more but the price has dropped.

Here's Pat Rogers BCM 9" KMR-8A 300BLK...

I've been resisting the .300 Blackout rabbit hole for a while now, but a friend's AAC upper has got me interested. It'll need a can though...

I've got the twist info down. 1:7 is where the industry is heading as a whole, no matter the barrel length. I even read a blurb from AAC designers that when they SAAMI spec'd the round they listed 1:8 twist, but wished they would have put 1:7. As a matter of fact, all AAC 300blk barrels are now 1:7, and they no longer offer 1:8.

As far as gas system, anything less than 16" needs pistol, but 16 can work with either pistol or carbine. That said, it seems that the consensus is that pistol length in a 16", like 1:7 twist, seems to offer the best reliability across the huge range of bullet weights for both sub and supersonic ammo offerings. While AAC does still offer 16" carbine gas guns, most others including Noveske have moved to pistol.

Aside from always buying CHF CL barrels in the past, I got nothing on barrel construction. Anyway, that's what I've come up with so far.

It just hit me the other day.....here I have this 7.62 Saker and no .300 :(

I wish I'd seen this before buying an Omega on my own. Wonder if they'll sell it to me without the can?

Dammit. I may have to get one of these now since Impact has them back in stock and priced right. I looked at them last week after watching Twang N' Bang's review, but the only places that I could find in stock were $350.

So, after some more searching, I'm convinced AeroP gets their barrels from Ballistic Advantage, which seems to be a good thing. Specs are identical, down to the ounce, profile is the same, and so are the markings sans company logos. I can't find a bad word about BA barrels.

Not a 300blk, but my 5.56 Ballistic Advantage 14.0" Hanson barrel has been a great performer so far. I wouldn't hesitate buying a BA 300blk barrel.

The link I posted above with the Aero upper states on their site is a BA bbl. I'm trying to find a reason not to spend the money. Not sure how long I can hold out.

Thanks for the info, I wish they still made the Hanson profile barrels in longer lengths. Seems they only offer them in 8.3 and 10.3 now. That's a shame, because it looks like exactly what I'm wanting. Oh well.

Knowing that Aero and BA Modern Series barrels are one in the same, I may just pick up a 16" BA direct since they offer one with a pinned low pro gas block for $220 while Aero's 16" offering is $210 without a gas block. Was thinking about buying the Aero complete upper that LL is referencing, but I already have a 12" Centurion C4 rail laying around. I could buy the BA barrel for $220 and pick up an Aero assembled upper ($79 (http://aeroprecisionusa.com/ar15-assembled-upper-receiver.html)) and put together an upper for $300 plus parts I already have.

I'm still hung up on the accuracy thing, but $220 is really tempting vs the $450 Noveske barrel that may or may not be exponentially better. Better, I'm sure, but $230 better? I'm not exactly looking to pair the Noveske with a MUR or Gen3 upper anyway. I dunno.

Yeah, that's the first place I read it, so I decided to look at the rest of their barrel offerings. I typically read specs and pass on company marketing descriptions anyway, but I was also having a "couldn't see the forest for the trees" moment none the less.

Thanks for the link.

Weapon Outfitters carries a lot of BA / Aero products, FYI.

Aero bought BA last year, so it would make sense that Aero is using them as their barrel vendor.

If you're not in a hurry for the barrel, sign up for the BA newsletter. Every week they have a "Barrel of the Week" which drops the price from retail down to distributor pricing.

My 5.56 14.5" Modern series displays similar accuracy potential as my Rainier Arms 5.56 14.5" Mountain series. I don't shoot my rifle enough to have really rung it out, but I'm happy enough after 600 rounds or so that I won't be replacing it.

[StraitR]

I guess since I've been on Aero's webpage all day they've tracked me for marketing purposes. Anyway, while reading on another site I had an Aero ad where they're offering a 10% off coupon, so I thought I'd share.

I'm pretty down on the 300 wtf, but even I'd buy one of those if I already owned a .30 cal can.

I see this line of thought/thread as an excuse for me to have another AR. Also, I've got the can. I've got stripped lowers. I live in an area where .300 makes perfect sense for deer hunting and I seriously do hunt in areas where suppressed shooting is an actual, tangible benefit for the hunter.

LL do you have a sbr or pistol lower?

I appreciate the offer but a certain SME of ours has repeatedly told me to go to his house, have his wife open his safe, and grab one of his .300s. Because....the first taste is free, ya know :D

[JSGlock34]

As a very satisfied SR15 owner, I can't help but salivate over the KAC SR30 offerings. The SR30 DSR is particularly appealing, but at KAC prices, not the .300 BO gateway upper I'm looking for. Still, I can dream...

All of the upperrs here are built with Aero Precision parts. Their rail is decent as well but not free float. I have gotten good velocity with the 10.5 upper I got from them.

[rob_s]

While quite a bit more expensive, the Remington/AAC Micro 7 in 300 BLK is pretty sweet too.

It looks like Ruger, and possibly. moss erg, are also making 300wtf bolt-actions, and the Ruger seems to retail for about $400. Not sure if the Mossberg is a real thing yet or not, but it's supposed to feed from AR mags (something I've never seen work out well on manual-action guns, but maybe they got it sorted here)
