The big 10.5"-12.5" general purpose pistol/SBR thread

Assembled the lower last night and mocked up the complete upper, I'll be going with a 9mm specific upper when it gets here:


QC10 10.5" 9mm barrel
Unknown HG from arfcom EE
Stern Defense bolt
Aero lower with CMMG guts and either a PSA or ALG FCG
SBA3(?) brace and PWS H3 buffer
Magpul grip (maybe a MOE SL?)

Stripped 9mm upper and a 9mm birdcage are ordered, just waiting on them to arrive.

I started fitting the one of the Endomag conversions last night but I don't have a warm, fuzzy about it yet but that's for another thread.

11.5 "firearm." Sionics reduced gas port barrel on Sionics A5 lower. Specwar 762 not pictured

Yeah, purely ringing steel. Most Run n Gun matches have a longish stage and get out to 400-600 yards depending on the venue. If I build up a 12.5" gun I'd like for it to be useful in those matches. I'll keep a 16" rifle for DMR matches

I’d take a look at specific barrels for that - Hodge or Triarc probably. The latter has several reports of pushing rounds faster than standard uppers of comparable barrel length and while I don’t know if I’ve seen that from Hodge, I wouldn’t be surprised based on all of the magic voodoo that supposedly goes into those.

I just got a MK18 upper mostly because of the PDW thread. A Triarc 12.5 mid may be my next one.

Daniel Defense Mk18
DDM4 9" rail
Aimpoint H2 on Scalarworks Mount. I have a Vortex 3x Mag that fits nicely behind the RDS.

Streamlight RM1 tucked up snugly in the 1 O'Clock position using an American Defense Manufacturing offset scout mount
Geissele SSA
BCM grip and AFG
SBA3 with LAW Gen 3 folder

between the lighter rail, Streamlight and LAW, it balances out nicely....right at the mag well.

Do you know the oal of that with the stock folded?

Yes sir, just measured to double check.

20" on the dot with the DD birdcage. Barely squeezes into a VertX Gamut (20" backpack) as detailed in the PDW thread.

Add or subtract appropriately for your muzzle device of choice. This one will be getting a YHM QD flash hider when the Form 4 paperwork comes back.



ETA: The extremely tight fit of the light allows it to slide into the laptop compartment of the VertX a-ok, no problem. It's so tight that it can't be mounted further forward because of interference with the front sight.

When the YHM Turbo K is released to me, I might put a Haley Strategic Thorntail scout mount on there to get it up further. IDK. It works really well right now.

Would you mind talking a little bit about your storage setup there? Is that bolt locked to the rear with chamber flag in? So upon deployment you rip out the chamber flag and either pull the charging handle or slap the bolt release?

That's a Brownells Safe-Port. It has a spring that ejects the device when you charge the gun.

I especially like it for backcountry use because my buddies can easily see that the gun is safe.
