2023年12月28日 · I also SBR'ed it and bought the ATI MP40 stock. All-in-all, with the cost of the parts, tax stamp, stock kit, etc - I've turned a $500 gun into a $1K+ gun, but it works (and looks!) significantly better now and the common issues mentioned, like the cocking handle issue, the appearance, and the trigger - are all remedied now.

2023年12月2日 · Now that I’ve got a 9mm suppressor (hopefully) nearing approval, I’ve got a serious desire for a 9mm SBR. I’d like something as compact as possible and Glock mag compatibility is a necessity. I like the looks of the B&T APC9 Pro but I’ve never seen one in person. What are the other options besides it and some variety of AR9?

2011年11月14日 · After receiving my stamps form the ATF for the suppressor and building an SBR, I spent the afternoon assembling my new SBR. Its a 5" barreled 9mm with SWR suppressor. I had assembled most of the lower awhile back. Its a Spikes Biohazard billet lower with Spikes LPK and Timney trigger. I Cerakoted the lower sniper grey.

2024年2月18日 · A 9mm can’t be tamed down to the level of their fancy-parts 5.56 guns because the PCCs use a massive bolt to retard the case until pressure is safe and then that massive bolt slams into the buffer. Again, it’s not that they are punishing to shoot, it’s that they are slower to shoot than a 5.56 gun that is also set up properly.

2017年12月19日 · The 9mm seams simple just swap springs/buffer untill you get it tuned correct. Main thing I am trying to achieve here is a short, quiet, cheap (to feed) SBR to play with in the back yard. Something the daughter will enjoy shooting.

2005年10月11日 · I own a 9mm and an SBR. The 9mm is much simpler to suppress and will cycle reliably with subsonic ammo. A suppressed 5.56 is not going to cycle with subsonic, and you will likely strike a baffle. And, IMHO the terminal ballistics of a 147 grain 9mm is nothing to write off. I have taken a hog and deer with mine. and my GF used the 9mm to take ...

2016年11月22日 · I would think so with some caveats. My Colt 6951 (semi-auto 16" flat top 9mm) upper runs fine on my Colt 614 (factory full-auto) lower, as does a Colt factory 10.5" 9mm barreled upper. You'll need a bunch of other parts, e.g., a 9mm ramped bolt, mag block. See the "Pistol Caliber Carbine" forum for details.

2017年9月6日 · The main contenders are the full SBR Colt, or an SBR MPX-k. The Colt upper would probably work just fine, too. The Colt draws me because of nostalgia and cool factor. Parts are everywhere, IF I hate it I can remove the mag block with a little work and have another SBR. The Sig MPx-K is sexy and a little different.

2024年10月5日 · I’m looking for my first 9mm can. I hope to use it on four different firearms: - Frankengun AR15/9 10” SBR (straight blowback) - Frankengun CMMG RDB AR9 8” SBR (delayed blowback) - PTR9 MP5 clone 9” SBR (delayed blowback) - MAX-11 10” SMG (open bolt, advanced primer ignition blowback)

2025年2月8日 · To get the most out of a 9mm suppressor you would need to run subsonic rounds. If you mostly shoot 115s or 124s then you may want to consider adding a ported barrel and running an SD suppressor like a Broad River Tactical CAR15-SD and an SD suppressor.
