I set up a 9mm AR a few years ago and worked through getting it as well tuned and smooth shooting as you can get a blow back 9mm AR. It’s very smooth shooting and works reliably with every ammo type I’ve fed it from 115-147 gr. The KynShot hydraulic buffer helped smooth it out a lot and I tried multiple spring weights to find the one that was best. Uses Cold SMG mags and has last round bolt hold open.
I’m just selling it because I decided to buy an MP5 clone.
Since I set it up as an SBR I’m keeping the lower to repurpose and selling a full package to turn a standard AR lower into a reliable and smooth shooting 9mm.
-10.5” New Frontier Armory 9mm Barrel
-New Frontier Armory 9mm BCG
- Slick side AR upper (9mm ARs don’t use forward assist)
- 9” MLOK handguard
- Ambi charging handle
- Mag block for Colt pattern SMG mags. Works with standard AR lower and has last round bolt hold open.
- 5 Qty 32 round Colt pattern SMG mags
- KynSHOT RB5007 hydraulic buffer
- JP smooth polished + power buffer spring.
-9mm muzzle brake and A2 flash hider
- Sig Romeo 5 red dot zeroed at 25 yards
Full package priced to sell: $500 shipped with red dot, $400 without red dot.
I also have a second upper set up with a 4.5” barrel with a 3 lug adapter and a 9” YHM quad rail handguard with Magpul forward grip. I’ll include a KVP 9mm buffer weight and buffer spring with that one. One of the pictures shows it with a Ti Rant 9 mounted to show how it looks with a suppressor mounted. $100 shipped for that upper, BCG not included.
