Details

The Precision Defense 9mm Bolt Carrier Group is designed specifically for blowback AR-15 pistol caliber carbines. Because of the blowback system, no rotating locking lugs or gas key is necessary like a traditional AR-15 weapon system. What keeps this bolt closed is simply the pressure of the recoil spring and the weight of the bolt is what keeps it closed long enough for the bullet to leave the barrel. The body of this 9mm BCG is machined from 8620 steel with a salt bath Nitride finish for its slick and durable properties. The bolt face itself is magnetic particle inspected and the extractor is machined from S7 tool steel. It also features something that looks like a gas key and it basically is except its sole purpose is to serve as an indexing point for the charging handle. It is however machined from a billet of steel and still has staked screws to ensure it stays in place. The Precision Defense 9mm Bolt is an affordable and reliable option for building a 9mm AR and is compatible with Colt and Glock magazines.

Features:
  • 9mm compatible with Colt and Glock magazines
  • Salt Bath Nitride finish
  • 8620 steel carrier
  • Magnetic particle inspected
  • S7 tool steel extractor
  • Billet gas key with staked screws

Got this to jump start a PCC build idea ive had an itch for, the build is a spikes tactical upper & lower (trigger assembly as well) for Glock mags,FTM barrel & buffer parts, this BCG had no reviews a few months ago when i bought it, finally completed the build, ran a Glock big stick in it with federal 124gr fmj, ran 2 mag dumps back to back, and no issues with first 200 rounds.

GET IT!

Just finished my AR9 build. Used this BCG in combination with a mil-spec upper, 5" FTM barrel, mil-spec lower with colt conversion block and ASC style mags. Also used a JP heavy buffer spring, FTM 9mm heavy buffer and Eotech XPS. This combo cycled flawlessly during its first 200 rounds. Both my buddies were droolin...THIS THING IS AWESOME!

No Issues

Working without issue with ASC colt style mags, put a couple hundred rounds in with it so far and running great!
