Angstadt Arms 9mm AR-15 Bolt Carrier Group

Features

1. 8620 Alloy Steel Construction — Machined from heat-treated 8620 alloy steel for the strength and wear resistance required of a hard-use AR9 blowback carrier.
2. QPQ Black Nitride Finish — Salt-bath nitride treatment delivers a slick, corrosion-resistant surface that runs cleaner with less lubrication and wipes down easily after range sessions.
3. Glock And Colt Magazine Compatible — Ramped bolt face feeds reliably from both GLOCK and Colt-pattern 9mm AR-15 magazines with no modification required.
4. Removable Tungsten Weight — Rear weight can be removed to clear room for a Law Tactical folding stock adapter, Maxim roller-delayed buffer, or JP silent capture spring.
5. Standard AR-15 Hammer Compatible — Drops straight into a standard mil-spec lower without needing a dedicated 9mm hammer or trigger group.
6. M16 Auto Sear Cut — Full-auto profile carrier provides added mass and proper sear engagement geometry for registered host platforms.
7. Blowback Operation — Purpose-built for direct blowback AR9 uppers running 9x19mm in pistol, SBR, or carbine configurations.
8. Drop-In AR-15 Fitment — Designed to work in standard AR-15 upper receivers, making it an easy upgrade or replacement for an existing 9mm build.
