Angstadt Arms 9mm AR-15 Carbine Buffer Assembly

Features

1. 5.4 oz Heavy Buffer Weight — Purpose-built mass tames the aggressive bolt velocity of blowback 9mm AR-15 platforms for smoother, softer cycling.
2. Complete Three-Piece Kit — Includes the 9mm carbine buffer, dedicated buffer spacer, and carbine buffer spring — everything needed to run a 9mm AR.
3. Glock and Colt Magazine Compatibility — Works in both GLOCK-pattern and Colt-pattern 9mm AR-15/AR9 lower receivers without modification.
4. Dedicated 0.75" Buffer Spacer — Limits bolt carrier rearward travel to prevent over-travel and protect the rear of the receiver extension.
5. 3.25" Buffer Length — Drops into any standard mil-spec carbine receiver extension for a true bolt-in upgrade.
6. Carbine Buffer Spring Included — Tuned spring rate paired to the 5.4 oz buffer delivers consistent lockup and reliable feeding.
7. Orange Polymer Bumper — High-visibility impact bumper cushions the strike against the rear of the extension and absorbs felt recoil.
8. AR9 and PCC Ready — Engineered for pistol-caliber carbines running 9x19mm in blowback configurations, including competition and home-defense builds.
9. Made in the USA — Manufactured by Angstadt Arms, a leader in dedicated 9mm AR platforms and components.
