Description
The downfall of most AR-15s is the carbine gas system. Harsh recoil, brass flying forward, a bolt that slams, and malfunctions once you add a suppressor or an FRT all point to the same thing: too much gas, too fast.
We rebuild your system around an intermediate buffer system (BCM Mk2 or SOLGW A5) and test-fire it with the ammo you actually run, for the right bolt speed, softer recoil and less wear.
Buffer system parts, installation and test fire included.
Shooting suppressed and unsuppressed? See the Adjustable Gas Reworks Package.
Return shipping: flat $50, added at checkout — or free if you choose local drop-off and pickup at our Calhoun shop.
