Barrel and Upper Receiver

The 16-inch barrel is made from 4150 Chrome Moly Vanadium steel with a nitride finish and a 1-in-10 twist rate. The barrel is threaded at 1-in-2x36, matching the included 9MM A2 bird cage flash hider. The AR-15 upper receiver features M4 feed ramps and is constructed from 7075 T6 aluminum with an anodized finish.

15-Inch Freefloat Keymod Handguard

The 15-inch freefloat Keymod handguard provides Keymod interface slots along its exterior for accessory attachment. At 15 inches, the handguard does not extend past the 16-inch barrel, leaving the muzzle end of the barrel exposed beyond the handguard profile. No handguard material was provided in the spec sheet, so material details are omitted here.

9MM Bolt Carrier Group and Charging Handle

The 9MM nitride bolt carrier group is constructed from 8620 alloy steel with a nitride finish and an external extractor. This bolt carrier group is compatible with both Glock and Colt pattern magazines, providing broad magazine compatibility for the AR-9 platform. The AR-15 M4 mil-spec charging handle is included as part of the upper operating components in this kit.

Special Operations Stock and Buffer System

The Special Operations AR-15 stock is included as part of this full build kit. The buffer system consists of a mil-spec heavy-duty AR-15 6-position buffer tube and a 5.5 oz buffer. Recoil spring, end plate, and castle nut are included as canonical full build kit components. This blowback-operated AR-9 configuration uses the 5.5 oz buffer as part of its included buffer system components.
