Barrel and Handguard

The 5-inch BC-9 barrel is constructed from 4150 CrMoV steel in a slim profile with a phosphate finish and a 1-in-10 twist rate. The thread pitch is 1-in-2x36, corresponding to the included Recoil Technologies 9MM flash can. The freefloat M-Lok handguard is made from aircraft-grade aluminum in black and keeps the handguard clear of the barrel along its full length. This kit is blowback-operated and does not use a traditional gas system.

Upper Receiver and Bolt Carrier Group

The upper receiver is constructed from 7075-T6 aluminum with M4 feed ramps and an anodized finish. The 9MM bolt carrier group is made from 8620 alloy steel with a nitride finish. The included AR-15 M4 mil-spec charging handle pairs directly with the upper receiver and bolt carrier group.

SBR Ready Configuration

This kit is configured as SBR Ready and ships without a brace, allowing the buyer to select their own preferred brace or configuration. The mil-spec heavy-duty 6-position buffer tube and lower components are included to support a complete lower build. The final configuration is dependent on the brace selected separately by the buyer.

Lower Components

This kit includes a lower parts kit, 6 oz 9MM carbine buffer, recoil spring, mil-spec end plate, and castle nut, providing the components needed to complete a stripped lower receiver. The lower receiver itself is not included. This kit is blowback-operated and does not use a traditional gas system.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Ships without a brace. Do not attach a stock unless compliant with applicable laws. Lower receiver not included.
