Barrel and Handguard

The 14.5-inch barrel is constructed from 4150 CrMoV steel in a government profile with a phosphate finish and a 1-in-7 twist rate. The thread pitch is 1-in-2x28, corresponding to the included GI birdcage flash hider. The carbine-length gas system pairs with a 0.750 steel micro low-profile gas block positioned beneath the handguard. The 12-inch MX10 M-Lok handguard is made from aluminum in black and keeps the handguard clear of the barrel along its full length.

Upper Receiver and Bolt Carrier Group

The upper receiver is constructed from 7075-T6 aluminum with M4 feed ramps and an anodized finish. The bolt carrier group features an 8620 alloy steel body and a 9310 alloy steel bolt head, both with a nitride finish, is compatible with 5.56, .223, .300, and .350 configurations, and is manufactured in the USA. 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 aluminum 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, 3 oz standard carbine recoil buffer, carbine recoil spring, metal end plate, and castle nut, providing the components needed to complete a stripped lower receiver. The lower receiver itself is not included.

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.
