Compact 5.56 Pistol Configuration

The 10.5-inch barrel length strikes a balance between maneuverability and velocity retention in a pistol form factor. The carbine-length gas system is tuned specifically for short barrels, ensuring consistent cycling without excessive wear. This configuration delivers the ballistic performance of 5.56 NATO in a package that's significantly more compact than a rifle-length upper, making it ideal for close-quarters environments and tactical applications where space is limited.

Mil-Spec Build Quality with USA Manufacturing

This kit prioritizes reliability through proven mil-spec components and domestic manufacturing. The bolt carrier group is made in the USA from 9310 alloy steel with nitride finish, meeting military specifications for durability and performance. The complete lower parts kit includes all internal trigger group components, hammer assembly, disconnector, and selector mechanisms needed to complete a stripped lower receiver. The recoil spring is also USA-manufactured, ensuring consistent spring rates and longevity.

KeyMod Mounting Ecosystem

The 10-inch KeyMod aluminum handguard provides multiple mounting points for tactical accessories without adding unnecessary weight. KeyMod slots run along the sides and bottom of the handguard, allowing you to attach vertical grips, lights, lasers, or other rail-mounted gear. The 6061-T6 aluminum construction keeps the handguard lightweight while maintaining rigidity under load.

Gauntlet Arms Stabilizing Brace Integration

The Gauntlet Arms polymer brace is designed to improve control and stability during shooting. The brace attaches to the heavy-duty pistol buffer tube and provides a contact point for your arm or shoulder, enhancing accuracy and reducing felt recoil. The polymer construction keeps weight down while delivering the structural support needed for consistent shot placement in rapid-fire scenarios.

Lower receiver not included. BCG and charging handle are included. Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws.
