Compact Carbine Configuration

This 10.5-inch setup delivers the handling characteristics of a true carbine while maintaining the reliability of a full-power 5.56 NATO platform. The carbine-length gas system cycles efficiently with standard ammunition, and the freefloat design isolates the barrel from handguard pressure for consistent shot placement. The Gauntlet Arms brace provides a stable shooting platform while keeping overall length compact for vehicle storage or close-quarters work.

Keymod Ecosystem and Accessory Compatibility

The freefloat Keymod handguard opens up extensive mounting options for lights, vertical grips, rail sections, and other tactical accessories. Keymod slots run along the handguard surface, allowing quick-detach mounting without permanent modifications. This modular approach lets you customize your setup based on intended use without replacing the handguard itself.

Davidson Defense Quality and Nitride Finishing

The bolt carrier group uses 9310 alloy steel with nitride finishing, a proven combination for durability and corrosion resistance. The 7075-T6 aluminum upper receiver is hard-anodized for protection against wear and environmental exposure. These materials and finishes are standard across quality AR-15 builds and provide reliable performance across thousands of rounds.

This full build kit includes the upper assembly, bolt carrier group, charging handle, lower parts kit, buffer tube, buffer, recoil spring, end plate, and castle nut. The lower receiver is not included and must be sourced separately. You'll also need to select your own stock or brace configuration for the lower receiver unless you're using the included Gauntlet Arms brace as your setup.
