• Users prioritizing a compact, maneuverable platform

Nitride Barrel Durability

The 4150 CrMoV barrel with nitride finish resists corrosion and wear better than standard mil-spec finishes. Nitride barrels maintain accuracy over extended shooting sessions and require less maintenance than unfinished steel. The government profile balances weight and stiffness for a 10.5-inch configuration.

KeyMod Accessory Ecosystem

The 10-inch KeyMod handguard provides multiple mounting points for tactical accessories without adding significant weight. KeyMod slots accept lights, foregrips, and rail sections for customization. The aluminum construction keeps the platform lightweight while maintaining rigidity needed for precision shooting.

KAK Brace Configuration

This kit ships with a KAK Shockwave Blade pistol arm stabilizer brace designed for single-handed shooting support. The brace does not convert the platform to an SBR and remains compliant with federal regulations as a pistol accessory. The heavy-duty pistol buffer tube accommodates the brace and carbine-length recoil spring for reliable cycling.

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