• Those wanting a lightweight, maneuverable AR-15 configuration
• Enthusiasts prioritizing reliable components without full rifle length

Freefloat Handguard Design

The aircraft-grade aluminum handguard uses freefloat technology, meaning it doesn't contact the barrel. This design reduces harmonics and improves accuracy potential compared to standard handguards. The M-Lok mounting system provides a clean platform for adding optics, lights, or other tactical accessories without unnecessary weight. The handguard remains free of sharp edges and offers a comfortable grip profile for extended shooting sessions.

Carbine-Length Gas System Performance

This build uses a carbine-length gas system paired with the 14.5-inch barrel, a proven combination for reliable cycling in a compact package. The 0.750 gas block integrates cleanly with the freefloat design. The 9310 alloy steel bolt carrier with nitride finish handles the gas cycling smoothly while resisting wear and corrosion over time.

KAK BLADE Shockwave Brace Configuration

The KAK BLADE Shockwave brace in black provides a stable platform for pistol operation. This brace design offers improved ergonomics and control compared to standard buffer tube designs. The brace ships as part of this kit, allowing you to complete your build with a fully functional pistol configuration. The aluminum buffer tube keeps overall weight down while maintaining durability.

1:7 Twist Rate Versatility

The 1:7 barrel twist stabilizes a wide range of 5.56 NATO ammunition weights, from lighter 55-grain rounds to heavier match-grade loads. This twist rate works well for both plinking and precision shooting without over-stabilizing lighter projectiles. The 4150 CrMoV material provides barrel longevity and consistent accuracy across extended shooting sessions.

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