Compact Firearm Design

The 10.5-inch barrel paired with the Shockwave Blade brace creates a truly compact shooting platform. This configuration delivers excellent maneuverability in tight spaces while maintaining the reliability of the AR-15 platform. The barrel length and gas system are optimized to cycle 5.56 NATO ammunition reliably without excessive recoil or noise. Total weight comes in at 72.4 ounces, making this a lightweight option for extended handling.

Quality Component Selection

This kit uses proven materials throughout. The 4150 Chrome Moly Vanadium barrel with Nitride finish resists corrosion while maintaining consistent accuracy. The 7075-T6 aluminum upper receiver provides rigidity, and the 9310 alloy steel bolt carrier group ensures reliability under repeated cycling. The M4 feed ramp design guarantees smooth feeding across ammunition types. KeyMod mounting on the 10-inch handguard gives you flexibility for lights, grips, and other accessories without the weight of full Picatinny rail systems.

Drop-In Trigger Ready Configuration

The kit ships with an AR-15 Lite lower parts kit, meaning you have full control over your trigger selection. Install any drop-in trigger that fits standard AR-15 lower receivers. This approach lets you customize the trigger pull weight and reset characteristics to match your shooting style and intended use.

Carbine Gas System Efficiency

The carbine length gas tube with low-profile gas block keeps the overall profile clean while maintaining reliable cycling. Carbine length systems are proven across millions of AR-15 platforms and deliver the balance between dwell time and recoil management that most shooters prefer. The standard 3 oz carbine buffer absorbs recoil consistently across different ammunition weights.

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 kit.
