What’s Included

Forged from 7075-T6 aluminum, the upper and lower receivers are machined in-house and finished with Type III hard-coat anodizing for added surface durability. The flat-top A3 upper includes a forward assist, shell deflector, and dust cover, giving users the familiar functionality of a duty-grade AR.
The 12.5-inch 4150 CMV steel barrel is chrome-lined, threaded, and capped with a standard A2 flash hider. A 1:8 twist rate balances performance with both light and heavier 5.56 NATO bullet weights, while the carbine-length gas system is tuned for dependable cycling.
Surrounding the barrel is a free-float aluminum M-LOK handguard with a continuous Picatinny top rail, offering ample space for lights, lasers, or optics. Flip-up iron sights arrive installed, so the pistol can be zeroed immediately or paired with an optic of choice.
The KAK Shockwave Blade brace provides a stable interface without adding unnecessary weight, and the A2 pistol grip offers a familiar control point. SAFE/FIRE pictographs on the selector keep operation intuitive.
A 60-round Schmeisser S60 magazine ships with the firearm, giving the shooter extended capacity right out of the box.
