A single-button takedown mechanism enables swift field-stripping and straightforward chamber-to-muzzle cleaning by letting the barrel-receiver assembly pivot up and off the grip frame—no tools needed. The precision-molded polymer grip frame boasts a serrated front strap and checkered backstrap for a secure, comfortable hold.

Featuring a lightweight, ventilated aluminum receiver engineered to aerospace standards and a tensioned stainless steel barrel, this platform offers exceptional durability. The 1/2"-28 threaded barrel, complete with thread protector, supports muzzle devices, while the cold hammer-forged construction delivers lasting accuracy. An ergonomic bolt stop and internal cylindrical bolt architecture provide consistent sight alignment for superior precision compared to conventional moving-slide designs.

Reliability is further enhanced by a contoured ejection port and bolt ears, ensuring smooth, round-after-round operation. Target acquisition is aided by an adjustable rear sight and a factory-installed Picatinny rail, ready for optics. An ambidextrous manual safety—convertible to left-side only—accommodates various user preferences, and the conveniently positioned push-button magazine release sits on the left side of the frame. A magazine disconnect prevents firing when the magazine is removed. Includes two 10-round magazines.
