Designed to deliver exceptional shooting stability in a portable package, the Kuna houses a roller-delay operating system that dramatically reduces felt recoil and enhances control. Chambered in 9mm, it features a 6" threaded barrel with a muzzle brake, hybrid flip-up sights, and a 30-round translucent magazine with metal feed lips for reliable operation. Fully ambidextrous controls ensure seamless engagement for any shooter, while the non-reciprocating charging handle keeps handling smooth and unobstructed. The integrated Picatinny rail end plate allows easy attachment of stabilizing braces for added support.
