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. – Caliber 9mm – Color Black – Barrel 6 Cold Radial Hammer Forged Melonite® 1:10 1/2×28 – Sights Hybrid Flip-Up – Upper Receiver Monolithic Aluminum Type III Hardcoat Anodized – Lower Receiver Injection Molded Glass-Filled Polymer – Gas System Roller-Delayed – Handguard Integral M-Lok® – Trigger Flat Aluminum – Muzzle Device Multi-Port Muzzle Brake – Receiver End Plate Picatinny – Charging Handle Reversible Non-Reciprocating – Safety Switch Ambidextrous – Trigger Guard Integral to Receiver – Grip AR-Pattern w/ Adaptive Grip Texture – Magazines (2) 30-Round – Weight 4 lbs 10 oz – Length 15.5
