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 included Strike Industries FSA folding brace is attached to the integrated Picatinny rail end plate further enhancing shooting stability. - Caliber 9mm - Color Black - Barrel 6 Cold Radial Hammer Forged Melonite� 1:10 1/2x28 - 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� - Pistol Brace Strike Industries FSA - 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 5 lbs 5 oz - Length 15.5-24.5
