Shark Coast Tactical Penny Features The Shark Coast Tactical Penny is built around a chrome moly steel barrel measuring 16 inches finished in a black Melonite coating that adds corrosion resistance and surface hardness beyond what a bare steel barrel would offer. A 1:7 twist rate stabilizes a wide range of 5.56 NATO bullet weights giving the rifle flexibility across common factory loads. The barrel is threaded at the muzzle and capped with an A2 flash hider controlling muzzle flash while keeping the rifle s overall profile familiar to anyone who has handled a traditional AR-15. A gas impingement operating system cycles the action reliably across a broad range of ammunition a proven approach that keeps maintenance straightforward. An aluminum receiver fitted with a Picatinny top rail gives the Penny a reliable standard mounting surface for optics while an M-LOK handguard provides attachment points for lights grips and other accessories along the forend. Magpul furniture rounds out the rifle s ergonomics including a Magpul MOE SL collapsible stock with an adjustable length of pull and a Magpul MOE grip for a secure comfortable hold. A mil-spec trigger and a thumb safety give the rifle straightforward familiar controls for shooters already comfortable with the AR-15 platform. Built for right hand use with a 30 round magazine the Shark Coast Tactical Penny is a dependable rifle for range training or home defense use available for sale at GrabAGun.
