This is an almost new Heckler & Koch MR762A1, featuring the H&K Free Floating Rail System quadrail. Comes in like-new condition with four 20 round magazines and Troy flip-up iron sights. Uses the proprietary H&K short-stroke piston gas system as opposed to more traditional AR direct-impingement systems. This gives the MR762A1 its unparalled reputation for reliability in even the harshest conditions. The rifle features a 16.5 inch cold-hammer forged barrel with a 1 in 11 inches twist rate. Designed to function with a variety of 7.62x51mm ammunition. Call Michael's Men's Store in Homer Louisiana for more information.
