CMT Tactical AR-10 UHPR MOD 2-HP .308/7.62 RAILS - 13.7"


The CMT UHPR™-HP series of AR10 Rails are designed from the ground up for hard use either in tactical, competition or hunting scenarios. To withstand the rigors placed on heavier large frame weapons we have opted to utilize 4140 Pre-hardened material for the barrel nut & sling QD sockets. We use 17-4 PH stainless steel on the Patent Pending attachment/anti-rotation system, never opting for lessor/cheaper materials at these critical load bearing points.
