The UHPR-HP series of AR-10 Rails are designed for hard use in tactical, competition, or hunting settings. Featuring a full-length Picatinny top rail providing space for forward mounted lights, NV/IR optics, or laser designators. M-LOK slots at the 3, 6, and 9 o'clock positions offer plenty of room for further expansion.

For use on heavier, large frame weapons, the barrel nut and sling QD sockets are crafted from 4140 pre-hardened steel while the attachment/anti-rotation system is 17-4 PH stainless steel. Easy to install, this rail requires no barrel nut shims for installation.
