The quad rails we’re known for. Our quad rails have a timeless style and have stood the test of time. They’ve been through many torture tests and have always carried a bombproof reputation. Features include our patent pending vent pattern, anti-rotation QD sockets and standard full length 1913 picatinny rails. Extruded and milled right here in Texas. Each of our rails comes with (1) barrel nut, (1) set of mounting screws and a shim pack.
