RAINIER ARMS 308 RAIL
From RAINiER ARMS---Description: The RA10 Rail System features some of the latest advancements in available today. We added a second QD swivel up front (where most shooters use with the 2 pt sling), added weight reducing triangle vent holes, and modified the clamping system (moved further forward) to add stability to the entire system. The RA10 rail system comes in 2 sizes 11 and 13. The RA10 is designed to work with low profile gas blocks and provides a stable rail system for any accessory. Barrel nuts come standard on our rail system and you have the choice between ARMALITE & DPMS patterns. Barrel Nut Included: $30 Value
