This is the KeyMod version of our new DPMS Evolution Rail. It will accept all of our KeyMod accessories. The DPMS Evolution Rail is an adaptation of our popular Evolution Series rail. This rail is built specifically for the DPMS LR308 receiver geometry. Included is a modified DPMS barrel nut which is required for installation. No thermal bushings are required for installation. Will fit any .308 upper receiver with new DPMS low profile receiver height (i.e. S&W M&P10).FEATURES:
