The Free-Floating Quad Rail features a host of upgrades over the standard M4 drop-in quad rail system. The rail utilizes four MIL-STD 1913 rail systems as a mounting interface and incorporates radial cutouts along the length of the rail of the lower overall weight. The barrel nut also serves as screw on base for the outer rail sleeve and is secured by a steel locking ring.
This 7.4" rail is constructed of 6061-T6 aluminum with a black hard coat anodized finish.
