The Free Float Quad Rail features a host of upgrades over the standard M4 drop-in quad rail system found on many US military rifles.
The barrel nut also serves as screw on base for the outer rail sleeve and is secured by a steel locking ring.
The rail utilizes four MIL-STD 1913 rail systems as a mounting interface and incorporates radial cutouts along the length of the rail to lower overall weight.
