The Atlas 308 Keymod Free Float Rail features a slim profile for improved ergonomics and weight savings. With a static top rail optimized for mounting optics and multiple contact points for a hex key mounted modular rail system on the sides and bottom, the Atlas Rail is the ideal solution for any AR10 or LR 308 owner looking for speed and mission flexibility. It uses a hex key secured barrel nut clamp and proprietary barrel nut for even more weight savings and easy installation. This rail system is designed to be compatible with the HIGH PROFILE Aero Precision 308 upper receiver (Gen 1) and does not mount flush with DPMS pattern low profile upper receivers.
The Atlas 308 Rail features a non-indexing barrel nut and clamping system (FREELOK) that utilizes free floating tabs to secure the rail to the receiver. FREELOK provides both frictional and mechanical locking forces to create a rock-solid bond between the rail and barrel nut.
