Trinity Force MX-15 M-LOK Free Float Rail

The MX-15 M-LOK 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 MX-15 Rail is the ideal solution for any AR-15 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.

The Mx series 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.
