G&G Armament have shared details of their new M-LOK Rail for the PCC45 / MXC 9:
The 5″ M-LOK Polymer Rail XXVI for the MXC 9 or PCC45 AEG is the perfect replacement or custom project. With a Picatinny rail on top and M-LOK Slots on the sides and bottom, there is plenty of real estate for scopes, optics, and tactical accessories. An integrated handstop on the bottom of the rail aids in improved ergonomics and handling.
