Geissele 13.5″ Super Modular Rail MK16 M-LOK

The Geissele Super Modular Rail (SMR) MK16 is a free-float M-LOK hand guard for mil-spec AR-15 upper receivers. It mounts with Geissele’s barrel nut, and anti-rotation tabs plus set screws keep it from turning on the receiver. It is machined from 7000-series aluminium and finished in Type 3 hardcoat anodising. The 13.5 in MK16 was adopted by USASOC for its URG-I (Upper Receiver Group – Improved) programme.
