Geissele MK16 15″ Super Modular Rail M-LOK

Geissele 15″ 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.

The 15 in length suits rifle builds where a long hand guard is wanted for a forward grip and full-length accessory space.

• Free-float design, mounts with the Geissele barrel nut
• Anti-rotation tabs and set screws lock the rail to the upper receiver
• Full-length M1913 Picatinny rail on top

Designed for mil-spec M4/AR-15 upper receivers; compatibility with billet receivers is not confirmed by the maker. A Geissele barrel nut wrench is needed to install the rail (sold separately). Installation by a gunsmith is recommended. Available in Black and DDC. DDC = Geissele Desert Dirt Color.
