Geissele MK14 13.5in SMR Super Modular Rail Handguard

Description

The Geissele MK14 Super Modular Rail (SMR) is a 13.5-inch free-float handguard designed for AR-15 style platforms. It is precision machined from 6061-T6 aluminum to deliver a rigid, lightweight mounting surface while reducing overall diameter and profile. Magpul’s M-LOK interface at the 3, 6 and 9 o’clock positions allows secure attachment of lights, bipods and other accessories. The MK14 ships with an updated Geissele barrel nut designed for long surface contact and improved rigidity; a Geissele barrel nut wrench is required for installation (sold separately).
