Description
The Geissele MK14 Super Modular Rail (SMR) is a 13.5-inch free-floating handguard designed to provide a slimmer profile and a robust mounting platform for AR-pattern rifles. Precision machined from 6061-T6 aluminum, the SMR pairs light weight with structural rigidity. An updated Geissele barrel nut with a 2.25-inch long surface contact ensures straight, repeatable alignment along the receiver and rail. Magpul M-LOK slots at the 3, 6, and 9 o’clock positions allow secure attachment of accessories while preserving a reduced overall diameter.
