Geissele Automatics Super Modular Rail MK14 10.50" M-LOK AR-15 Handguard - Desert Dirt

The Geissele Automatics Super Modular Rail MK14 is a 10.50" free-float handguard purpose-built for M4 Carbine mil-spec flat top upper receivers. Cut from 7000 Series Aluminum and finished in Geissele's signature Desert Dirt Color (DDC) hardcoat anodize, the MK14 delivers a slimmer overall diameter and reduced height compared to the larger MK4 and MK8 rails, giving your build a more compact handling package without sacrificing the rigidity Geissele rails are known for.

The MK14 uses a continuous Picatinny top rail that aligns with the host upper's rail for optics and back-up iron sights, with M-LOK slots along the sides and bottom for mounting accessories, lights, and grips. The free-float design clamps over a standard barrel nut and promotes consistent barrel harmonics for accuracy. Because the rail sits over the gas block area, the MK14 must be used with a low-profile gas block such as the Geissele Super Gas Block (SGB).

Designed, machined, and finished to Geissele's exacting standards, the Super Modular Rail MK14 drops onto your AR-15/M4 build and pairs cleanly with matching Desert Dirt Color Geissele uppers, receivers, and triggers for a coordinated look.
