Geissele Automatics Super Modular Rail MK16 M-LOK 10.5" AR-15 Handguard - Black

The Geissele Automatics Super Modular Rail MK16 is a precision-machined free-float handguard purpose-built for the MK16 / AR-15 platform. At just 11 oz, it provides a rigid, lightweight upgrade over standard drop-in handguards while preserving the strength Geissele rails are known for.

The handguard is CNC-machined from 7000 Series Aluminum and finished in a Type 3 hardcoat anodized black coating for serious corrosion and wear resistance. At 10.5" long, it offers a 1.26" inner diameter, a 1.59" outer diameter (DAQ), and an overall 2.39" height while keeping weight at 11 oz (12.6 oz with the included barrel nut).

A continuous Picatinny top rail runs the full length of the MK16, giving you a rigid, optics-ready platform for red dots, holographic sights, magnified optics, back-up iron sights, or clip-on night vision. The sides and bottom are machined with M-LOK slots for lights, lasers, foregrips, and other accessories. Anti-rotation tabs and set screws lock the rail to the receiver, and a matched Geissele barrel nut is included for a clean, return-to-zero installation.
