Magpul Industries M-LOK Thumb Shelf - OD Green

The Magpul M-LOK Thumb Shelf drops into any standard M-LOK slot and gives the support-hand thumb a positive, repeatable index point on the rifle's handguard. A ribbed, curved top surface improves thumb contact during recoil, helping the shooter maintain muzzle control and a more consistent grip without fighting the gun. The shelf is molded from durable polymer in a matte OD Green finish and ships with the mounting hardware needed for installation.

Purpose-built for octagonal aluminum M-LOK handguards, this single-slot thumb shelf measures just 1.55 in at its maximum length and weighs only 0.4 oz with hardware - a low-profile addition that will not snag on gear or print under a sling. Per Magpul's installation instructions, torque the polymer T-nut to 15 in-lbs for a secure fit on metal or polymer rails.

Whether you are running an AR-15, an AR-10, or any other rifle built on an M-LOK handguard platform, the Magpul M-LOK Thumb Shelf is an easy, no-gunsmithing upgrade for shooters looking to lock in a consistent hand position and tighten up recoil management.
