M-LOK Thumb Shelf

The ambidextrous M-LOK Thumb Shelf increases muzzle control and support-hand consistency to get back on target faster, improving follow-up shot speed. The shelf features a ribbed, curved top for improved thumb contact during recoil, resulting in better muzzle control, and provides assistance when braced against a barrier. Designed for octagonal M-LOK handguards or forends, and molded from Magpul's proprietary polymer.
