The Magpul Thumb Shelf Grip for Octagonal Aluminum M-LOK Handguards, 1 Slot is a rail cover that fits Octagonal Aluminum M-LOK Handguards, offered in Black, Flat Dark Earth, Olive Drab Green.
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.
Rail covers protect your hand and your rail, add grip on the handguard and help manage heat from a hot barrel. Check the attachment type (M-LOK or Picatinny) matches your handguard.
