Magpul M-LOK Thumb Shelf FDE

The Magpul M-LOK Thumb Shelf (MAG1566-FDE) is designed for use with octagonal M-LOK handguards or forends. It provides a repeatable reference point for a consistent shooting grip, gives the support hand thumb leverage against muzzle rise, and assists when bracing against a barrier. The shelf is ambidextrous and features a ribbed, curved top surface for improved thumb contact during recoil. Finished in Flat Dark Earth (FDE).
