Magpul M-LOK Thumb Shelf ODG

This OD Green Magpul M-LOK Thumb Shelf gives your support hand thumb a consistent place to land on an octagonal M-LOK handguard or forend. With the thumb indexed in the same spot each time, your grip stays repeatable, and the thumb can lever against the shelf to hold the muzzle down. It helps too when the gun is braced against a barrier.

A ribbed, curved top keeps the thumb in contact during recoil for better muzzle control. Either hand can use it, since the shelf is ambidextrous, and it is molded from Magpul polymer.
