The Magpul Thumb Shelf is an M-LOK handguard accessory that provides a repeatable reference point for a consistent shooting grip and improved muzzle control during recoil. Its ribbed, curved top surface improves thumb contact, giving shooters leverage against muzzle rise and assistance when braced against barriers.
The ambidextrous design fits both left- and right-handed shooters and installs using only one M-LOK slot. It is compatible with octagonal aluminum handguards only and is molded from Magpul's proprietary polymer with a matte Coyote Brown finish.
