Product Description The Magpul M-LOK Thumb Shelf (MAG1566-ODG) is a purpose-built accessory designed specifically for octagonal M-LOK handguards and forends. Crafted from Magpul&';s proprietary high-strength polymer and finished in OD Green, this thumb shelf delivers a reliable, repeatable reference point for a consistent support-hand shooting grip. It provides the shooter&';s thumb with meaningful leverage against muzzle rise and proves especially valuable when bracing against a barrier. The ambidextrous design ensures compatibility for both left- and right-handed shooters, while the ribbed, curved top surface maximizes thumb contact during recoil for superior muzzle control and enhanced follow-up shot accuracy. Installation requires only a single M-LOK slot, keeping the handguard clean and free for other accessories.
