Magpul M-lok T-nut Replacement Set

The Magpul M-LOK T-Nut Replacement Set is a hardware pack engineered to maintain and repair M-LOK-equipped firearms and tactical accessories. This replacement set addresses a critical need for operators and gunsmiths who service weapons configured with M-LOK mounting systems—whether during field maintenance, modular reconfiguration, or accessory swaps. Manufactured from 4140 chromoly steel with a mil-spec manganese phosphate finish, the hardware delivers corrosion resistance and durability consistent with military-grade standards.

The set contains two T-nuts and two distinct button-head cap screws of different lengths, accommodating varying handguard and forend thicknesses without requiring multiple SKUs or inventory management. The inclusion of self-locking reusable thread patches on the screws ensures secure fastening upon installation and reduces the risk of fastener rotation under recoil or field handling. This engineering choice eliminates the need for thread-locking compounds, streamlining field repairs and allowing faster tactical reconfiguration.

This replacement set is essential for anyone operating M-LOK accessory-dependent systems, including AR-pattern rifles with M-LOK rails, precision rifles with modular handguards, and tactical shotguns equipped with M-LOK mounting surfaces. Maintenance teams, armourers, and operators who rotate accessories or perform field-level repairs will find this kit indispensable for continuity of service. The product is manufactured in the USA, meeting domestic sourcing requirements for military and law enforcement procurement.
