Replacement M-LOK T-Nuts to Repair Your Favorite Accessories
Whether you’re running an M-LOK picatinny rail, light adapter, or foregrip, that accessory is held in place with special T-nuts and matching screws. And, like many other small AR-15 parts, those little nuts and screws can go missing. If you’ve lost track of one, you can use this 10-pack of replacement M-LOK T-nuts to fix up your favorite accessories.
The screws included are a slightly smaller diameter to ensure that they’ll work with a wide variety of M-LOK accessories. The replacement M-LOK T-NUTS work perfectly with any in-spec M-LOK rail, and cam into place for a secure hold. We recommend dabbing a little blue Loctite or equivalent threadlocker on the screw, and letting that cure for 24 hours for a semi-permanent installation.
Be sure to check out our full range of M-LOK handguard accessories if you’re looking for a new part to customize your AR-15!
