Atlas Custom Works Full Metal M-LOK Screw Set, Black

When you're mounting accessories to an M-LOK handguard, the hardware matters more than you think. Cheap steel screws strip after a few adjustments, and polymer fasteners flex under recoil. The Atlas Custom Works M-LOK screw set gives you full metal fittings that hold torque without deforming, so your optic or light stays put between games.

What you get. The set includes the necessary mounting screws and an Allen key for installation. These are standard M-LOK pattern fittings, so they work with any M-LOK slot system — not just Atlas Custom Works handguards. If you've lost screws from a previous setup or picked up a used handguard with incomplete hardware, this fills the gap.

Why metal over polymer. M-LOK relies on T-nuts that slide into the slot and lock against the screw head. Metal screws maintain their thread integrity through repeated removal and reinstallation. They also handle the torque needed to secure heavier accessories like vertical grips or bipods without the head stripping. For lightweight optics or laser modules, polymer might suffice, but metal is the safer call.

Before you buy. This is mounting hardware, not a complete accessory. You'll still need the optic, light, grip, or other device you're attaching. The screws are sized for standard M-LOK T-nuts and slots — if your handguard uses a different mounting system, these won't fit.
