M-LOK

What M-Lok is

M-Lok is a standardised accessory mounting system built into the slots of your handguard. Instead of running a full-length Picatinny rail — adding weight and bulk whether you use it or not — M-Lok lets you attach accessories only where you actually want them. Each one locks in from behind via a pair of T-nuts, creating a secure and repeatable attachment with basic tools.

If your handguard has M-Lok slots, your gun is already ready for everything in this category.

What you can do with M-Lok

• Add grip surfaces – grips fill slots on the sides of the handguard and give your support hand more to hold. Useful when the bare handguard profile is too narrow or smooth for a confident grip under recoil.
• Add a hand stop – a hand stop gives your forward hand a consistent reference point and prevents it from drifting forward. Repeatable forward hand position means a more consistent support grip on every shot and every draw.
• Add Picatinny sections – for accessories that use Picatinny mounting — lights, lasers, bipods — a short M-Lok rail section gives you the interface you need without committing a full rail to the entire handguard.
• Add a finger rest – a ledge that gives your index finger a fixed resting point forward of the trigger guard, helping maintain consistent support hand pressure and placement.

Before you order

M-Lok is standardised but accessories vary in how many slots they occupy, their profile height, and the clearance they need. Check that your handguard has available slots in the positions you want and enough room without obstruction from the barrel, gas block, or other components. All dimensions are listed on the individual product page.
