Quick Tip: How To Mount M-LOK Accessories

We often hear a lot about how great the M-LOK® system is for mounting accessories on AR-15 handguards. But HOW do you do it? How exactly do you use M-LOK's cammed T-nut fasteners to install those accessories? Sit back because Brownells Gun Tech™ Caleb Savant is going to show us exactly how it works by installing a Picatinny rail segment on his AR-15's M-LOK handguard. And installing ANY M-LOK accessory works pretty much the same way. The M-LOK system eliminates the M1913 Picatinny railed handguard's bulk, weight, and tendency to remove skin from your hand. (To get a full comparison of M-LOK to Picatinny and KeyMod, search for our Smyth Busters video, "M-LOK vs. KeyMod - Which is Better?") With M-LOK a pair of screws go through the accessory into little T-nut mounting plates that slip through slots in the handguard. As you tighten the screws, the plates rotate 90 degrees so they can't slip back out through the slot, and they lock down solid as you tighten the screws more. It's easier done than said! Removing the M-LOK accessory is even EASIER. Oh, now you want to put it back on? Reinstalling is almost as easy. Bonus benefit: M-LOK's excellent return-to-zero capability.

The M-LOK® system was originally developed by Magpul, who licenses it to other manufacturers free of charge, as long as those manufacturers ensure their products meet the M-LOK specs and display the M-LOK® logo on their products.
