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&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&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&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&slip back out through the slot, and they lock down solid as you tighten the screws more. It&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&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.
