When mounting an accessory with the M-Lok system, you don’t need access to the backside of your rail. M-Lok works great with non-metal mount surfaces, making them a great option for use with polymer accessories. Unlike the rough, cheese-grater feel of a Picatinny rail, the M-lok has a smoother feel and is much easier on your hands, clothing, and the inside of your rifle case. This eliminates the need for a large and heavy Picatinny rail that runs the length of your weapon. M-Lok allows you to mount a small rail or accessory directly to your rifle’s hand guard. There are many benefits of using an M-Lok rail over other rails systems. Free licensing is great for the consumer, because it ensures consistency and compatibility between all M-Lok products, no matter the manufacturer. This means that, although M-Lok is free for other companies to use, companies must first obtain a free license from Magpul to manufacture M-Lok products. This can negatively affect shooting, especially since that extra weight tends to build up on the fore end of your rifle.Īlthough developed and patented by Magpul, the M-lok system is a free-license design. The main problem with the Picatinny rail is it can add excessive weight and bulk. When compared to the Picatinny rail (the current gold-standard mounting system), The M-Lok rail is simpler, more lightweight, and extremely versatile. And, you can mount it EXACTLY where you need it.Ĭurrently, M-Lok is competing with KeyMod (an open sourced system developed by a partnership between VLTOR and Noveske) to replace the Picatinny rail. In basic terms, M-Lok allows you to mount just about anything to your rail system without having to remove the rail. It would be surprising if these handguards couldn’t accommodate a can since AAC is best-known for their suppressor products.M-Lok (short for Modular Lock) is a mounting system that allows you to attach accessories- like an optic, laser, flashlight, or bipod - to a negative space mounting point. These handguards have an inner diameter of 1.3 inches, which is wide enough to fit around many rifle suppressors. The design is octagonal and offers seven rows of SquareDrop sections with a standard Picatinny rail at 12 o’clock. AAC lists their weights at 6.4, 9 and 10.5 ounces, respectively.
It also appears to remove more material than other negative mounting space standards which makes these handguards especially light.ĪAC is kicking off their SquareDrop handguards in three lengths: 8 inches, 10.2 inches and 13.5 inches. In the war between rail standards, a lot of people prefer Magpul’s M-Lok (or even the old Picatinny rail) based on looks alone. SquareDrop addresses one criticism a lot of people have regarding KeyMod: the looks. The system unlocks easily for handguard removal. Anti-rotation tabs prevent the handguard from twisting off. This turnbuckle screw fixes the handguard to the barrel nut.
