CMC Triggers 81722 5-Slot Picatinny Rail, 2.50" Length, 0.40" Height, M-LOK, Matte Black Aluminum

The CMC Triggers 81722 5-Slot Picatinny Rail is a compact aluminum accessory rail built to add tactical mounting capability to any M-LOK compatible handguard or forend. At 2.50 inches long and 0.40 inches tall, this rail bridges the gap between your existing M-LOK slots and standard Picatinny-spec accessories—giving you flexible, modular options for lights, vertical grips, and other rail-mounted gear without replacing your entire handguard. Made in the USA from mil-spec anodized aluminum, it's built tough enough for serious shooting and practical enough for everyday field use.

CMC's design philosophy keeps things straightforward: a precision-machined aluminum profile with five Picatinny slots, beveled edges that won't snag on your pack or gear, and all mounting hardware included. At just 0.7 ounces, it adds virtually no weight to your rifle. Whether you're running a precision rifle, an AR platform, or any other modern tactical rifle, this rail lets you customize your setup as your mission or hunting scenario demands—without the guesswork or hunting for obscure fasteners.

Installation is straightforward: the rail slides directly onto M-LOK slots on aluminum or polymer handguards, secures with the provided hardware, and you're ready to mount whatever accessory makes sense for your shooting. The matte black anodized finish matches most modern rifle furniture and resists glare. This is practical modularity for hunters, competition shooters, and tactical riflemen who want to build a setup that works for them, not the other way around.
