The ArmorMason Cantilever rail mount is a mount for M-LOK and KeyMod handguards. It positions a short MIL-STD-1913 Picatinny rail ahead of the handguard attachment point, providing forward rail space for weapon lights, optics, and other Picatinny-spec accessories without occupying the top rail.

Material: CNC-machined aluminum alloy with a hard-anodized matte black finish for wear resistance and corrosion protection.

Cantilever extension: The Picatinny rail extends between 0.75 and 1.5 inches forward of the M-LOK or KeyMod attachment point. The forward placement allows the mounted accessory to sit ahead of the handguard slot for ergonomic tail-switch reach, clearance from other rail-mounted accessories, and improved support-hand grip placement.

Accessory rail: 3 MIL-STD-1913 Picatinny slots in a low-profile configuration. The footprint is compatible with Surefire-pattern M300 and M600 scout-style flashlights and standard polymer V-Block and ring mounting hardware. Also accepts red and green dot sights, magnifiers, IR lasers, PEQ-15 units, iron sights, sling mounts, and other 1913-spec accessories.

Design: Low-profile body with rounded edges and beveled corners to reduce snag points on slings and gear while keeping accessories close to the handguard.

Mount only. Flashlight, optic, and rifle not included. Check product dimensions and the slot pattern of your handguard before purchase to confirm correct fit.
