The TacFire MAR105S M-Lok Picatinny rail is a compact accessory rail built to expand your firearm's mounting options without taking up valuable real estate on your handguard. At 2.38 inches, this rail bridges the gap between full-length sections and micro setups, giving you flexibility to position lights, lasers, vertical grips, or other tactical attachments exactly where you need them on an M-Lok compatible platform. It's the kind of no-fuss upgrade that makes sense whether you're setting up a defensive rifle, a competition gun, or a hunting platform that benefits from auxiliary accessories.
The black anodized aluminum construction feels solid and rings true to TacFire's straightforward approach to firearm parts—good finish, reliable tolerances, no fluff. M-Lok slots are industry-standard, so your existing accessories will clamp on without drama. The integrated Picatinny top surface gives you traditional dovetail mounting if you prefer standard scope rings or red-dot bases, adding another layer of versatility to a single piece.
Installation is straightforward: align the M-Lok slots with your handguard, snug the fasteners, and you're done. No proprietary tools or gunsmith hours required. It's the kind of bolt-on addition that fits naturally into a build-as-you-go approach, whether you're starting lean and adding capability later or fine-tuning an existing setup.

Yes, if your handguard or rail system has M-Lok slots, the MAR105S will clamp on securely. It's compatible with any firearm platform using M-Lok—AR-15, AR-10, AK platforms with M-Lok rails, and others. Check that your handguard has M-Lok slots before ordering.
The integrated Picatinny top surface accepts any standard Picatinny-mount accessory: scope rings, red-dot sights, lights, lasers, and bipods. The M-Lok sides also accept M-Lok-specific accessories like angle grips or sling mounts if you have fasteners available.
No fasteners are included. You'll need M-Lok hardware (bolts and T-nuts) to secure the rail to your handguard. Many handguards ship with spares, or fasteners are widely available as affordable standalone parts.
