GrovTec US 3" M-LOK Rail, 7 Slot Tactical Accessory Mount

The GrovTec US 3" M-LOK rail is a solid choice for shooters who want to add optics, lights, lasers, or other tactical accessories to their rifle without committing to a full handguard replacement. This compact 7-slot rail mounts directly to M-LOK slots on your existing handguard or foregrip, giving you real estate where you need it most. Built from aluminum and finished in Type III Black Anodize, it's tough enough for field use and light enough that it won't bog down your setup.

The rail follows the MIL-STD 1913 Picatinny pattern, so it plays nice with the vast majority of modern tactical mounts—whether you're running a pressure switch for a weapon light, a laser aiming module, or an optic riser. The CNC precision machining means consistent, tight tolerances; no rocking or shifting once your gear is locked down. Installation is straightforward: drop it in, align it, tighten the M-LOK fasteners, and you're done. Hardware and an allen key come in the box.

GrovTec US products are trusted by hunters, competition shooters, and tactical enthusiasts who refuse to compromise on quality. If your rifle or carbine has M-LOK mounting capability and you need a clean, reliable way to integrate additional gear, this 3-inch rail gives you the flexibility without the bulk.

Frequently Asked Questions

What accessories can I mount on this M-LOK rail?

Any accessory with a standard MIL-STD 1913 Picatinny mount will work—weapon lights, laser modules, offset optics, angled grips, sling attachments, and more. Compatibility depends on the specific accessory, not the rail.

Is this rail compatible with my rifle?

If your rifle or handguard has M-LOK mounting slots, this rail will fit. M-LOK is a common standard on modern AR-pattern rifles, AK platforms, and many aftermarket handguards. Check your handguard documentation to confirm M-LOK capability.

What's included in the box?

The rail ships with installation hardware and an allen key for mounting to M-LOK slots.

How durable is the anodized finish?

Type III Black Anodize is a hard-coat finish designed for tactical and field use. It resists corrosion and wear better than standard anodize, though like any finish it can show marks with heavy use—that's normal and doesn't affect function.
