Description
Sometimes all you need is a little extra real estate. The Timber Creek Outdoors M-LOK 3-Slot Picatinny Rail hands you three slots of 1913 Picatinny mounting space that clamp right onto any M-LOK handguard or forend. It bolts up wherever you need it, whether that's a light out at the muzzle, a laser at three o'clock, or a hand stop down low, and it does so without changing how the rest of your rifle is laid out.
Timber Creek machines these from aircraft-grade billet aluminum and wraps them in a hardcoat anodized OD Green finish. That means it shrugs off the usual abuse from range days, hunts, and truck-gun duty without wearing through or corroding. The OD Green pairs well with earth-tone builds and blends nicely into a hunting or field setup if you'd rather not run flat black on everything.
Why the Timber Creek 3-Slot Rail Earns Its Spot
Three slots is the sweet spot for single-accessory jobs. You get enough length to lock down a weapon light, a pressure switch mount, or a QD sling adapter, but the profile stays short and light so you're not adding dead weight to the handguard. Since it uses the M-LOK interface, you can move it, add slots at multiple clock positions, and dial in your setup exactly how you like it.
Installing the OD Green M-LOK Rail Section
Installation is about as simple as AR accessories get. The rail ships with the T-nuts and screws you need, so you drop the T-nuts into your M-LOK slots, line up the rail, and snug down the hardware with an Allen wrench. Fits both AR-15 and AR-10 pattern handguards that use the M-LOK standard, so it plays nice with just about any modern modular build you've got.

Frequently Asked Questions
Will the Timber Creek M-LOK 3-Slot Rail fit my handguard?
It works with any handguard or forend that uses the M-LOK mounting standard, which covers most modern AR-15 and AR-10 builds. As long as your handguard has M-LOK slots, this rail will bolt right up. It uses standard M-LOK T-nut spacing, so compatibility is rarely an issue.
Does this 3-slot rail come with the hardware to install it?
Yes. Timber Creek includes the T-nuts and screws needed to mount it, so you won't need to source anything separately. All you'll want on hand is an Allen wrench to snug everything down.
What can I mount on a 3-slot Picatinny rail?
Three slots gives you room for a single accessory like a weapon light, laser, pressure switch mount, hand stop, or QD sling adapter. It's built for adding one dedicated mounting point rather than a long run of accessories. If you need more space, Timber Creek makes this same rail in longer 5, 9, and 15 slot versions.
Is the OD Green finish durable?
It's a Type III hardcoat anodized finish over billet aluminum, which is the tough, wear-resistant coating you want on a working rifle part. It holds up to scratches, moisture, and general field use without corroding. The OD Green tone also blends well with earth-tone and hunting builds.
