TacFire MAR102 KeyMod 7-Slot Black Hardcoat Anodized Rail Section - 2.95"

The TacFire MAR102 KeyMod 7-slot rail section is a modular accessory mounting solution built for shooters who want to customize their handguard or chassis layout without overbuilding. This 2.95-inch hardcoat anodized rail uses the KeyMod standard—a lighter, less bulky alternative to full Picatinny systems—making it ideal for AR platforms, chassis rifles, and other modern sporting rifles where real estate is tight and weight matters. Whether you're building a precision setup or a lightweight carbine, a single rail section lets you add exactly what you need: optic mounts, lights, grips, or vertical solutions.

KeyMod's slotted design is thinner and easier to machine than traditional Picatinny, which means less material and faster mounting. The hardcoat anodized finish on this TacFire rail is built to resist wear, corrosion, and the daily scuffs of field use. At nearly 3 inches, this section gives you enough mounting surface for a single accessory or to fill a gap in your layout without requiring a full-length rail.

This is a straightforward, no-frills rail section—solid engineering at a practical price point. If you're filling a specific spot on your gun or experimenting with a new layout, the TacFire MAR102 does exactly what it should. Pair it with compatible KeyMod accessories and keep your rifle lean and configured for the job at hand.

Frequently Asked Questions

What is KeyMod and how does it differ from Picatinny?

KeyMod is a slotted mounting standard that's lighter and thinner than traditional Picatinny rail. Accessories designed for KeyMod slot directly into the rails, making them easier to mount and remove without requiring a full rail system. KeyMod is popular on AR handguards, chassis rifles, and lightweight setups.

What accessories are compatible with this rail section?

Any KeyMod-compatible accessory will mount to this rail—lights, vertical grips, optic mounts, bipods, and more. Make sure the accessory you're pairing with it is KeyMod-standard, not Picatinny.

Will this rail section work on my rifle?

This is a stand-alone rail section designed to mount on KeyMod-slotted surfaces. If your rifle or handguard has KeyMod slots, you can install this rail. It's commonly used on AR platforms and modern chassis systems that support KeyMod standards.

What's included in the package?

The package includes the TacFire MAR102 rail section. Mounting hardware or accessories are not included; you'll need to source compatible KeyMod accessories separately.
