TacFire MAR101 2-Inch Picatinny Rail KeyMod with 5 Slots

The TacFire MAR101 2-inch Picatinny rail with KeyMod slots gives you a modular way to mount accessories on KeyMod-equipped handguards, receivers, and rail systems. This short-profile rail fits tight spaces where you need compact accessory real estate—think mounting a light, laser, or backup sighting solution on a modern AR-platform rifle or tactical shotgun without eating up rail estate. With five Picatinny slots across its 2-inch length, the MAR101 lets you mix and match standard Picatinny-based optics, mounts, and lights in a minimal footprint.

TacFire keeps this piece simple and robust: hard-anodized aluminum construction, KeyMod attachment for compatibility with popular modern handguards, and a straightforward profile that plays well with standard rifle setup conventions. It's the kind of part that fills gaps in your modular build or upgrade—whether you're optimizing a duty rifle, tightening up a hunting platform, or expanding your defensive carbine's versatility without unnecessary bulk.

If you're already running KeyMod on your rifle and need Picatinny mounting points in a compact size, this rail solves that problem cleanly. No over-engineering, no gimmicks—just a solid adapter that does its job and gets out of the way.

Frequently Asked Questions

Is this rail compatible with KeyMod handguards?

Yes. The MAR101 uses KeyMod attachment, so it works with any KeyMod-equipped handguard or rail system that accepts standard KeyMod accessories.

What Picatinny accessories can I mount to it?

Any standard Picatinny-mounted accessory—tactical lights, laser modules, backup iron sight bases, magnifiers, or other optic mounting solutions—will work on the five Picatinny slots.

How many accessories can I attach?

The rail features 5 Picatinny slots across its 2-inch length, so capacity depends on the width of each accessory you're mounting. Most single-width Picatinny items will fit comfortably; some wider accessories may limit the number of simultaneous mounts.

Yes. The MAR101 works on any KeyMod-compatible rifle platform—hunting carbines, duty rifles, or sport shooters. Its compact 2-inch profile makes it ideal when you need Picatinny attachment points without excess bulk.
