MI M-LOK Extended Beam Black - Tactical Rail Accessory

The Midwest Industries M-LOK Extended Beam is a tactical rail accessory designed to relocate your M-LOK-compatible light forward on your rifle or carbine. If you run a SureFire Scout Light Pro Series or another M-LOK light and find yourself wrestling with shadow cast by your handguard or gas block, this simple aluminum extension solves that problem. By moving your light 3 inches forward, you get better target illumination and reduce the dead zone directly in front of your muzzle—critical for home defense, duty carbines, or competitive shooting where every sight picture matters.

Beyond the shadow reduction, the extended beam frees up additional M-LOK real estate on your handguard. That means you can stack other accessories—a pressure switch, cable management, a secondary light, or a forward grip—without sacrificing light placement. It's a straightforward mechanical solution: hard-coat anodized 6061 aluminum keeps it lightweight (just 1 ounce) and durable, and the design is American-made, so you know the tolerances are tight.

This accessory works with SureFire Scout Light Pro Series fixtures and is compatible with other M-LOK-mounted lights on the market. If you're already locked into the M-LOK ecosystem and need to dial in your light position, this beam extension is one of the cleanest ways to do it without replacing your entire light assembly or handguard.

Frequently Asked Questions

Will this work with my SureFire Scout Light Pro?

Yes. The M-LOK Extended Beam is designed specifically for SureFire Scout Light Pro Series lights, as well as other M-LOK-compatible lights.

How much does moving my light forward reduce shadow?

By extending your light 3 inches forward, you push the light further ahead of handguard obstructions and gas blocks, significantly reducing the shadow cast in your primary target zone. The exact improvement depends on your handguard design and light output, but most shooters notice an immediate difference in sight picture.

Can I use other M-LOK accessories with this beam?

Yes. The extended beam is designed to free up additional M-LOK rail space, so you can mount pressure switches, cable clips, or other M-LOK accessories alongside it on your handguard.

What's included with the M-LOK Extended Beam?

The package includes the aluminum extension beam itself. All M-LOK mounting hardware is standard across the system, so if your light and handguard are already M-LOK-equipped, you'll have everything you need to install it.
