Midwest Industries HK MP5/SP5 M-LOK Aluminum Matte Handguard$136.95
Availability: In Stock
The Midwest Industries HK 91 M-LOK aluminum matte handguard brings modern modular flexibility to your HK 91 rifle platform. Built as a one-piece drop-in replacement from 6061 aluminum with a hard-coat anodized matte finish, this handguard trades the factory furniture for a rock-solid mounting solution that opens up serious accessory options without permanent modifications. If you've been running HK 91s and wishing for the kind of rail real estate AR shooters take for granted, this upgrade delivers it.
The real advantage here is M-LOK compatibility across 37 full slots, giving you the ability to attach lights, lasers, grips, bipods, and other tactical accessories exactly where you need them. One five-slot M-LOK rail ships included, letting you get mounted up right out of the box. The one-piece design keeps things light—8.6 ounces—and rigid, with a 1.6-inch diameter that maintains handling balance. Installation is straightforward with tools provided, and the handguard is 922R compliant, so it integrates cleanly into the rifle's architecture.
This is purpose-built for HK 91 owners who want to modernize their platform without changing what makes the rifle function. It won't fit CETME 308 rifles, so verify your platform before ordering. Whether you're setting up a dedicated range gun, a hunting rifle needing a light, or just want the tactical flexibility HK 91 users have been missing, this handguard is a no-nonsense upgrade that actually sticks.
