Midwest Industries MISP89M MP5K M-LOK Handguard - Black Aluminum for HK MP5K

The Midwest Industries MISP89M MP5K M-LOK handguard is a drop-in upgrade for semi-automatic MP5K platforms, letting you modernize your carbine's rail system without gunsmithing. Built from 6061 aluminum with a hard-coat black anodize, this one-piece design is lightweight and durable—designed to handle the demands of the range, competition, or duty use. Whether you're running optics, lights, or other tactical accessories, the M-LOK slots and top Picatinny rail give you the mounting flexibility to build exactly the setup you need.

Midwest Industries engineered this handguard for a direct drop-in fit on MP5K variants, and it ships with all the hardware required for installation. The 1.6-inch diameter profile keeps the ergonomics intact while the nine M-LOK slots distributed along the forend let you attach gear exactly where you want it. At just 2.6 ounces, it won't add unnecessary weight to an already handy platform. The included 5-slot M-LOK rail segment gives you a quick-attach point for common accessories, and the top Picatinny rail is milled to military specification for reliable optic mounting.

This is a 922R-compliant component, and every handguard is manufactured in the USA. If you own an MP5K semi-auto and want a modern, practical way to add mounted accessories without drilling and tapping, this is the straightforward upgrade path.

Frequently Asked Questions

Will this handguard fit my MP5K?

The Midwest Industries MISP89M is designed as a drop-in handguard for HK MP5K semi-automatic variants. Verify your platform is an MP5K before purchase, as this is not compatible with full-size MP5 models.

What accessories can I mount with the M-LOK slots?

M-LOK is an industry-standard mounting system. Any M-LOK-compatible light, vertical grip, sling mount, or other tactical accessory will attach to the nine M-LOK slots on this handguard. The top Picatinny rail accepts standard Picatinny-mount optics and accessories.

Is installation difficult?

This is a drop-in design, meaning it replaces your existing handguard without permanent modification to your receiver. All necessary installation hardware is included, though specific installation steps should be confirmed with Midwest Industries or your gunsmith if you're unfamiliar with MP5K takedown.

Does this handguard add weight?

At 2.6 ounces, the MISP89M is quite lightweight. The aluminum construction keeps it minimal while the hard-coat anodize provides durability without significant heft.
