The Midwest Industries HK91 M-LOK Handguard (brand part no. MI-HK91M) brings modern M-LOK modularity to a classic platform, fitting the HK91 and its clones. It replaces the factory handguard with a design that gives you 37 full and 7 half M-LOK slots for mounting lights, foregrips, and other tactical accessories anywhere along its length. A five-slot M-LOK compatible accessory rail is included in the box, so you have a Picatinny mounting point ready to go without buying it separately. Four anti-rotation QD sling swivel sockets round out the mounting options for a sling setup. Midwest Industries machines the handguard from 6061 aluminum with a hard-coat anodized black finish, keeping it lightweight and corrosion-resistant on a platform that rarely sees this level of accessory support.
