Aim Sports MMH94 Extended M-LOK Handguard - 6061-T6 Aluminum, Black Anodized Finish for HK 91/G3

The Aim Sports MMH94 Extended M-LOK Handguard brings modern rail modularity to the HK 91 and G3 platform, giving you a lightweight, durable upgrade over factory furniture. Built from 6061-T6 aluminum and finished in hard-anodized black, this extended handguard provides a longer sight radius and more real estate for mounting tactical accessories—lights, lasers, foregrips, or rail-mounted slings—without adding unnecessary weight. If you're running an HK 91 or G3 and want to adapt your rifle for modern optics and accessories, this is the kind of practical upgrade that makes a real difference at the range or in the field.

M-LOK mounting slots give you industry-standard compatibility and the flexibility to arrange your gear exactly how you want it. The extended length also improves ergonomics and control, especially if you're moving between closer and longer-range work. The 6061-T6 aluminum core resists corrosion and handles recoil without flex, while the black anodized finish resists wear and matches most tactical setups.

Installation and functionality depend on your specific rifle's barrel assembly and existing furniture configuration, so verify fitment with your HK 91 or G3 variant before purchase. This is a no-frills, purpose-built accessory for shooters who know their platform and want to modernize it without major gunsmithing.
