Description

The HK91 and G3 platforms are legends, but the skinny factory forends leave a lot on the table when it comes to running modern gear. The Aim Sports MMH94 fixes that. It's a one-piece, drop-in handguard machined from 6061-T6 aluminum and finished in black hard coat anodize, so it holds up to real use and looks the part next to your rifle's original profile. You get roughly 3.4 inches of rail space forward of the front sight, plus a swappable top section that lets you run either Picatinny or M-LOK up top depending on how you like your optics and irons set up.

Why the MMH94 Beats the Old Skinny Forend

With 37 full and 7 half M-LOK slots spread around the body, there's plenty of real estate to hang a weapon light, laser, bipod, or hand stop wherever your grip lands. The extended length runs out past the front sight, which gives you more room to spread your support hand and mount gear farther forward. It's still light in the hand, so you keep the balance that makes these rifles fun to run without adding a bunch of nose weight.

Installing the Aim Sports HK91/G3 Handguard

Installation is straightforward and comes with the hardware you need, including U.S.-made steel mounting bolts and anti-rotation hardware to keep everything locked in place. On a genuine HK91, G3, or a quality clone like a PTR-91, it's a clean drop-in job at your own bench. Owners consistently report a snug, tight fit on PTR rifles with a look that dresses the gun up nicely.

Getting the Most Out of the MMH94

If you plan on running a light or shooting long strings, M-LOK rail covers are a smart add since aluminum will pick up heat off the barrel. Note that CETME and some C308-pattern rifles can require minor fitting to seat the handguard properly, so those builds may need a little bench work rather than a straight drop-in. For a true HK or PTR, though, you're looking at a simple upgrade that modernizes a classic platform in an afternoon.

Frequently Asked Questions

Will the MMH94 handguard fit my PTR-91?

Yes, it's designed for HK91 and G3 rifles and drops in cleanly on quality clones like the PTR-91. Owners regularly report a snug, tight fit on PTR rifles with no wiggle. It gives the gun a more modern look while keeping the classic HK profile.

Do I need a gunsmith to install this handguard?

On a genuine HK91, G3, or PTR-91, it's a straightforward drop-in job you can handle at your own bench with the included hardware and tools. CETME and some C308-pattern rifles are the exception and may need minor fitting to seat correctly. For most true HK-pattern rifles, no gunsmithing is required.

Can I run both Picatinny and M-LOK on top?

The MMH94 ships with two swappable top sections, one Picatinny and one M-LOK, so you can set the top up whichever way suits your build. The body itself uses the Magpul M-LOK system with plenty of slots around the sides and bottom. That gives you flexibility for optics, irons, and accessory placement.

Does it get hot when running a light or shooting a lot?

It's aluminum, so it will pick up heat off the barrel during longer strings of fire, same as any metal handguard. Adding a few M-LOK rail covers where you grip is a cheap and easy fix. It keeps your support hand comfortable and protects your gear.
