The HK 91 is a workhorse, but the factory furniture leaves you with almost nowhere to hang modern gear. Midwest Industries fixes that with a one-piece M-LOK forearm that replaces the original handguard on HK 91 rifles and popular clones like the PTR 91 and SAR-8. It keeps the slim profile that makes these rifles feel good in the hand while giving you real estate for whatever setup you're chasing.
Machined from 6061 aluminum and hard coat anodized in a matte black finish, this handguard weighs in at just 8.6 ounces with all the hardware installed. The 1.6 inch diameter stays trim so you get a natural grip, whether you're running it toed up near the receiver or pushed out front. Between the 37 full and 7 half M-LOK slots plus the included five-slot rail section, there's room for a weapon light, tape switch, bipod, or a hand stop without crowding anything.
Four anti-rotation QD sling swivel sockets are built right in, so you can set up a two-point or single-point sling exactly where you want it and trust that the swivel won't spin loose. The mil-spec top rail runs the length of the forearm for backup irons or a scanning optic, and the whole thing is backed by the Midwest Industries lifetime warranty.
This is one of the easier upgrades you'll make to an old-school 308 platform. It's a direct replacement for the factory handguard and includes all the tools you need in the box, with torque specs printed in the instructions so you can snug it down right. Folks who have swapped these onto aging SAR-8 and PTR 91 builds consistently call out the tight fit and clean finish, and the modular layout means you can dial in your rifle for the range or the field however you like. Note that this one is not designed for CTME 308 rifles.

This is one of the simpler upgrades on the platform. It comes with all the tools you need and the instructions include torque specs, so most folks can have it on in a few minutes with a torque driver. Owners regularly mention how clean and tight the fit is once it's on.
