AIM HK 91/G3 (7.62x51/.308) Full Length Handguard - M-LOK

The include hardware had the bolt but not the nut, fortunately the original pin fit so not that big of a deal. Other than that, fits well and enables using MLOK attachments.

This hand guard is definitely an upgrade against the HK plastic hand guard. Fit very well onto the rifle however the front pin recess did need to be enlarged to accept the head for the retainer pin.

Excellent fit and finish on my PTR. Installed a bipod and vertical grip easily onto MLOK handguard.

My PTR 91 came with a super cheap, super loose plastic handguard. Got this and I'm happy I did. Install was quick and easy. Feels and looks great.

The handguard was exactly what I wanted. However, I have a PTR 200 and the handguard didn?t fit in the base cup deep enough so I had to do a little filing and modification to fully seat it and to get the pin will go in. Otherwise I would highly recommend this handguard.

Purchased for my C308. Was a little long so required some modification and had to tighten the bolt down super tight but overall it fits really good. Even though I had to mod it the price is great. The quality is good too.

Pros: light weight, good ventilation and superior modularity to stock handgaurds. Easy install on ptr and well fit Cons: uses an Alan key screw as a replacement for the front pin. Don't know if pin is usable for it, haven't tried. Doesn't make a perfect fit but that's not the most important thing, fits well enough. Stays cooler in my opinion due to ventilation but mag dumps do get pretty hot due to lack of heat shielding. Gloves recommended for that reason.

Looks fantastic.

The previous review here was correct! Cut the end off of the original slim plastic handguard and the ?U? shaped spacer will fit inside the AIM handguard for a perfect fit!

Purchased this product for my C308 because the original heated up way to much at the range. I needed something to keep the barrel cool the hard plastic heated up way to much. I took the original Handguard and cut the end off of it to make contact with the barrel as a spacer once I did that the New Handguard mounted right up and is a very secure fit. Keeps the barrel cool and now my hands aren?t burning. Great product
