Would be 5 stars if it was machined for hk accessory carrying handle. - Midwest Industries 91 Clones Mil-Spec Top Rail Handguard, M-Lok Compatible

Bought this mainly to allow better barrel cooling on my old Hk91. Saved a lot of weight ditching the wide body plastic handguard and factory steel bipod for this piece and the Midwest Industries M-Loc Harris bipod mount.
Fit, finish, and hand feel of the aluminum rail is excellent. The hard anodized finish is just the ticket for durability.

Only gripe is that I have the factory carrying handle installed and I wasn’t going to take it off. This requires some cutting of the rail with a steady hand, Dremel grinder, cut-off wheel, and pair of calipers. I guess it makes sense to design it for the 95% of guns that don’t have a handle. Turned out well, but it was a risky chance for serious cosmetic damage.

I would recommend this rail to modernize your vintage Hk platform, and it is removable to not alter the rifle’s value. Tip, use a low strength loctite thread locking compound if you want to switch handguards back and forth.
