HKP Tactical Rail - 6 Inch - HK91/93

I bought 2 of these to install on the sides of the handguard on my PTR91SC. Fit perfectly holes lined up correctly. Just added thread locker to the screws and boom in 5 min I went to having basically a full blown quad rail. (I had already had a rail installed on the bottom section) good quality product haven't had any previous issues in the past and not expecting any in the future.

Excellent. I had them on my PTR-91SC before I sold it, so I had to have them on my new PTR-91. I intend to put a light and laser on them and already added a quick connect mount on the left side rail. I use the HK G-3 sling, so the QD isn't needed but it is there and also has a sling loop if my current G-3 sling ever gets lost or damaged beyond use. The rails just assist in making the rifle more effective once the light and laser are added. I believe all battle rifles should have these items on them to enhance their effectiveness. I also replaced the M-4 stock with a VLTOR stock. Next comes a Primary Arms Variable Power ACSS Raptor Optic. The Rifle is a proven platform but the rails enhance its capabilities.
