Simply from a reliability/accuracy standpoint, is there any noticeable difference? Found an HK91 for a "reasonable" price.
IMHO - no, the PTR-91 was built to take advantage of the scrapped surplus HK-91s, you’re typically going to buy HK branded parts to repair/replace anything on the PTR.
My only compliant with my PTR GI was heavily used HK ODG stocks, on a “new” rifle.
It went bang with everything I put in the magazine, but just lost interest in it after a while.
