I traded for a new PTR 91 GI yesterday and noticed that the paddle release is fitted by what I thought was a "non-approved" method by the ATF. Raised a few questions, essentially : - are rules for the 91 different than the MP5 ? -does PTR have some special dispensation for this method? -or do I...

Hello, I recently bought a Z24 for my PTR91, i tried to mount it but it is impossible to do, when I try to pull the lever to lock it, it blocks as i cannot go further through the ptr itself and i still have like 1mm to go to lock it. Has someone else ever got this issue? How can i fix that...

New here and hope y’all can help. Any one know of a good US smith for swapping out a barrel on a PTR91? I’ve seen a few post on some good places but they were all from at least 6 years ago. Bought it years ago with the intent on doing my own interpretation of a PSG1. My girlfriend recently...

Good evening! I have the opportunity to buy a PTR-91, low round count, with serial Aw2***. I've read about the fluting problem with these models. If it turns out to be an issue, are there still those that will correct the flutes? Also, are there any other problems that have come up with...

First post on the HK forum here. I bought a PTR-91 kit earlier this summer and I figured it might be cheaper to build it instead of buying it (probably a bit more fun too). I'll probably start in a few weeks here, brushing up on my MIG and TIG welding skills before I even think about touching my...

I was told my PTR91 (by the company) barrel is a standard HK 15x1MM Right Hand thread twist. Is that the same for the HK91 and G3 model rifles?

I emailed PTR91 and gave them my serial number and asked if they kept records on what parts were US made. The rep said these parts in my PTR GI should be US made parts. 1) Reciever 2) Barrel 3) Flash Hider 4) Trunnion 5) Pistol Grip 6) Bolt Head 7) Bolt Carrier He also said this, "The hammer...
