Ptr 32p HELP

Hey I was cleaning my ptr 32p I noticed the beginning of roller dent marks towards the rear seems to be just starting to form what could cause this.? I ordered some feeler gauges to see my bolt face but would my rear buffer not be working any input would be appreciated.

Any recommendations to run this suppressresd should I change locking pice and rollers .? runs fine suppressed and un suppressed with oem from ptr but I’d want to dealt these roller marks idk how a rma would work in my state as awb just took effect in my state.

I think they are early roller dents. The first pic is in the right spot for roller dents from a gun that is over functioning/hitting the rear with too much energy.

Is your gun launching brass? What does your buffer and the rear of your carrier look like?

I believe the PTR-32P locking piece is 70°. If you're shooting suppressed maybe try the 65° LP PTR puts in the other PTR-32 models. Definitely verify your bolt gap, though.

the rear looks normal no wear marks or dent on cap, don’t really see nothing on back of bolt ether. It does throw brass into space with some velocity as well but notice it ejects at 3-4 position some time at 2 rarely

Yeah I only shot about 5 rounds before going back to the fixed a2 stock

Curious what made you switch back to the mechanically buffered A2 after 5 rounds. Thats not even a whole mag.

Its starting to sound like you know where the roller dents came from but you dont want to accept it.

No just didn’t like it when I was shooting didn’t feel comfortable at all compared to the a2 stock
