heads up on the ptr-91's

[cz7]

the locking piece in the ptr is cast !which loses bolt gap fast !to see what you have is pitting on the piece and has no flats like the hk ones near the lug which locks L.P. in the bolt carrier so look at yours and get a hk one for safety and save money on other broken parts !

Can you elaborate on "the locking piece". Do you mean the rollers? I am confused and since I own one, I am concerned if I need to get some replacement parts. Thanks in advance.

Yes, please clarify a bit. I have one, too.

the part that drives out the rollers out is called by hk is the locking piece also guides the firing pin ,locks in to the bolt carrier too ....please get with pof for +4 rollers too ...now my ptr is working well after $300 worth of real hk parts !added in please look for pitting /small holes on the locking piece and look at roller ramps too
