Anyone have firsthand experience with piston uppers?
In my new gunshop job, I had a coworker that was answering a customer's questions about AR's, and steering him away from the piston uppers with the advice that there have been problems...something about "peening"...but I didn't have time to query him on it. I have heard nothing like that until I overheard his conversation.
Has anyone been familiar with anything like this?
Bullshit?
:cool:
