Not sure of an actual round count on my Osprey45. I'd give a rough estimate of 2000. I took it out today and put a few hundred more down range. Performance is good. I had noticed that the O ring was starting to get frayed, but had always been hesitant to replace it. I bought a bag of replacements, and decided that today was the day. I took an x acto and popped out the old ring. Lubed a new one with a little fire clean and popped it into the groove. I guess for some strange reason I had envisioned it being more of a pain in the arse.
I also found out the an AR carbon scraper does a bang up job on the pistons too.
