I bought a Gen1 PA-10 when they first hit the market. It had the usual PA-10 issues (over-gassed), but for under 1k I went for it. I replaced the gas block with an adjustable and put a SF 3 prong flash hider on it. It shoots great and very reliable now. I have only been load testing and can hold 3/4 moa at 100yds. I will soon be ale to go to an 800m range and can't wait to see what it can do there.
