Great little gun, $400 seems to be a fair deal on them. I put ~3,000 rounds through mine in the first year and only had an issue with two clips of remington ammo (it feeds EVERYTHING ELSE perfectly) I will advise
you to keep it extremely clean, and always wear hearing and eye protection...just ask me why....(I'll give you a hint...mine is currently in the shop with a blown out extractor and firing pin...)
