Well, after two range days with more problems than any 10/22 I've ever used, I've decide to send the kit back. Yesterday I posted some problems I had over in the rifle forum. About every 5 rounds I would get a FTE. On top of that every other one of those would get jammed up on top of the bolt assembly to where I couldn't pull it out. I would have to take the rifle apart to pull the kit out. I also had a round fire without being chambered, causing it to explode and blow out the back of the round.
Well, today wasn't much better. I trimmed the spring a couple of coils like Spike's suggests. I had the same problems all day, every 5 to ten rounds (maybe a little less often), but the glaring problem to me is that the hammer will drop no matter how far out of battery the bolt is! Maybe that's normal for a conversion kit, but it's good for me. I didn't have an un-chambered round explode on me today, but I could hear the hammer drop with the bolt wide open (due to the previous round being jammed up on top of the bolt).
Either way, I've emailed the company I ordered from requesting a refund. I think I'll take the refund money and get a MK III, Buckmark, or one of those weird looking Berettas.
If anyone uses this conversion kit, please feel free to give some advice on what the problem might be.
Yesterday's "out of battery" round
Today with a case stuck.
