I have a Clarke trigger group in my 10/22. It was the first gun I really modified and I didn't feel qualified so I sent it to them. It is nice and smoothe and not as expensive as you would think. I might let them do my next one also even though I think I could do it know. On a side note and I certainly don't want to get anything started but I think they were the first people to put the bull barrel on the 10/22's.
