I agree with zippo, go with the complete trigger assembly whichever one you buy. I got a volquartsen assembly, and it went in like butter. Also I am NOT a gunsmith or good with tools. I looked on youtube and found a lot of videos on replacing a trigger assembly...enough that I could see how todo it. While I'm here...has anyone used a laser boresighter?? If so what was your luck with it and what brand did you use? Perez...hope you have many hours of fun with your 10/22.
