I'm relatvely new to firearms. This is the first rifle that I own, and have bought myself. Ruger 10/22 10rnd mag 25rnd mag scope mount 6 position stock extra stock Out of the box: With front rail cover off and TLR1 on: Now for the questions: This came with it, and I know that this is considered the extra stock. I like the angle of this one better, but can't figure out how to get the shoulder rest off of the other stock. Can anyone tell me how to do this? I've looked at it, and can't figure out how to get the position pin out in order to do the swap. What is a good ($50 or under) scope or sight that I could put on this. The Ruger manual said that it was fine to dry fire this rifle. I have always been told NEVER dry fire a rim fire weapon. What is your advice? How good of a deal, if any, did I get? It was $310 OTD.
