I have the stainless Standard Model. It's not the first Ruger .22 I've owned but it's been a long time in between. I don't remember struggling with reassembly after cleaning like I struggled today! It's ready for the next trip to the range now. I ordered an adjustable sight from Brownell's and put it on today only to realize I can't use it with the front sight I have so I took it back off and will have to order a new front sight I guess. I've also been checking out the different receiver assemblies available and checked out the one Tactical Solutions had, Pac Lite I think. What do you all think of these? I want to mount either a red dot or a scope for punching holes in paper at the indoor range.
