I just bought the ruger american rem bolt action .223 rifle and am looking to do some customeizeing but am haveing some issues with it. I'm trying to mount a scope on it but for some reason I can't get it to mount on due to the size of the rail. The same issue happens with the scope I use for my .22. Does anyone know what type of scopes fit onto this rifle? Also I'm thinking of adding a bi-pod is it legal to do so if so what kind fits this brand of rifle?
