I'm looking at getting a new 10/22 and wondering what the opinions are about the best configuration. I see the stainless carbine with synthetic stock is at Wallmart for a fair price. I think I'd rather have the 16" barrel, but don't know if an 18" would really be that different. They don't show the compact in stainless on the Ruger website. Also wonder if they are all drilled and tapped or will I need to take it to the gunsmith if I want to mount an optic?
