I got one of the lightweight Ruger's with the 20 inch barrel. I ordered a 3X9 Burris "compact" for it; It won't fit. I put a Leopould 3X9 on it but it looks huge on this small rifle. It looks like I'm going to need at least 5 inches between the flares for one to fit. Have any of you guy's found a small scope that will fit this rifle? I don't want to use the offset rings.
