The topic says it all. Opinions on this rifle please? I have a 182 series Mini 14 and decided that I "need" a more accurate rifle that is suitable for mounting a red dot sight on. My son will take over the Mini. I looked at the S&W M&P and the Colt, and found myself drawn to the Ruger. The piston design is said to be superior also. All opinions appreciated. All advice welcome although not always taken.
