My opinion is to go with the Colt or M&P. They'll be more like the AR as far as controls like mag release & safety. And they have 30 round mags. I think the Ruger has only the standard 10 rnd mags like the normal 10/22.
Really? That stinks. Are they having funtion problems?
In that case maybe the 10/22 AR look alike is a better idea. Hmmm
