What should i do about my Ruger 10 22?

Why do anything to it? The bull barrel isn't really necessary because you aren't going to use it for competition or anything. The bull barrel is really only necessary on center fire rifles that can build up heat very quickly and become less accurate. A bigger barrel is not a big deal on a .22 especially if you plan on carrying it very far. That bbl will add a solid pound or so to the overall weight which will really hurt when packing it around for a couple hours. My suggestion for an improvement would be the extended mag release because i always used to fumble with mine and drop the mag out on the ground. Other than that, it looks like you are set up pretty well for your intended purpose.
