Yesterday I found a Ruger 10/22 carbine for 179 slightly used. I have no idea why I've held off buying one of these after shooting my brother in law's, but I have one on layaway. I already started looking at replacing the stock with a stock that has a pistol grip, and I'm gonna get a few hi-cap magazines. What would be a good replacement stock that won't break the bank, and what are the best hi-cap mags? Thanks in advance!
