I've had a AR 9mm pistol and AR 45cal rifle, both were alot of fun to play with. After I purchased a Beretta CX4 Storm in 9mm (when they first hit the market) I sold the two AR's. I built both with Superior Arms upper and lowers and all the extra toys on them. I like to build an AR pistol in 7.62x39, but haven't because there is a lack of reliable mags that hold and shoot above 8-10 rds. Although the Mini 30 does now have Promag brand 30 round mags, I doubt they will work in an AR.
Being that your in Idaho, I bit you shoot your sure of spuds for target practice
