Rock River now makes a complete left handed rifle. I am in the same boat. I shoot rifles/shotguns left handed and pistols right handed. I am trying to retrain myself to shoot everything on the right side. I am actually right eye dominate but, started shooting lefty as a kid because that's what my Dad did. I am looking at my first AR, but will buy a righty so my wife and son can shoot it as well. I have never had an issue shooting a semi auto (shotgun, 10/22, etc.) righty.
