My AR15 is easy to convert to a single shot....I only load one round into the magazine. I haven't figured out how convert most single shot rifles to semi-auto yet!

For the non-gun types that want a gun, learn how to shoot with Ruger 10/22 and a Ruger Mk III, then get a 30-30 lever action, 870 Remington shotgun, or a 4" S&W .357 revolver.
