So I need some schooling in AR/AK Pistols, whats the purpose? I tried shooting one and found it cumbersome and wanted to put the Sig brace to my shoulder. Of course that being against the law, i refrained Anyways, everyone i seen without the brace shoots from the hip, which i don't find safe or accurate at all unless your a being a bad$%& with a shotgun. Can someone tell me the benefits of it besides you don't need a tax stamp for a SBR? Not knocking it, just asking?
