What is everyones opinion on what is the best carbine semi-auto rifle that is not an AR or AK? I am thinking about purchasing a new rifle once all the prices go back down, but i want something that is gas-piston operated. I really dont want a gas-piston AR because the gun was not designed around that operating system. And because i already have an AR.(I like varitey ) And i dont want an AK either. I just dont like them that much. What do you all think?
