Hey everyone I am thinking about buying my first AR and I'm not sure what I should do. My local gun store tried to sell me an m&p 15 for $800 but that rifle has no dust cover or push action thing on the bolt( sorry don't know all the terminology). I live in NY as well so the barrel looks weird because of the state rules. He also showed me a windham weaponry rifle with the dust cover and everything for $850. What should I do ? Any advice would be great! Thank you.
