Looking to purchase my first AR gun not sure what brand to buy. I've been looking at Bushmaster, Windham Arms, Rock River Arms, LWRC, Colt, and Troy. Does anybody have any suggestions for a first time buyer? I plan to use it for plinking and hunting coyotes. I want to put a good set of optics on it not sure what kind but I also want iron sights as well. I want a gun that if my life or may families depended on it will work everytime. I have a Hi Power that feel will work everytime I pick it up I want to feel the same way with my AR I purchase. Any suggestions?
