I already have a Armalite AR15 Flattop. I am looking at Bushmaster AR15 that just feels surperb and most likely it will be coming home with me. My Armalite has been flawless thus far. It very accurate and has never ever jamed with any type of .223 ammo including my handloads. I have read several threads that seem to think the AR15 made by Bushmaster is the best there is. I guess my question is the Bushmaster any better than the Armalite I already have? If it is what is it that makes it so?
