I'm not trying to start a war or get flamed. I have a few myself and I can't decide which is my favorite. I lean toward my HK-91 becuase it feeds everything I give it and I also like where everything is located. I don't like the tight mag well and no bolt hold open device. I love the sights and the sub moa groups  that my M1A gives I don't like the small trigger guard the glass bed option. I think my favorite might end up being the AR-10(when it arrives)depedning on how reliable it is.What do you think,I'd like to hear your input, thanks.
