Looking for opinions/insights/observations from those who have experience shooting or owning semi auto "battle" rifles that aren't ARs. What do you like about them, what do they do that an AR doesn't, accuracy, robustness, would you rather have the non-AR if you could only have one, etc. I know there are folks who will never, no matter what, ever have anything except an AR. I love ARs also, but I'm looking for some robust, reliable, and accurate alternatives.
