Or are you an AK fan? That is an even older design with only "minute of barn door" accuracy for all it's ruggedness.
M1's are good. But again, an older design. The SOCOM-II's are nice, but are not select fire, don't have to accuracy of the LR-308, and are hideously expensive in comparison. I could buy two LR's for the price of one SOCOM_II. Well, almost. Depends on optics. ;-)
Which is all tangential. Moot as well if the SCOTUS fails the Constitution again.
A Colt M4 is all I want.
I, personally, prefer the M1 Abrams, but will use the handheld in a pinch.
