I've been debating getting a .308 for some long distance plinking. Nothing to strenuous and for reliability/durability the only semi-auto .308 I really trust are the M14 and the FAL. Now I could go buy a slicked up M14 but thats just not exciting me. AT ALL. So I'm heavily leaning on the SA58 and I wondered with that 21" barrel, what kind of range/accuracy can be expected?
