Limited to 7.62x51 NATO. And a semi-auto rifle – no bolt action. I carried, qualified with, and cleaned the M16 for 11 years, and I never liked it, so I’m not looking for an AR chambered in 7.62 I know there are other long range cartridges like the 338 Lapua, but I want to stick with 7.62 NATO. If someone wanted a rifle in this caliber to potentially engage targets out to 800 - 900 meters in a post disaster situation, which would be your choice:
Springfield Armory M21 tactical
FN FNAR w/20" barrel
Browning Safari in .308
