Very hypothetically speaking, if someone were to want to get a new AR, what might be a good, reliable brand, and what caliber might be best? Oh, and I guess, which is the way to go? Direct Impingement or Gas Piston?
I`ve always just assumed that the .556 mm was the best, and really only way to go, but would the .308 be a decent option as far as ammo availability, cost, and functionality? and yes, the AR would be a rifle to defend against any and all threats whether social or governmental.
Last point-what might be a good quick-acquisition battle combat-sight? Is the ACOG still king of the hill?
