Colt has not offered a AR15 in 308

The 308 Norma Mag is beyond a hunting rifle. It is more of an AMW. (Anti-Material-Weapon) or a very long range sniper rifle. If the rifle is in good shape and still has the standard wood stock and medium barrel, I would say it is worth $1,000.00 American dollars.
A 150 grain bullet shot from a 308 will start dropping the fraction of a second it leaves the barrel.
With serial 308, first year production 1952 will be date code stamped on the left side of barrel in front of receiver, check Remington society for chart. If IN 308, 1957.
Varies with barrel and cartridge, but the muzzle velocity is about 2600 feet per second.
