That's the equivalent of saying a Honda Accord with 10k miles on the odometer should be the same price as one with 110k miles. It's gonna be fine till at least 200k miles anyway. but I'll take the one with 190k miles of life on it everything else being equal.
i guess i am under the assumption that you know the price before getting to interested.
my post strictly refered to round count and its effect on the gun.
a caliber like the 6.5x284 can see extream accuracy losses after as little as 1000rds. there for a gun with 900 rounds threw it is worth alot less due to the fact that very soon you will need to rebarrel it.
a glock with 900 rds threw it is worth the same as any used glock because its just getting broke in.
as my earlier post reflected some guns rd count is more important than others
