I have a 4x ACOG that is made to be used with a 14.5 barrel. I actually have a 16" barrel. How big of a deal is that?

Depends on your ammo. Using different ammo is a bigger problem than barrel length. Shooting very similar ammo, zeroing with that ammo, and knowing your points of impact will help.
what change, if any would I notice?
I shoot 55gr federal xm193
my range goes out to 600. They have targets from grapefruit size to man size.
I zero at 100 yards right on the dot of the reticle. I'll just give it a go I guess.
