I am considering uppers for an AR build, and my question is this: How limited is a 16" barrel on longer range shots (say 500 yards)? With all else being equal - same quality ammo, 1/7 twist crome lined barrels, use of optics so sight radius is out of the equation, shot from a bench, etc.
I am leaning towards a mid length 16" upper, but I don't want to limit myself if I want to take the occasional long shot at paper. My understanding is that the real differences here is the lower muzzle velocity of the shorter barrel, which means the bullet goes sub-sonic faster, and the bullet will be more susceptable to wind drift. How much practical effect of this will be discernable at 300, 400, 500 yards as between the two barrel lengths with the same ammo? How many people here take shots like that with a 16" rifle?
I would like the smaller package offered by the 16" barrel, but I don't want to be unhappy with my descision in the mean time because of range limitations.
Thanks in advance for any thoughts
