It is not at all difficult to acquire a short range target with the ACOG.I want to try an ACOG but it might be overkill and there might be something much more practical that I didn't know about, and that I don't have to drop $1500 on it lol. Like with an ACOG is it pointless or more difficult to quickly acquire a short rage target?
If you want the ability to engage beyond a hundred yards, the ACOG is great.
If you never want to shoot beyond a 100 yards, then a red dot will do the trick.
