That'll also be a problem since the .50 cal has shitty accuracy in general. Worst sniper in the game when you add the fact that it's accuracy is coupled with
ridiculous kickback. If you actually saw someone say it's a good gun to use, you can tell them I said they're borderline insane and have no idea what they're talking about. Never listen to those people again.
But if you really want to use it, it'll be easier if you don't use it from very long range. In which case, the ACOG is your friend.
Edit:
..and no amount of lag in the world is going to stop you from hitting a non-moving target. So in this case, it's either you or the gun.
