I found a minor bug in the sight zeroing of the M63A Stoner LMG and the M63A Stoner Commando that were released with the Version 1.1 update.
Basically only the closest range zeroing seems to be correct, but all of the other rages zeroing seems to be very off (I need to use 800 meter zeroing to hit a target at 500 meters away)
