With the silencer installed,the trajectory dropped by 40cm at 50 yards, has everyone ever been in this situation?
Agree that this seems like way too much. On the Red Wolf, the different mods I tried were only different by a few inches. On my old impact, heavier mods could cause as much as a 6” drop, but I haven’t seen that much with the Red Wolf. The weight of the Ronin pulling the barrel down even more is the one reason I have never tried it.
If your group drops without changing size then it's the moderator's weight, if your POI drops and your group opened to a shotgun pattern then that is usually clipping. 40cm drop at 50 yards or 2 mils drop isn't unusual at all with free-floating barrel and heavy moderator.
