The Crossbows, blunderbuss, and Hunting rifle (all single shot, auto reload weapons) when fired from ADS mode, lock you into ADS mode, if you dont want to be locked into that you have to cancel the animation.
It can become disorientating, and hinders normal movement and view, especially with a scope equipped.
MM had said he made a ticket to see if we could get the option to disable auto-ADS. I dont know if that worked out, but the single fire weapons I think should be tested a bit if you dont already know what I mean.
From a balancing perspective these weapons are already not the most preferred, the added awkwardness to combat this causes I believe should be looked at.
A potential fix would be either a menu option to disable all auto-ADS, or like we used to have, tap RMB to auto-ADS, hold RMB for only manual-ADS with no lock in.
