Muzzle climb is easier to control while moving with crosshairs than when prone using optics. Removing the scope in inventory helps as iron sights are less affected. This does not seem like intended behaviour as it is easier to run and gun than to use the weapon as intended.

Should be fairly obvious.
After more playing around with this I have discovered the problem. In optics mode mouse sensitivity is reduced making it slower to pull the barrel back down.
Not sure how this would be easily fixed. I think I will just +1 a "too many recoils" post.
