Agreed. I don’t hate the irons on the bolter but the way they recover to rest after firing makes the weapon very clunky in ADS. It should be high recoil, that’s fine, but it just wavers about oddly.
I made this topic linked above about the rack-sliding you mentioned, it affects numerous other magazine fed weapons (i.e. autoguns) not just bolters. Would love to see the animations changed and maybe even give us a proper partial reload mechanic, because it would make more sense and feel good mechanically too.
