With some weapon like FX-45 i shoot less than 50 times and it became ruin from worn state. For example guns like m4a1, KAS-74U became damaged after 1-2 full mags from worn state. Fun thing its suppressor only became worn from pristine, when FX-45 ruined. More guns can have durability like this and its need to be tweaked, because repair gun after 1-2 mag its strange.
