playing game,and you killed a enemy,he has a very good optics(especially king of the hill,DayZ like mods,Battle Royale,or any pvp missions,if situation is urgent,and in DayZ like mods and Battle Royale,every already loaded mags are important but now,it takes long time to take them).
for now to get em's attachment.
1.access enemy's gear,and grap the gun.
2.then,your weapon will be dropped on the ground.(automatically your mags,grenede shells will be droped.)
3.detach optics from the weapon and drag it to your vest or ground.
4.get your weapon,and ammo,shells.
5.change optics.
very complex...
If make can access weapon like uniform by double clicking,just grap optics only,no need to grap the weapon
