What’s really annoying to me is when you either find a weapon with an attachment or you put one of an existing weapon then later when you want to research said attachment you can’t even take it off the gun! I guess you can blame it for being alpha but what would stop facepunch from implementing this option?!
No reason to. The ability to remove attachments means that you can save a massive amount of metal as you upgrade your weapons, as well as research upgrades much faster by borrowing/stealing other players kits. The attachments are already very easy to find so I see no reason to do this.
