## About The Pull Request
The gun code is an absolute mess that seems to have been untouched for
the better part of the decade and finally gave way due to the attack
chain refactor. This PR is the first in my attempts to refactor this
mess by making bayonet attachment a component instead of /obj/item/gun
variables. Followup PRs may or may not be atomic changes or a monolith
due to how horribly the original code is structured.
## Why It's Good For The Game
Gun code is ancient, unmaintained, barely readable and started actively
breaking in the past weeks.
## Changelog
🆑
refactor: Bayonet attachment is now a component.
