Mounted gun upgrades

So I’m building a mobile looting base, something I’ve done plenty of times, however I’ve never mounted a gun before.

I’ve got a nice M60 that’s undamaged, I was wondering if accessories (brass catcher, etc.) and general upgrades (silencers, accurizing, etc.) are still applied once it’s mounted?


It may change relatively soon, but at the moment mods are just deleted from the gun when it’s installed.
