Weapon mods - requirement for parameters to match (priority?).

[orangedeal]

I want to make Handmade rifle (Nuka) for the rounds 7.62 (default) and 5.56. They will have different barrels, receivers and muzzle brakes. But for the weapon to work, it must have all the components for the same caliber. So if you combine the barrel for 7.62 and receiver for 5.56, the gun will not work.

How can I do it in a simple way?
