Silenced Code Optimization:

[yzdjmm-unturned]

I'd wanna to make a subsonic bullet magazine (firing with the magazine loaded won't alarm zombies and animals, but the Silenced code seems to only work on barrel fittings, could it be changed to support this code for all attachments?) ）

Similarly to #5006, you're right that some of these properties are barrel-specified. If improving attachments to support custom attachment slots it would make sense to allow all properties to be configured on all attachment types. One of the main reasons for these properties being silencer specific is deciding how to handle prioritization/combination of conflicting properties (e.g. a gunshot override on the barrel and on the magazine).
