The various muzzle enhancements can not work together, so it says in wiki and when you try to craft.
But I currently sport a silenced muzzled 5mm jaguar that I crafted myself, without problem.
The compensator also work with the silencer. However, the compensator and muzzler do not work together, so the mechanic is in place.
So this is either a bug, or the wiki is obsolete regarding the silencer.
