uuhkeiy .. by bolding you mean adding a mesh and attaching it to the tag or smthn ?
I have tried
-attaching the tag to gun mesh
-moving the tag up
-rotating the tag
-renaming the tag
-made the tag renderable in game where it was seen where it should be
-compared it to the original disruptor one more time
-taking the completed gun and adding fresh tags
