How to play gun montage

Hello!
Thank you for your comment, fortunately I’ve achieved syncing the character to hold weapons and interact with them on the character skeleton, however I want to also work with the guns skeleton, for example when shooting, the sleeve should open and release a spawned bullet case (or a reload animation). The problem is that I do not know how to activate a gun animation (with its skeleton).

Might you have a clue? I was considering making an animation blueprints but have no idea if it’ll even work.

Thank you once again!
