How would i go about making parts visible to all players except local?

So basically i understand one way to do it, but that's "performance" heavy, Im using filtering enabled so that can be another problem, so i was thinking if there was another way, and if not, would mine work?

My idea was to do so:

Insert a global table (_G.Guns = {}), Use that table to announce the current gun each player is using, by using the player name, then gun in the table, Then making a script * have to request to server, then to client* so SERVER > CLIENT* saying: Weld this gun to this players head, then put in the local players camera. Which could actually cause problems but would this work? or is there a easy'er way.
