Animation bug with model and player

Hello devs!
I was trying make system which adding model to player and play animation but i got strange bug.


Animation playing on player but not on gun, and when i touch the other player animation start wotk with gun.
Animation made in roblox animation editor and haas a max priority

Maybe it has something to do with the tool grip position.

Its not tool, its model welded by motor6d to the player head
