Uh oh, looks like sniper dosen't want to carry weapons.

Hmmm that shouldn’t be a thing. Are you using an addon tf2 ragdoll and not the default rag dolls?

[north comet]

yeah

yeah i just checked, it works on the standard and HWM models

Run the game with -noworkshop -noaddons to see if it’s an addon issue in the first place

If the problem goes away then you know an addon caused it, and need to find which one

Alternatively try copying the model link for the sniper model, and run whereis model/link.mdl in your console. This will tell you which addon is overriding the default model.
