TF2 Force A Nature (Nerf silly shell blaster)

If you want to buy me a coffee :) https://buymeacoffee.com/methanejuice

Update Note: 

20251106

Update Main Body_Core_V3 with additional tolerance so that the swivel won't be as stiff

20251104

Update GasSwivel to V3 to improve sealing previously 1.5mm too low

Added sling point as a variant (Stock_CLB_V2_Sling)

____________________________________________________________________________________________________________________________

The usual eal barrel lock is a switcher in this case. Switch left for left barrel and right right. The button in front of the trigger guard is the barrel release and will eject the shells. I really like the FoamANature by ehdrien, thought I'd give it a try
