Firewad Panther HPA Tank Buttstock adapter

Some time ago, I posted this on Firewad's Discord. I think it's better to have it here so it doesn't get lost among the old messages.

This model allows you to mount your HPA tank on your Firewad Panther Kit as a buttstock.

The model ‘grabs’ the regulator so that you only have to screw on the tank and connect the hose to the mag.

In case your reg's QD fitting nut is not "flat", you'll need spacers. I printed those in TPU for squeezingess. My QD was almost flat and 1mm thick spacers were enough. If you need them thicker, just resize Z axis on your slicer

Several rear pieces are included depending on whether you have a short stroke in your AAP.

There are also 2 extra adapters inlcuded that allows you to mount any standard picatinny or buffer tube stock without changing the whole rear piece

Updates:

• 26 Nov
  Several variations with larger holes have been added to accommodate regulators with slight variations in size. Versions with holes 0.5 mm, 1 mm, and 1.5 mm larger have been added.
  Quick-print parts have also been added so you can check which size best suits your regulator.
