HPA tank buttstock (airsoft)

3D printed buttstock for your HPA bottle use in combinations with tank stock setups like Novritsch SSX10 and wolverine wrait/unleashed setups fits bottles up to 51 mm diameter. All my own different brands of 0.2 and 0.14 bottles fit perfect with locking mechanisme to install your bottle firm inside the buttstock comes with extra tape to adjust for smaller diameter bottle should you have a larger diameter bottle, let me know so I can change the design for you
