THIS IS NOT A TOY!

YOU CAN BE SERIOUSLY INJURED BY THIS DESIGN, THE HOSING THAT CONNECTS THIS DESIGN, THE CO2 POWERING THIS DESIGN, OR ANY OTHER PART THAT MAY FAIL AT HIGH PSI AND I NOR THINGIVERSE ASSUME ANY RESPONSIBILITY FOR WHAT YOU DO TO YOURSELF OR ANYONE ELSE WITH THIS DESIGN. ALWAYS WEAR EYE PROTECTION, ALWAYS MAKE SURE YOUR PETS ARE SAFE!

Update 11-Dec-2019:
Converted to threaded inlet. Added M11x0.75 to 1/4" NPT adapter. Will add various other adapters soon. Makes it a lot easier to attach an air source to the inlet. Also adding piston dimensions for machining.


Update 05-09-2019:
Just realized the spring adjuster was not in the files. Whoops. There now.


Update 27-08-2019:
Increased thickness of walls on all pipes and increased rear support by 3mm. Also added 1mm of thickness to gas inlet area, and increased support there. (had breech explode at 1100 psi) [receiver_v5]
