Reflex 6 CPVC Skeleton Cylinder

thingiverse

This cylinder employs a stock rotation spindle that fits snugly into the print. The barrel length is designed to be 4" based on testing and plunger volume calculations. You can extend it for more fps, but likely at the cost of fps consistency due to variations in dart to barrel fit. 1/2" cpvc and 5/8"OD x 1/2"ID polycarb tubing will work well, offering a good friction fit that may require glue or sealant like superglue for added security. The base floor of the cylinder is 0.35mm longer than measured stock to enhance sealing with the plunger, but may hinder rotation slightly more. Be cautious of the center spacer, as it may detach from the rest of the base layerwise if printed upright, yet should remain stable once barrels are friction installed. Edit: A rearloading edition has been added.
