Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4567835.

my redesign of the gb-22 by mark serbu.

the barrel goes/slides in first. the slide goes into the frame sideways via 2 slots. the slide is under pressure via a rubberband or other elasic to move the slide forward, and is connected to the frame.

uses minimal supports on the slide.
