Prototype OEG gun site red dot mechanism. Currently it is in testing beta phase so if anyone wants to give it a independent shot here is the raw file. It is setup to use coil springs or rubber hose capped with a 1/4 bolt on the bottom/return side. The 2mm fiberoptic rod passes through the center hole from the light collection side to the ocular side and slides through 2 pegs that ride inside the adjustment holes allowing for a fixed up and down adjustment and a oval centered peg for your windage.
