M14 Fire Selector Replacement

thingiverse

I made this part specifically for my airsoft CYMA M14 EBR. Unlike most fire selector plates that come with it, mine is half metal, half plastic - the plastic component being the one I created. This piece fitted in perfectly without much of a problem (after several rounds of minor adjustments). I kept the screw holes smaller than those on the original (now measuring 1.75mm) so you can use smaller screws or tap your own holes at the right spot. I also ran a simple, rough stress test simulation to put this piece through its paces.
