G&G M4 (Combat Machine) Stub for Butstock

thingiverse

I designed a custom plug to cover the area behind my airsoft M4's stock, specifically for the G&G Raider model, as a replacement for the standard butstock. The plug features an inside diameter of 38mm and a square inside diameter of 13mm, with a total length of 34mm. To secure the plug in place, I added a 2-meter screw hole positioned 7mm from the internal stop, allowing me to attach it to an existing hole in the stock tube, which is a standard feature on the Raider model. I chose this unusual 2mm size because I'm using a 4mm screw that directly screws into the plastic itself, eliminating the need for a nut. The plug was printed with ABS material at 100% infill density.
