Airsoft AEG M4 Updated Selector Plate (Fixes G&P)

thingiverse

G&P Airsoft M4 has a design flaw which causes constant problems switching between SEMI/FULL. Trigger will jam going into FULL. The problem is that the selector plate is too thin, and is bring pushed out by the sector gear bearing, which doesn't sit flush with the outside of the gearbox. This is a version 2 gearbox with 8mm bearings. This is a new selector plate which is twice as thick as the original, with additional cutouts for the bearings. The thickness allows it to make contact with the inside of the receiver, so that it can't bend outwards under tension and slip off of the cutoff lever (the reason the FA mode jams). Selector plate may fit other M4 brands, depending on receiver dimensions. Printed with auto supports, no raft, in FlashPrint. ABS, Temp 230, high resolution. The only supports are under the bearing cutouts, and beveled edge. Be careful with the spring guide pin at the top, it's very small and fragile! Use a razor blade to carefully clean under it so the spring will slide over it. I have this installed in my M4 now and it works beautifully.
