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

thingiverse

G&P Airsoft M4 suffers from a design flaw that causes frequent issues when switching between SEMI and FULL modes. The trigger gets stuck going into FULL mode due to a selector plate that is too thin, causing it to be pushed out by the sector gear bearing. This gearbox has 8mm bearings in version 2. A new selector plate has been designed, twice as thick as the original, with additional cutouts for the bearings. Its thickness allows it to make contact with the inside of the receiver, preventing bending and slipping off the cutoff lever, which causes FA mode jams. This selector plate may fit other M4 brands depending on receiver dimensions. It was printed with auto supports in FlashPrint without a raft at 230 degrees Celsius and high resolution. The only supports are under the bearing cutouts and beveled edges. Be cautious when handling the spring guide pin at the top, as it is very small and fragile. Use a razor blade to carefully clean under it so the spring can slide over it smoothly. This upgrade has worked flawlessly in my M4.
