Airsoft Steyr AUG rail kit + micro switch trigger

thingiverse

The airsoft rail kit is specifically designed for use with GFG49 style AUG, requiring some hardware to secure it properly. On top, you'll need an M5x10 screw, while on the side, you'll require both an M4x25 and an M4 nut. When it comes to the barrel, any aftermarker airsoft 18.4mm OD barrel extension can be used, or you can opt for a printed one. You can then attach a 14mm clockwise or counter-clockwise flash hider to the printed extension by screwing it in place. The barrel extension itself can be either screwed or glued onto the rail piece. I personally chose to use CA super glue for a secure hold. For the micro switch board, you'll need to have a DC3 micro switch (measuring 20x9x6.5mm) on hand. This requires two M2x14mm screws and two M2 nuts to keep it in place securely. Alternatively, you can simply glue it in for an easier setup. However, using screws allows for easier adjustments down the line. To mount the board to the body, you'll need M3x10 screws. For adjusting the trigger pull, you'll require both an M3x15 and an M3x6mm screw.
