Airsoft M203 barrel latch

thingiverse

I broke my M203's barrel latch, so I came up with a replacement design. It won't withstand rough handling, but it will do for me. If your model of M203 has enough space, I'd recommend adding extra reinforcement to the hook. Use thick walls and 100% infill. Supports are required. Depending on your pin, the pivot hole might be snug. Print the part with the hole facing downwards, on its side; it should print as a vertical column.
