I designed this de-pinger and spacer to take the ping out of my son's AEA Challenger .30 bullpup.
The depinger must be printed solid/100% infill. The spacer keeps it 150mm above the valve. I printed this in PETG material for toughness.
Printers vary so be sure both parts fit in the tube just slightly snug. You need to resize in your slicer and reprint if not.
Installation...
1- Degass the gun by backing the gauge out until the air leaks out.
2- Unscrew the air tube cap that the gauge is in.
3- Put the spacer in, put the de-pinger in next then push them down the tube carefully until they stop.
4- Reassemble in reverse order.
5- Cock the gun and put the safety on to keep the valve closed when airing up from empty, otherwise air will go out the barrel without building pressure.
