Cost: ~€260
Since gas is temperature-dependent and can result in inconsistent shot performance, I decided to build an HPA system. Using an HPA setup provides very consistent shot performance and also allows you to play in winter, which is nearly impossible with gas. The only downside (or potential downside) is the hose connecting the tank to the magazine.
I sourced and ordered the parts from various shops.
Here’s a list of the parts I used in the order they are connected:
- HP tank
- Preset
- PPD tank adapter for pin valve (Adapter from Mamba hose also works)
- Male-to-male connector
- AKA Sidewinder
- Reducer 1/2″ to 3/8″
- Reducer 3/8″ to 1/8″
- Female-to-female connector
- Y-piece
- Mini pressure gauge (0–100 psi)
- 6mm Mamba hose
- PDP quick coupling (locks under pressure)
- PPD 1/8″ 90° compact elbow
- Thread reducer 1/4″ to 1/8″
- Tanaka 29-round magazine
Here’s a photo showing the arrangement of the parts:
I own three HP tanks. Two of them are 0.8L 3000 psi tanks, and the other one is a 0.128L 3000 psi tank.
To attach the hose to the magazine, I had to unscrew the valve from the base and drill a hole into the magazine bottom to cut a thread. Unfortunately, I misaligned the cut slightly and ended up having a 1/4″ thread cut and then added a thread adapter. I then installed an elbow fitting so the hose would run straight out the back.
I used a quick coupling that seals the hose and tank when the male connector is not plugged in.
I also installed a check valve into the fill nipple to prevent air from escaping the magazine when disconnecting the hose.
All fittings were sealed with Teflon tape.
A big thank-you to BigRed, who was a huge help!
There are now ready-made HPA systems available from the following provider.
