Begadi NPAS for (Army Armament, KJW, WE) HiCapa & 1911 GBB Series (CNC, stainless steel) -red-
The Begadi NPAS (Negative Pressure Adjustment System) is used to reduce the energy in GBB guns.
A side effect is the improved gas efficiency and less pronounced cooldown susceptibility.
Our NPAS valve consists of 3 components:
- Two-part stainless steel valve with thread
- PTFE washers to adjust the length and thus the energy
- CNC machined backplate made of 7075 aluminum
The valve in connection with the threaded cap was made of stainless steel CNC and replaces the original plastic valve in the nozzle.
It can be installed and used in many GBB weapons available on the market.
The washers included in the scope of delivery (PTFE - 2x 1mm, 1x 1.5mm) are used to adjust the valve.
The more washers are inserted between the valve and the threaded cap, the more the energy drops.
Compared to other systems with an O-ring available on the market, our valve does not move even at high energy levels. Because the length over the PTFE washers always remains the same.
If you want to lower the energy of your weapon further or adjust it more finely, it is also possible to use normal shim discs from AEGs.
Also included is an optional 7075 aluminum backplate.
This is much more robust than the original plastic part.
If your GBB has a nozzle with a steel pin, this backplate cannot and does not have to be used. The pin is much more durable than a built-in plastic backplate.
Our backplates are suitable for (tested):
- Army Armament R-Series (orange)
- WE G series (orange)
- KJW KP-13 (orange)
- Army Armament HiCapa series (R501, R601, TTI) - (red)
- WE HiCapa series (red)
- Marui HiCapa DOR (red)
We recommend installing the backplate for the weapons listed above.
If your weapon is compatible with one of the above, the corresponding aluminum backplate can also be installed here.
Scope of delivery:
- Valve with threaded cap made of stainless steel
- 2x PTFE washer with 1mm
- 1x PTFE washer with 1.5mm
- Backplate made of 7075 aluminum
- Screws
- Allen key
Please note that technical knowledge about GBBs is required for the installation.
Examples of energy: (Environment: 23 ° C, ProTech Balanced Gas, 0.20g BBs)
