ASG/KWA MP9 help

[james123]

I have a second hand asg mp9 on the way which comes installed with power down flute valves, i was wondering if there was anywhere i could source stock flute valves, to re increase the fps of the gun, preferably in the uk. Thanks in advance

It will likely be over the legal limit if you do, or at the least site limits

Don’t think you’ll find a stock one in the UK, plenty of HK retailers will have them though. 
As rocketdogbert said it will most likely be over UK limits on standard green gas, I have an upgraded WiiTech nozzle in mine and need to use 134a to get it under 350fps. 
 

The new Vorsk VP1 *may* have the same system as the MP9, so maybe a nozzle from that will be compatible….
