The best way to downgrade an ASG MP9 A1

[JonSut]

Hi I have recently come by an ASG MP9 A1 and want to know the best way to reduce he fps.

should I get the downgrade bolt which reduces power by 30-50fps gas dependent. 

Or

the NPAS valve kit or LPE valve kit.

I am fairly tech capable and not daunted by some technical tinkering.

advice and links please.

TIA

I bought this for my kwa mp9

And how hard or easy are they to install?? Have you any YouTube links?

pretty simple to do just time consuming

take bolt out of the gun and there basicly just pins that hold the nozzle in

start at the back of the bolt theres a long 2/3mm pin punch it out there will be a small spring that holds that metal flap under tension do not loose it

 just by the nozzle there two smaller pins each side punch them out and nozzle should slide out they are different lengths of pin so need to go back in the right hole

just take your time it pretty simple

I installed the WII tech nozzle and piston base at the same time which is defo  worth having a look at makes the recoil and shots a lot sharper and snappier

there is a youtube video but cant memba what was called

you cant fit one with out the other as the kwa stuff wont fit

and I had to modify the nozzle to get the power below 350 as was shooting 380

even increases the rate of fire not that u need that lol

give me a pm if you get stuck buddy
