JonSut Posted April 24, 2017 Share Posted April 24, 2017 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 Link to comment Share on other sites More sharing options...

JonSut Posted April 25, 2017 Author Share Posted April 25, 2017 And how hard or easy are they to install?? Have you any YouTube links? Link to comment Share on other sites More sharing options...
alex90 Posted April 26, 2017 Share Posted April 26, 2017 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 Link to comment Share on other sites More sharing options...

alex90 Posted April 26, 2017 Share Posted April 26, 2017 I fitted this parts at same time I got them from ebay at the time as was a uk seller and didn't want to wait https://www.uncompany.com/pageproductdetails.asp?prodid=31820 https://www.uncompany.com/pageproductdetails.asp?prodid=32903 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 Link to comment Share on other sites More sharing options...
