smudgelef Posted November 19, 2020 Share Posted November 19, 2020 Hey, I’m looking for an NPAS kit for my KSC/KWA Umarex HK417A2 so I can use it with full auto. It uses KWAs System 7 so I’m thinking it will be compatible with any system 7 NPAS but there Isn’t an exact one for my 417. Anyone have any tips or Knowledge on the fact? Cheers.

sjhirst Posted November 19, 2020 Share Posted November 19, 2020 milspecsolutions do a power down valve/npas set for kwa gbb's. They are for the mp7 and 9 but also fit other system 7 versions. They might be worth a look? I think these are what i fitted in my KWA AK many years ago. Link to comment Share on other sites More sharing options...

Just haven’t seen anyone or anywhere that can confirm. Worth the gamble tho. Link to comment Share on other sites More sharing options...
jsmithski Posted November 19, 2020 Share Posted November 19, 2020 If your replica has so called KWA rocket valve then it will work with the system 7 npas. Link to comment Share on other sites More sharing options...
