NZ$37.75 and about a week later the N.P.A.S. arrived. • It was relatively easy to install but don't attempt this if it's your first time working on an Airsoft gun. • While the N.P.A.S. has brought the FPS down, it has come down a bit more than what I hoped. • For the chrono tests I used a freshly gassed (Green Gas) mag each time and 0.2 gram MadBull BBs. • For the Grouping test I again used a freshly gassed mag but 0.25 gram (no brand) BBs at 18 metres (about 60 feet). • Links • How the N.P.A.S. works • RA TECH HOW THE NPAS WORKS • Purchased from http://www.tokyo-model.com.hk/shop/ra... • KWA Kriss Vector bolt disassembly • KWA Kriss Vector Bolt Disassembly for... • Join me on Facebook www.facebook.com/CellusNZAirsoft • Find out more about Airsoft in New Zealand • Airsoft Sports New Zealand (ASNZ) www.asnz.co.nz • Taranaki Airsoft Rangers (TAR) www.tar.asnz.co.nz • • Filmed using an Olympus Stylus SZ-16 at 1080@50fps.
