Taiwan 2012 HOOHA SHOW PART 4/4 - YouTube
It's RA-Tech design
alumionium nozzle is a definitely want, but the way it set fps reminds me of WA style NPAS which was prone to self adjust due to recoil causing the fps to go down (even if you change mags) the only fix was use loctite, but that would remove the npas capability.
I really hope the nozzle is in an affordable price range. The WE steel bolt carrier was hopefully it is too. (WA system had the bolt carrier at $120 -Typical highend in WA, and $140 (not a typo) for the nozzle. The nozzle being at such a high price was a deal murderer.
I'm hoping the price would be around $30-50. $30 for a cast&CNC design $50 for billet CNC. I understand the main cost is the CNC (there's probably atleast 50 programmed steps in the cnc process.
