How to properly HPA your GBB pistol! Gun in the video: KSC P226r / KWA P226 If you want to help me out and increase the video flow please like, comment, share and favorite. And ofc subscribe if you haven't already! ►►►This should work with any pistol. But in single stack magazine you will need the "Russian Tactical HPA Nozzle". Easier version: https://www.youtube.com/watch?v=x_eaXHlrnbc These numbers can change from pistol to pistol. 95 psi - lowest i cound go 0.20g - 94 m/s - 308 fps 0.25g - 83 m/s - 272 fps 120 psi - can go higher 0.20g - 103 m/s - 338 fps 0.25g - 92 m/s - 302 fps This would cost too much for me to do for you. It will take me at least 1-2 weeks to make one conversion and that is around 700 dollars in just work time, and then i will need the items + shipping cost as well. I believe it will cost around $1000 dollar, and it's not worth it. I made this "how to" video to help you guys. it's way better if you try it yourself instead of me making it for you. I have never asked for any money before, but this can actually be possible as a consumer product. You can help me out by donate any amount of money. Everything helps me. I am trying to save up for a 3D printer of good quality to make really fine parts. This does not only count for this project but for many more things that i have in mind for the future like all sorts of mounts for phones and action cameras, grenades and shotgun shells that prepells by powder, timegranades and alot more. Everything will be sold for a decent price.
