Erica Chen, (RA-Tech) have sent over a video of their “negative adjust system”:

Dear Arnie, Good day.

We have got new product, the negative pressure system, and we have done the new test video for it last night.

It is unique design based on Bernoulli’s principle, and it could solve the problem for "pissing shot" and "double feeding" as well,

and the more important is that it could provide the function to adjust the FPS and blow back’s power, too. Please go check our video at YouTube as the link below.

Best regards, Erica Chen, (RA-Tech)
