AirVenturi Avenger dual regulator/bottle setup with regulator adapter and block off for upper tube.
This kit is machined from 7075 high strength aluminum. It add an upstream regulator (not included) to the Avenger which is fit to an air tank of your choice. This dual regulator setup is what some high end airguns use and provides insanely tight shot speeds. My own Avenger .25 shots a slug at 1029 FPS (highly modified) every single time. When properly setup this will provide ultra low SD's and take some of the strain off of the stock Avenger regulator.
This includes a regulator adapter and a plug for the upper tube location. You will need to purchase a paint ball style regulator which is set 300 - 1000 PSI higher than your set pressure on your stock Avenger regulator.
Do Not Use Air Ninja regulators for output pressures above 2,800 PSI. There are not enough thread on the bonnet to hold pressures over 2,800 PSI safely. Chinese regulators have 2 extra threads and can hold to 3,000 PSI output pressure safely.
