Let's us now the velocity and accuracy !!!! Looks great . Is the gun now light removing the heavy aluminum 4500 psi tank and replacing with much lighter carbon fiber tank. Are you going to try any slugs?

I did similar to my Gauntlet .30 except i machined a tj .30 cal 1/26 twist 21" barrel, air stripper and added baffles in the remain space. Then added donnyfl. I put a 350cc carbon fiber bottle and tried 3 different regulators. Stock 2800 psi, ninja 3000 psi, ninja 3300psi. I also ported the the valve, transfer port and barrel port. Reworked trigger and springs. Gun sooo much better than from factory. Shoots pellets and nsa slugs lights out. Im hitting golf balls at 200yards regularly.

I'll be interested to hear how you like that adjustable regulator, I have the same one. How big a plenum do you have? I'm going to install mine on an Airforce Condor.
