I got my stage 6 full pooty core last Monday, fit the orings(highly recommend you do this), gassed it up to make sure there was no leaks and took it out this past Saturday and it shot like a beast... This is my second pooty core I have it on both my 1.5 @ 2.0. I'll post my video of shooting it.
Just remember to fit your orings and remove the feather touch screw. If you don't remove it all you'll get is a puff and no shot.
