I installed a Vortex kit in one of my .177 HW30’s.  The shot cycle is smoother, faster & maybe even a bit quieter.  However, there was no change in muzzle velocity.  I’m still really happy with the kit and will eventually put the Vortek kit in my other rifles.  I’m not familiar with the mentioned o-ring tune.  Good Luck.
