Wildcat MK1 with Huma

When I changed my WC gen1 to a huma , I noticed shot string was tighter , and shot count was about same , but for me it ws a big upgrade as my FX regulator had issues with creeping , meaning when it sat first shots were lower ,I know it was probably leaking orings but I like the Huma regulators better and I have tester for them I didnt have the FX tester , and to use a gage with gun was not acceptable for me to adjust this way LOU
