Sorry guys I know this topic of the reg creep have been discussed many times. But this drives me crazy that it's still doing it after buying the brand new brass piston and it still does it. Everyone knows fx amps reg is prone to reg creep cause they used a plastic piston. So I ordered the new brass piston and installed in my impact mk2 and find out I'm still getting reg creep. I set reg to 145 bar. Shooting 36gr nsa slugs at 960-970 fps. Let the gun settle down for the night. Check and reg went up to 155 bar. I think might be the gauge not accurate so swap gauge from bottle and place in the reg port. Using wika qauges, not fx gauges. Still climbing from 145 to 155 bar over a few hours. So got chorny out to test what the first shot is. I find out first shot is shooting 36gr nsa at 870 fps. I was like that can't be. Shot the 2nd shot and it climb to 940 fps. Then 3rd shot climb to 960fps. 4th and upper shots settle in 960-970 fps. That's about 100 fps from 1st shot to when it settle down. This is unacceptable imo. For a 2k gun. I thought buying this new brass piston will fix the problem but still doesn't. Most guys will just say, well dry fired 2-3 shots. But when you out hunting you cant afford to fire any shots and scared away what you are hunting. I watch a lot of Matt dubber videos and he seem to be really knowledgeable on the impact but never have he mentioned anything about the impact having reg creep problems. Smh. Anyone else getting reg creep with the new brass piston?
