FX Fx amp reg brass piston reg creep? (Updated after polished)

It's mk2. So only 1 reg. As for polishing the washers, check this video. I copy what he did. Check at 12:40. He show how to polish the washers. I just copy what he did.
You are better off matching the washers in thickness so they all work equally, then polishing them a bit. Don't forget some real lube not silicon, synthetic motor oil won't explode in your gun under pressure.

I think it is just the nature of the beast with a regulated platform. If you have one that doesn’t ever creep at all I think you are in a very small minority group. Actually pretty impressive what those amp regs do. They are so small compared to many others. Little tiny things. lol.
Yes I believe the reg creep is due to its small size. I own a benjamin marauder and also the marauder pistol and installed huma regs in both guns. They never creep. I set to 2000psi. They will stay at 2000psi. But the reg for the marauder is like 5x the size of the fx amp reg. So I think due to the small size ppl are having problems with reg creep.
 
The Huma version doubles the surface area of the valve. It also refreshes nearly instantly. Very little to no creep. I rebuild the Amp regs weekly. The sentiment that they are too small is correct. Mostly in diameter than depth. A few more mm and thicker Belville washers would make a world of difference. And a more durable valve and face.
