I’m a bit of a snob myself…but it always doesn’t hurt to get a second opinion. Anyone notice anything off about this rod? There is a VERY SLIGHT indentation on top which bugs me…thoughts?
FX experts…see anything weird?

its my understanding that damage to that part of the piston can cause creep. i think thats why their going to brass like huma. probably caused by going down slightly on reg or possibly simply a great deal of tuning.

Somebody tried turning the reg way down while the gun was pressurized. Must not have got the quarter turn then dry fire memo.

I can’t make out the indentation very well but Solo is right. That face represents the valve seat. Any imperfections can lead to pressure creep. There will always be an indentation developed as it breaks in but over time it will wear to the point where pressure creep will become ever more prevalent.

Huma isn’t all they crack up to be in my experience plus Huma can NOT be adjusted while under pressure while FX regulators can. I have a Huma on another gun and it permanently creeps if stored for a while so to say I’m disappointed is an understatement, plus their support isn’t helpful at all and won’t help me after multiple contacts and blame it on me. While FX send me a rebuild kit when I had just a oring problem. Call FX and the reg are actually cheaper than Huma rega, in fact the entire bottle adapter with the reg is cheaper than Huma reg alone. YMMV.

I agree with Qball, the Huma not best way to go. How old is your gun? It might be under warranty. If not, thats a cheep part from FX USA.

I'm definitely not an expert but, I ordered parts from FX to rebuild the original AMP in my M1 conversion because it was creeping. After the repair the creep was much worse and would not stop after shooting quite a few times. Ordered a Huma, installed it and have had no issues since. It adjusts the same as the AMP and so far no creep. The only thing I don't like about it is that it adjusts with a flat screwdriver rather than a hex key.

FX USA has brass pistons now all fx will use brass pistons now i got one just not having issues yet lol
pssss i never turn reg down under pressure degass

FX has them as a part you can order on their website? I will get them, this is a vast improvement. VetMX is 100% right, the AMP piston is supposed to be dome shaped. A dent is caused by lowering reg under pressure. You can raise pressure. Same with Huma. You can raise under pressure, not lower. I confirmed this with Huma. I talked to them in detail because of a creep issue also. Had this problem with all my Huma regs. Once I stopped trying to get higher pressures, anything over 135, I stopped getting reg creep. Huma IMHO just doesn't like higher pressures even with adding washers. This is a problem of course for slug shooters that need more speed. I like the AMP stuff, especially if you polish the two ends that meet to close the reg. The new brass piston will be a good improvement. Douger do you have a part number?

They work fine for years if you do a quarter turn then burn off a couple shots if lowering. 3 years and going on mine and never been apart and it doesn't creep.

Oh shoot…yeah this is nice if true. The only reason I wanted a huma was because of the brass regulator rod…but if they have them now and for less…then it’s worth it.

Yeah see I had leaking issues with my impact…and they went away after installing a Huma. This was the pre-AMP regulator Impact (MK1) though. Décisions…décisions.

that!!! I usually do 1/8 of a turn when lowering reg pressure as it is pretty sensitive at higher pressure ranges anyways. Upvote 0
Yep. It’s a second hand dreamline I got from the forum. Ordering an AMP from FX tomorrow morning

this!!! and applies to every Reg.I am amazed ppl buying new and new and new tricks expecting to work a magic....Fix it, or ask for training
When you polish the mating faces in between two pieces you don't do it in 3 minutes....do it in 5 or 10 if needed redo four times.
