Hiya guys, 

Im Steve that runs the Precision Airgunning group on Facebook. Feel free to join.

Some of you may know me from some of the groups, I specialise in long range precision shooting with powder burners and also airguns. I currently run a FX Impact .25 cal shooting the incredible Zan slugs. I also specialise in Gun/air smiting and carry out various tuning, repair/improvements/modifications and have come up with my own solution and procedure to cure and rectify the dreaded regulator creep on the AMP regulator found on various FX airguns.

Feel free to join Precision Airgunning on Facebook, and also subscribe to my YouTube channel for future content including long range airgun hunting, long range target shooting including my Impact shooting the Zan slugs at sub 1" at 200 yards! plus much more.



Many thanks guys and best wishes.

All this makes sense. I do have a couple of questions:

1. Shouldn't the parts be cleaned after polishing to remove any abrasive residue or dirt on them?

2. Is everything assembled dry or is any kind of O ring lube applied?

Thanks.

hiya matey, 

yes I do give the air holes a blow out with compressed air, and i also give the parts a through clean before assembly.

I also give the Spring washers a light smear of grease before assembly also .



many thank

Thanks for a very informative video Steve. Perfect timing almost as I just pulled the regulator out of my Crown today and did a quick down and dirty reseal that fixed the venting from the small hole on the side of the action block. When I get more time and some of that nifty 3M polishing paper I'll do it the right way.

Can anyone confirm that this is the polishing paper to use?

3M Tri-M-ITE Wet Dry Polishing Abrasive Paper 400-8,000 A/O Assorted 6 Sheets (2E) https://www.amazon.com/dp/B07CP9CCH4/ref=cm_sw_r_cp_api_glt_i_PKG427CV1F2DBFH64SQ0

Yes mate, as someone else suggests this is the correct papers.

it’s good that there is also another 1-2 videos on this subject but all of them seem to have a few important steps missing which is critical for best regulator performance.



Let us know how you get on.

Need help…

I just did this polish to my regulator. Seemed to go well. I put everything back together carefully. Started screwing the tank back on the gun, started to pressurize nicely, the first reg gauge was climbing and then there was a small pop and air started hissing out the hole on the right side of the block where the angled gauge mount would go if I had one (I don’t have one). One thing to note in case it matters, but I don’t see why it would… I took the second regulator gauge off the back underside of the gun to blow out the regulator piston as per the instructions by AOA. I was able to remove that gauge by hand, no tools. When I got it out I was surprised to find it did not have an o-ring, and instead was sealed with something that was relatively clear and had hardened up. When I re-installed the gauge I screwed it back on hand tight. I kind of expected I might get a leak around it, but I didn’t. At least not before I started loosing air out the other hole. What happened?

Update for other who might try this…

First off the second reg gauge didn’t have an o ring per-say, but it did have a rubber seal I didn’t see. Figuring my problem had to have something to do with my reg install I took it all back apart. I found that the seal on the reg piston was blown. I thought I had been careful not to over tighten the reg body, because that was stressed in an AOA video, but decided that was what I must have done. I happened to have a replacement o ring so I replaced it and put everything back together, being very careful not to over tighten the reg body. I then went to install the trigger and it was a little difficult to get it installed and when I did get the pen in the trigger would not move at all totally dead. That same thing had happened once the first time I installed the regulator so I kept trying but kept getting the dead trigger. So I started examining to try to figure out what was going on, and I it appeared the trigger plate was hitting the reg body so to test I removed the reg and installed the trigger without it and sure enough the trigger was easy to install and worked fine. So it turns out that the original problem was not that over tightened the regulator body, but that I under tightened it. I got it all back together and it seems to operate normally now.
