Tuning Need help

[sanjay n]

Hello every one, my M3 700mm .22 first reg is taking a lot of time to recover back to the set pressure ie 165B so i saw a youtube tutorial and polished the washers and the regulator adjuster but still i am facing the same issue and my spring washer stack is rearranged but my reg adjustment has become super sensitive after polishing 1/4 turn brings it from 100 to 200B need help resolving this issue, also plannig to order 1st and 2nd reg from huma air if the problem persists,
TIA

How old is your M3? Do you have the brass pistons? The brass pistons may be available under warranty. Call FX USA or FX that serves your country, they are very willing to help.
The brass pistons have helped in many cases.

On the age thing, it's possible that you have bad washers or the wrong stack, or the wrong sequence on the stack | )()()()()(). As long as you have it apart replace the o-rings. The FX AMP regs work just fine, once you do a touch of TLC on them

+1, oring replacement does wonders on the AMP regs.

Also, pass a strand of copper wire through the tiny air orifices. There may be a bit of something lodged in the air path.

I tried this kind of stacking but unfortunately the reg did not respond it was not taking any air inside it was stuck at 0 bar even after screwing the bottle but the bottle pressure was at 200 and the bottle pressure gauge was working really fine

I had something similar, absolutely couldn't get any pressure above 60bar on #2, tore the regs out, took out the #2 gage, blew air every which way, reassembled and nada, got some new brass pistons and housings from FX under warrenty, played with the washers and boom, pressure. As long as you're tearing things apart you could change the valve seat and valve, heck who knows. Or save yourself yourself some anguish and let FX fix it. I just had a thought, how far out is Hammer Spring Adjuster if the M3 has one. FX spec is 19.3mm over all length on the Maverick,
