Tuning M3 Has To Go Back...

call them ..they might send u the part.

all the best

Sorry man. As @tibor said, give them a call and see what they can do as far as sending you a rebuild kit.

That's too bad.

I may have the same problem though.

When I received my M3 compact, my first regulator read the bottle pressure. It went down to 150 bar after I shot it a few times.

BUT, when I leave it for a day or so, the first reg pressure is up over 200 bar and when shooting goes below 150 bar to around 130 and stays there during the shooting.

Might have to call FX myself.

Please post again when you figure it out. I thought the M3 I got from Ken Hicks this week had an issue with the first reg, but after thinking about it, all is fine. I will preface by saying neither of my regulators has creep, have had no problem returning to set point, have never released air, and I have not adjusted anything. The gun came with a report stating the first reg was set at 200 and the second reg set at 150. I shot the gun down to 150 bar in the bottle. The bottle and reg gauge showed 150 bar-the same, of course. How can the first reg show the 200 bar Ken set it at, when the bottle can only supply 150 bar? I filled the gun to 200 bar and the bottle gauge and first reg showed the same 200 bar, again, of course. I filled the bottle more, to 225 bar. Now, the bottle shows the 225 bar, the first reg is rock solid on 200 bar, and the second reg rock solid on 150 bar. With any bottle fill/pressure of 200 bar or less, the and bottle and first reg will show the same. I hope FX gets yours fixed quickly.

Same thing happened to mine. Got it fixed up, but was disappointed that it was less than 4 weeks after I got it. I don't have a high opinion of the front reg in the M3

That is a bummer, but I'm sure a resolution will be obtained.

Will

I would think they could turn that repair around in a couple days if their repair department isn't backlogged.

1st regulator on my M3 isn't the most consistent thing either... When shooting sometimes it drops a bit low then after a couple shots goes back to the set point, and if the rifle sits overnight it likes to creep up 20 bar or so over the set point.

However, velocity/ES/SD on the chronograph is always right on and very consistent so the second regulator is doing its job perfectly. I just want the 1st regulator to be a little more consistent.

At some point I'll pull the first regulator and polish the sealing surfaces, inspect the belleville washers, and relube the o rings with molykote; simple enough job. I just need to do it before it decides to go sideways on me while out hunting.

After squirrel season I might send my M3 back for a new lower action block, or try to get them to send me a new one and I'll replace it myself. My M3 is an early production rifle with the setscrews and sealer in the 2 front trigger guard screws to "fix" the accidentally too deep drilled holes. It isn't leaking now, but again, I don't want it to decide to leak one day when I really need it.

Let us know how it works when you get it back.

I have the same issue on my less than one week old M3. 1st regulator creeps to bottle pressure overnight and after a refill. FX sent me an adjustment screw oring and it solved the creep for two day than the problem came back. The bottle adapter vent hole was also leaking 40bars per night. I bought mine through Ken Hicks as well so I’m wonder if that batch of M3 are having same 1st reg issue. The rifle is brand new so I decide to send my M3 to FX instead of waiting for an oring reseal kit. 

Ken did do some tuning but it takes time for the creep to happen. I’m not putting any blame SPAW and Ken did connect my issue with FX right away. This M3 is the 6th Impact I’ve owned from Gen 1 - M3. All my other Impacts worked flawless so I’m thinking this M3 might be a bad batch. 

My m3 30 cal is doing the same. 1st reg set at 160. When I fill it may go to 200 to 180 or who knows where. A shot or 2 and it drop to 150 then surge to 170 or 180 then slowly settle to 150 or 160 . let it sit over night and its at 200 

in other words all over the place 

Please post how long it takes to get your gun back from FX. They had mine for 9 months so I hope, for your sake, their turnaround has improved.

What in the world!!!! What happened? Why did you send it back for service? By the time you got it back the new model was coming out. Sorry to hear it took 9 months; please tell me your rifle is perfect now.

Mine was about 6 months old and still under warranty. The trigger would go off all by itself with safety on and no one touching the gun. Scared the crap out of me the first time it happened because my hunting partner was nearly shot! Local dealer had to send it back TWICE because it came back the first time (after 6 months at FX) still not working. Took 3 more months to get it back the second time. I am in the US and it was returned to the US service center so it’s not like it was sent back to the EU. I hope your experience is more positive and FX has addressed some serious customer service flaws.
