FX M3 Front Reg Question ( Delete via internals removal)

I bet there's an adapter to delete it or maybe the M4 adapter works (I don't know if it does) If it just keep creeping on you, try a huma up front or let it creep all it wants. I'm super glad I huma converted from the delrin piston amps on my m3.

If there's no atmospheric reference port, technically you could delete the internals. Im a fan of the dual regs, so I never looked around and thought out the delete. I hope this is of some use to you.

I just left the 1st reg wide open, if I remember correctly that was 225 bar.
I believe you're in the ballpark of either the guage or the Bellville stack max for the front reg. I can't remember which. Just beware the 2nd reg behind the trigger that's the one I was having piston face deformation issues with at 165 bar at one point combined with summer heat/sun of about 110f. If you could get the M4 reg or a huma for behind the trigger I think it would be problem free even if you heatsoak your gun like me. The brass piston with a delrin seat seems to be far superior and long lived for my uses.
 
Well.....Removed the internals...Piston assembly and adjuster . Drilled the vent hole out to 2.5mm and tapped it for a 3mm plug screw ( sealed with Loctite 680)
I have a Sabre Tactical Front Reg Delete adapter incoming, but wont arrive for a week or so....so being impatient to try new things i modded the original front reg as above..
Installed the Huma gen 3 High pressure 2ng Reg...... So far Excellent results..
