FX Impact M3 best regulator fix?

[Scotay42]

I have an M3 that was returned from an ebay buyer that is now not working right at the front reg and is leaking at the power plenum. I plan to do a full reseal, but also replace the regulators or bypass the front reg and use a high pressure rear huma reg. What is the best course of action from guys that jave had this problem?

Are you just fixing it and returning it to the buyer or keeping it? What reg pressure range do you or the buyer plan to run? Is it going to be a nasty slug gun or a versatile all rounder?

You can buy a front reg delete kit. Also the newer brass version of the AMP reg will handle being the only reg in the gun quite well.
The whole two reg thing was IMO more of a sales gimmick than providing much advantage. Notice the M4 is a single reg gun.

Well, the buyer returned statimg the trigger was inop, safety inop and it did not cock. I sent a rifle fully functional and full of air, i was using it every night pesting. It was returned with the bottle removed and empty. The trigger working perfect, safety working and also cocking. When i put the bottle on the first reg jumper to 220bar matching tank preasure, it was previously set to 170bar, and then stating spewing air from the power plenum while reading 90-95 bar on the rear reg, previously set to 80bar. With this happenning i disputed the return with ebay as the trigger doesnt magically fix itself and that my air rifle was tamperred with. Ebay judged in my favor. So now on to the repair, and more of an all arounder. It is currently a comlact .25 but may turn it to a .22 for midweight slugs 20-25g.

PM returned. And do not delete the first reg with a 300cc bottle.

Did you mean to say 300b bottle?

I have the first reg delete, and HP Huma reg on my M3 .22 cal. With the 800mm barrel and 185 on the reg it will push 40gr slugs to 1060 FPS. But, I wasn't impressed with the harmonics and those pressures and speeds. At 155 bar it still pushed 40gr slightly over a grand and is a laser beam. At 155 it's super consistent and happy harmonics all around. Over 175 and it feels very strained.

Nope

What happens when ebay judges in your favor? Do you get reimbursed for needed repairs?

For pellets, i'd keep both regs. AMP w/brass piston or Huma.
For slugs, i'd delete the 1st reg and go Huma extra high pressure.
