FX macerick with low speed dots

[RodrigoR]

Hi, I adjusted my Maverick .25 700mm to 38g slug. Second regulator at 121 bar. It features low speed points, even with a different sound when shooting, dropping up to 40fps. Could anyone tell me what it could be? I even bought a new humaair regulator to try to solve it but I haven't installed.

It could be an o ring in the valve. I wish I remembered exactly what they told me. I called FX USA and got immediately on the phone with a tech. Mine was more drastic.

Check your breech o-ring, it may be damaged.

Crank your reg up to 135-140 and then adjust your hammer spring and power wheel until it gets consistent. The gun will actually calm down and get quieter when you use more reg pressure. Right now your hammer is opening your valve more than once. It is bouncing back and forth like a ping pong ball.
