FX FX Impact M3 modified valving system results .22 600mm barrel 18.13 grain jsb

[mubhaur]

I have done some internal modifications in the valve and valve seat of M3. Pics are hereunder

Today after a long time after these mods I tested the gun.

The obtained data is as under

1st regulator 170 bars
2nd regulator 100 bars
Valve full open
Valve spring wire thickness 0.75mm
Barrel 600mm
Dual transfer port
Pin probe
Hammer setting 1.6 on micro scale
Power wheel on 1
Maximum fps 1060 fps

I feel that at 100 bar reg these are improved results.

May I request you friends to share your M3's fps with 18.13 grain jsb at 100 bar reg pressure?

Regards,

What hammer weight?

The hammer weight is original that comes with M3. Have put one stainless steel spacer that may be of one gram
