shs cut-off lever compability with d-boys sector gear

[abugroza]

hi,
i found a problem, i saved a spare cut off lever v2 from SHS and when i put it, it seem doesn't engage the sector nub as my unit will go full auto

when i look closer, the lump contact to sector nub is too small compared to military action cut-off lever (if you ever heard one, because i haven't read any forum talking about this brand)

so, could i be bought fake one, or compability of this part is off for d boys GB shell or maybe i should change the gears to SHS if i got the money?

i attach the photos of two for comparison
the black one is SHS and the bright one is military action, and the MA is seems ground up

I would put money on the DBoys gearbox and gears being offspec, not the SHS lever.
