I think I'll try M102404 method. But I always wonder, after grinding threads, won't it be difficult to put the nozzle back on the "new" thread? I'll also try Co2 and see what breaks. But I'm still wondering why there is no gains in fps with Co2, can someone explain this? Let say that propane has a 120psi, a Co2 200psi (no point of saying somewhere between 200 to 800pis because I ain't see an airsoft yet runing a 800psi) with 80psi more, you should have an incredible gain in fsp!?
And what about the claim of 600fps from TSC?
So many questions
