Re: mp5 problems

the semi can be 2 things , selector plate could be worn or the cutoff is worn

the fizzy noise is not a good lol , but could be just a lose connection , take the bottom of the grip off and remove it to have a better look

Re: mp5 problems

Furthermore, if semi automatic is gone and the Cut-off lever and the selector plate are fine, there's a little protruding notch near the cut off lever inside the V2 box - this notch is part of the GB case.

If it's missing, then that's why SA doesn't work
