I'm fairly new to owning the MP5 platform and its variants. I had a question about removing/replacing the trigger pack in the grip housing. I know you depress the take down lever and rotate the selector switch around until you can remove it. My question is when putting it back in is there any special trick? I have done it but it seems the selector switch is not as smooth to throw as I would have thought, is there a wrong way to put these back together or are all mp5 selectors somewhat stiff to throw? Thanks

Btw these are both Ambi housings

When putting the selector back in, you have to squeeze the left and right levers (in towards each other) BEFORE rotating it back into position.

Works like a charm
