'The standard' is to turn your hop fully off then just go from the front. Long as you're not using anything abrasive and are careful/gentle/don't go ham fisted at it then it'll be absolutely fine, nothing adverse is going to happen.
FINALLY got my hands on an MP5 and four spare mags. Found a solution for mounting a scout light which works really well, and allows use of the original TM forend for maximum battery space. The claw mount is the wide TM version. You can mount an optic towards the back, with room to spare for a Surefire offset mount in front of it.
The Scout light is long enough that shadowing isn’t an issue, but short enough that ambidextrous handling is still possible without having to change the forend and use a vertical grip. Pressure switch is just taped neatly on the top, as I like to shoot thumb over bore / C-clamp.
Got a night game coming up soon and can’t wait to try her out. The suppressor is the TM pro tracer, attached to the adapter which comes in the box with the MP5. Looks good enough for me.
I’ve just got an Acetech mini tracer unit (Lighter S iirc ) fitted in mine , directly to the -14mm thread that is under that cap you’ve highlighted , then the outer screwed back on . Works perfectly and you don’t even know it’s there till you need it , like just now 😛
