ICS MP5A4 selector switch
 

My Selector switch is loose and the only position it locks into solidly is safe, but when semi auto, upon a tap it will end up in full auto...

suggestions?

any help is greatly appreciated, thank you.

Bump?
im sure this is a simple and common problem.....

This problem is common to mp5.
The only way to fix it is replacing lower receiver

This happens because the little pin behind the selector damages the lower receiver. You can see it from the little groove it makes.

ouch.....i guess i can cope with it its not THAT bad....
but just out of curiousity....replacing the lower receiver would cost about....?

Like 25 bucks or so. Its not a restricted item so you can order it yourself. Try redwolf or uncompany.
