My son's CYMA CM041 all-metal MP5 has a broken mag release lever and mag retention assy. (that's what I'm calling it anyway)
I bought replacement parts (twice!) which unfortunately don't fit.
The front receiver assy is metal and welded together so it's not possible to fit the new button as it's wider than the gap. The original button separates from the assembly to be fitted.
The replacement lever is a also a different style and about 0.5 mm narrower with different cams.
I'm also looking for a cocking lever but that's not critical.
Any help gratefully received as we both enjoy using this wee beasitie.
Cheers.
