MP5 mag fix 2
Once you locate where the leakage coming from, release all the gas before disassembly.
be very carefully not to damage the gas release valve when pushing out the inner mag tank.
first push out pin
then push in gas release valve, using screwdriver to push out the inner gas mag from the top. you may have to force to push a bit,
BE CAREFUL NOT TO DAMAGE THE GAS RELEASE VALVE when the inner mag tank is being pushedg down through the mag housing
when the inner mag tank half the way out, tape the middle of the mag in case part#43 inner mag tank support for the bb loading spring falling out.
now you have the inner mag tank out already.
*if you damage the gas release valve when movign the inner mag tank out, you may possible bend the inside gas release pin. that could cause the pin stuck in or firing problem. simply remove the smallest o-ring and push tight to open the valve, gently bend the other end and make it back in straight would work fine. it happened on me twice, lol...
