Put the o-ring in hot water is not work, the plastic is heat resistance......

I guess it is the design problem, i found my KJ m9 have a "ladder" shape between the valve,thread, and oring,..............but the hudson is almost a straight line.......

The valve have four o-ring , the m3a1 o-rings fit the 2 of them only(those inside the value) i replace the outer one, still leakage, when i replace the inner one(inside the valve spring), i broken the valve.........................


i give up the modification..........I think whether i buy another magzine, but i think it should have the same problem.,..........


The gun become for display only.............
