Maple Leaf ZERO Resistance Spring Guide for Tokyo Marui VSR-10

"I got this with the ML cylinder upgrade kit (M145) - the other review is correct regarding fitment. It also does not work in the VSR-ONE. The "pin" on the stock spring guide in the VSR-ONE is pretty small so I will have to grind this one down quite a bit to get it to work with the stock trigger set up.

Quality seems good; it is very light weight compared to the stock one in the SSG-10 and a smaller diameter of course (i.e. 9mm springs vs 13mm)

"I'll get to the point, this is made to work with the maple leaf piston and probably the zero trigger. It is very high quality, but unusable to me because it won't fit in my standard size after market piston. It doesn't even fit the backing pin that slides up through the trigger box. For me to use it, i am going to wait for my plastic one to break then grind away the metal until it fits.

Again, 3 stars because it is very high quality and does what it says it will. But, it doesn't fit standard parts.
