The back part on both of the pistons can be screwed off. Take metal back part of the orange piston, and put it on the red one. That way the zero trigger will have maximum grip on the piston. This is not a necessity, but extremely recommended.
Ive used a PDI piston with the Laylax zerotrigger. It works, but doesnt do good for the internals of your gun.
