The one in the FAR pushes a crank to move the pin, what I am suggesting is switching the rod so that it is attached at the top of the trigger (where the trigger is attached to the gun now) and similarly moving the attaching point to where the rod was, and then doing away with the crank/pin thing. You would then replace the crank with another one, with 2 holes in it, the bottom one being attached to your trigger rod and the top attaching the crank to th gun. The other part of the crank to make an "L" shape (that is really kind of upsidedown and backwords) would stick out into the plunger assembly at an angle. That way, when you pull the trigger it pulls the bottom of the crank which lowers the part sticking into the plunger and the plunger fires. As an added bonus, you don't need to bevel the plunger to get it to depress the trigger crank.
And I know that somwhere, you were also talking about how the spring buckled so you added the spring guide, but now the plunger is too heavy; on my airsoft guns anyway the spring guide is in the back of the gun and the plunger can pass over them. That might up your preformance.
I made a picture/diagram thing, thanks to help from The Infinite Shindig:
