Parashooter,
I just remembered your paper clip thing and was going to try to find the link.
You did it for me, thanks.

Looking at your picture, I think it was the "A" are I left the most additional material, with the idea of eliminating all but a tiny bit of the second stage.
One thing to be careful of with Parashooter's modification there is such a thing as too much of a good thing. Too much will lower the engagement with the cocking piece and could lead to accidental discharge if the bolt is lifted. Just like ice cream too much of a good thing can harm you.
