Let me ask you a question Fisher, when you pull back the priming handle, do you hear the catch click ? In other words, is this a mechanical issue with the catch, or is it just simply not catching at all ?

The reason I ask is that on certain blasters, adding an additional spring reduces the amount of travel of the plunger rod, and physically prevents the plunger from sliding all the way back to engage the catch. I can't remember if the Mav is one of them.

See, adding another spring of exactly the same diameter means the coils stack up on top of each other. So it effectively doubles the compressed length of the spring. If that's more than the travel of the plunger rod, then it can't reach the catch mech.

I had a similar problem with another pistol - can't remember which one - and had to resort to getting a stronger spring.
