I remember during the summer I was about to go have a war with my pump plugged BBBB and right before I left I tried a test shot and the trigger just snapped so I had to open up the BBBB, take out the broken trigger, open up my leaking tanked big blast, take that good trigger out and put it in my good BBBB.This was such a hassle. Since then I have never plugged a pump on a big blast.

Nice JSB, I really like the "health video" feel. So I'm gussing the OP valve works on the BBBB by that spring being pushed back when the pressure is enough to compress the spring. Then it closes again when the pressure is weak enough to not be able to keep the spring compressed. Hmm, so maybe by replacing that spring, one could essentially allow the gun to work at higher pressures, but still leak air when it is pumped enough to blow the tank. The real trouble would be doing the math to find out exactly how strong a spring you would need in order for it to leak air at a specific PSI.

Very cool. Perhaps one could simply cut off the end of the pump, tighten the screw, and glue it back precisely. I'm pretty sure the Mega Missile has an identical OPRV.

The Mega Missile does in fact have an identical OPRV right down to the screw, tightening it all the way brings the relief pressure up to around 26 pumps, 8 more than at the stock setting.

Edit: If you are keeping the stock trigger setup, the excessive flexing of the trigger will bend the firing pin out of shape and possibly crack the rear of the chamber.

Edit2: Now with pics!

The screw of awesome. Turn clockwise for MAX POWA!

Bent pin and crack in rear of tank, caused by the flexing of the trigger.

Maybe someone can to make a bbbb operate with a trigger based on the spy gear gun's trigger? I don't know, but JSB -if I were you, I would try. Oh, and it HAS to fit inside the bbbb shell. C'mon, I double dog dare ya.

Aimless:

How far did you tighten the screw?

Also:
-Did you tighten it all the way down?
-How much is "all the way"? That is, does it take a few turns to tighten it as much as possible, or less than a full turn?

I don't remember the exact amount of turns, 2-3 maybe, but I tightened it as far as it will go without forcing it, it actually doesn't take much force to turn the screw.
