Well, I just got my return shipping lable from Pyramid. The gun came the other day with 0 psi. And leaked just like every other one. I guess it was worth a try but after seeing how the gun was made, I knew it would be a waste of time to try to fix it, besides I wouldn't be able to return it if I messed with it. It's a shame that Crossman/Benjamin would put their name on such a POS.
Maybe new old stock from the original run and o-rings drying out.
