Hey guys! I'm having some issues with my bt 4 after installing a zerokick hammer, I cock the hammer and shoot and it shoots like 3 shots and decocks. I have replaced the hammer springs from stock to red, yellow and purple . I'm almost at my wit's end; but that's why I joined this forum to get help and give help if I can, thanks in advance.

P.s I have polished the internals, replaced the power tube, modified the air passages on the air valve. I have done this before the zero kick hammer upgrade and it shot great with stock valve.

Well! I just installed my stock hammer and my bt shoots great, it sucks that there was no help but that's life.
Hey die.another.day sorry that there was no info or help. I guess just go back to your stock hammer and spring. It should shoot just fine after that.

I have bad recock issues with a stock spring, any ideas?

Try changing the o-ring on the hammer to see if that helps.. Also make sure that everything on the inside is cleaned and lubed. If nothing else we can send any parts that may be needed.
