bb shower question‏

[White Fox]

Hi guys,

I just bought 2 Mad Bull 120 rds M922A1 BB Shower, and I want to know if its normal that my pressure slowly goes down after I filled them. I'm pretty sure I dont have any leaks.
For example, im playing for 45 minutes then fire a grenade, and its does like the half/third of the range compared to when its fresh refilled.
Maybe its because the pressure tank in the grenade need to be more used to adequately store gas ?
Im using propane.

thanks for your help!

Just a guess from me, but I would say you have a teensy tiny leak.

You have a leak. They should keep their pressure. Add a little silicon oil during your next fill and it should solve the problem.

Open them up. Give the orings a good silicone oil bath. Remove fill valve and do the same. Replace and happy hunting.
