Title: Valve help
Post by: PushingPELLETS on December 04, 2015, 10:59:32 PM

I'm looking into a a few options need a little guidance Herr which is a qb78 valve I was wondering if anyone could tell me either a) good options for modifying the factory unit and benefits( stuff I can do on my own)  b) you know who sells a tuned xp qb78 valve...worth the money over a factory unit with little work....or does it not improve to much thanks...it would be used in a xs60pcp  .22 thanks

I've been shooting nothing but Springers...first venture into the realm of hpa

I think your best bet would be to mod a stock valve yourself.  It is pretty easy and can be done with basic hand tools.  Just google "Qb78 valve mods" and you can check out this tuning guide.
