You should be able to get little check valves at pet stores in the aquarium section they only cost a few dollars and should be small enough to fit in the at3k shell and they don't have much internal volume so "dead space" isn't really to much of a problem.
$79 is much better. What was the shipping like for your order i know you had extra stuff but just curious. Thirdly 250psi is more then enough. I assume its 0-250psi? and how accurate/consistent is the regulator?
Hm. $140 for just a regulator seems a bit steep to me, because I would still have to buy an HPA tank which appear to be around 80+ dollars. I was hoping to get this set up bit for under 200. BUT i guess if this set up works I may have to look into it.
I know this topic is a little old and I don't really have anything new to add but I was mainly wondering if CS forgot to post the pictures of his old set up here. Secondly i was also wondering if Doom made any head way on his regulator troubles. I am looking to start gathering the parts for this set up and i could use a little feedback.
