12 bucks for a crappy one. spend about $20 on a good one its well worth it! i may have one of the crappy WGPs laying around i will have to check monday.
I don't really care if it's good or not, I just haven't played in probably 8 months and I want to figure out this velocity problem with my gun. My reg is fine (and I've tried others) and I've tried stiffer main springs, so I'm thinking something is up with my valve and I just need something to get at it and get a new one if needed.
