-Break in (1,000 shots to break in)
-Some leaks (just use tape and common sense)
My old maxflo on my imp started to leak and no matter what I couldn't fix it. So I went down to Gunfighter's and they only had two kinds of regs. It was either a cp (75$!) or this new warrior (44$). I decided to give it a try and it works pretty well.
When I first tried it there was a slight leak in the adjustment port, but plumber's tape took care of it. Also I love the design! It's small and the line goes into the bottom rather than the side. There are two side ports for gauges.
I played with it over the weekend. At the chrono it was jumping 20-25 fps, not the worst i've seen. However after about 1,000 rnds it was pretty consistent (120psi and +/-7 fps)
