Remember, the hammer spring tension needs to be strong enough to open the poppet valve. The higher the reg setting the more tension is needed. It's a balance.

hi thank you for getting back to me, and yes it came with a factory regulator new, the only problem is we asked huma-air to set it for me at 12 lb which they never, we still don't know if it need's to be sorted out before it goes into the air cylinder, because you're meant to screw it at the top then underneath
thank you

no what happened is I got into the hobby after having an illness I went to the local gun club, after being there a while I asked if I could buy the artemis p15 from him, we've recently found out the spring had been swapped to an even smaller one, i had to give him the rifle at that point because I didn't know how to change the o ring's for it, long story short the rifle was given to him to replace the o ring's all of them had to be done apparentlyhi thank you for getting back to me, and yes it came with a factory regulator new, the only problem is we asked huma-air to set it for me at 12 lb which they never, we still don't know if it need's to be sorted out before it goes into the air cylinder, because you're meant to screw it at the top then underneath
when he had the rifle he said that he had put the rifle to 11.28 energy foot-lbs but we only recently found out that there are o ring's missing screws too short or not there, basically the rifle seems to of been thrown together 
wxxxxxs!! we noticed the spring is so small it's not even the correct size for any of the spring's for the artemis p15, 
I swear talk about having you're pants pulled down or what, but there's you're answer buddy... no. I'm currently looking for a spring and everywhere seems to be sold out lol thank's anyway Upvote 0
