Yes. Accuracy isn't that great. Have a green mountain barrel and a huma reg that I'm going to install. Goinuuuuug to have to send out the action and barrel to someone to replace the stock barrel. You have the stock barrel and reg?

miksatx · « **Reply #6 on:** February 15, 2018, 10:45:28 PM »

i've got the green mountian barrel an huma already fitted.

I knew that

and don't forget the Weihrauch moderator that you added also

kzz1kaw · « **Reply #8 on:** February 16, 2018, 02:28:05 AM »

How is the accuracy out to 50? What is the reg set to? From what I see on the shot string 40 shots. Have you tried tuning for say 850 fps?

miksatx · « **Reply #9 on:** February 16, 2018, 08:25:00 AM »

Hi Jack thanks for reminding me lol.
Hi Ken 855 is top end on this gun, reg is set at 130b. I don't have the room to shoot 50yards. But I'd say it on par with a marauder shooting @ 50. I sent it off for a buddy to hunt with. He said these Bunnies were taken from 10 to 75 yards, .

badgerfarm · « **Reply #10 on:** February 16, 2018, 10:30:22 AM »

Who is a good supplier for the Huma reg for the P15? I'm going to fit one to mine and do a little tuning. I've heard that the factory regs weren't up to par and my stock barrel is quite accurate out to fifty yards with 25 gr JSBs . Just in case where could a guy turn up a GM barrel in the event that I wanted to stretch it out to 100 yds? I've got a lathe and can do the mods with no problem.

Did you have a shot string with stats from when your P15 was stock ?

All my info and experience with this p15 posted AirMax P15 .25 over at TalonTunes, other bullpups section.

Tweeter · « **Reply #14 on:** February 16, 2018, 08:06:20 PM »

Hey Badger, Trenier has the huma reg for the p12, would check but this may fit the p15 if they use the same airtube?

Order direct from Huma, they will ship...https://www.huma-air.com/Artemis-P15-tuning-pressure-regulator

stony30 · « **Reply #18 on:** February 17, 2018, 02:10:53 PM »

Thanks. Does the P15 reg definitely need to be replaced ? I'll try to get a chrony and do a shot string starting at 200 to 220 bar.

miksatx · « **Reply #19 on:** February 17, 2018, 02:31:47 PM »

stony30, chrony a definite need to determine how the regulator is working.
