Tuning Uragan power adjuster

[vmaxpro]

Some of you have seen my 150 fpe uragan. I wanted to see how pellets would fly at that power just for the hell of it. Well didnt go so well it completely obliterated the pellet in the bore. So, I decided this week Im going to machine the body and make a power adjuster! Its gonna be just like the brococks if your familiar with them. Stay tuned!

Re post back the pics of your rig on your tread here. Some of us are unfamiliar with your uragan!

Heres the start of the final. More coming, working on the knob now. I made the knob removable so I didnt have to slot the stock just a hole.

Body is bored out, lines up perfect. I need to get the knob annodized. Just need to drill and ream the hole for the detent plunger and spring. It acts as the retainer as well but I might put a clip on the end as an extra safety measure.

Heres a new threaded valve/peek poppet. The first one i made was pinned and I didnt like it. The threads are timed and lines up nicely.

Done with tuning! Came out awesome! I dropped the power on it big time. But I love it even more now. Heres the results! Doesnt seem like much? This is with only 95 bar on the reg!

jsb 44.75gr

1005fps

971 fps

890fps

750 fps

558 fps



Best part? Nsa 65.5 slug still goes 880 fps. Yes its 130 fps slower than it was. But the gun is smoother, I can now adjust for lighter slugs and pellets. Effeciency went thru the roof too.
