Purchased Vulcan 3 and Uragan 2 .30 700mm a few months apart, about a year back. With similar power, shooting side-by-side, prefer U2. Balanced valve technology makes less ammo fussy, smoother action and quieter operation. WM

I was told by someone who knows these inside out that V3 valve holds up a lot better when it comes to serious power levels. The balanced valve is supposed to be the weak point in U2 tuning.
Something to think about. There's something for everyone 👍

This is going to be a long stretch. But Is there any way you could take a picture of how the valve assembly goes together with the dwell pin, sleeve, spring and pin probe. I took mine apart and can't get the gun to not leak out of the barrel. I think I may have something wrong with something I the valve.

Even drawing a picture would help.

Sorry bud, I am unable to right now and can’t think of how he went off the top of my head.

@rtiarms are you able to help out with this?

With the barrels we noticed just last week that few of them in 9mm, were not machined as per our specs by Lothar Walther (they make and turn our barrels except the chamber - we do that part ourselves). That could cause the problem since the monocore could get misaligned.

i have the mora and am having this exact issue mine was bad enough that the slug didn't fire but because i couldn't get a consistent impact i didn't know and tried to load another causing a jamb breaking the cocking arm I've had to 3d print my own cause no one responded to me and i couldn't find the part to buy on my own

I can’t say for sure on mine since I can no longer shoot it, but I’m wondering if it was the tensioning nut behind the shroud base. There looks to be a gromet inside of it that when you tighten the nut down, it applies tension, holding it to the front of the rail. I would guess with mine being loose it allows the barrel to wiggle all the way back to the chamber like FX guns would

the 3 Alen screws on the top of the but stock in front of the magazine hold in the barrel for the barrel to move they would have to be loose the barrel itself holds the shroud on otherwise the barrel free floats unless u have the shims in where the barrel passes through the black nut that's between the shroud and the stock

I recently received an RTI Mora .357 sniper that I had ordered. First impressions, it’s a beautiful gun, feels great in the hands, very light and smooth cocking and great trigger, also very quiet. Out of the box from Talon Tunes it was shooting 100gr zan slugs at around 215 fpe.

Issues I am having: pellets and slugs are clipping inside of the air stripper in the shroud, throwing accuracy way off. I have tried 3 different weighted Zan slugs, 2 different weights of NSA slugs, some home cast slugs and JSB pellets. I opened up the air stripper a little which helped accuracy without the provided hush 50 silencer attached, but now clips with the silencer attached. I’ve spent some time shooting without the silencer. When I go to air up the gun and then return to shooting, the point of impact changes and I have to zero it again, this happens everytime. During one of my shooting sessions, the shroud base that clamps to the barrel blew back and I got blasted with air. Now the trigger is slowly moving further and further back into the handle. Currently have about 400 rounds shot through it. The gun did not come with the cheek rest or a user manual which I have read others complain about as well. Not exactly what I expected from a gun in this price range, but they are a new release and I guess there will be bugs to work out. Currently working with Talon Tunes to see what we do from here.

Just wanted to share my findings and see what others might be experiencing.
