RTI PROPHET COMPACT II 22 caliber CZ barrel stuck

[airgunmike56]

I got the barrel out with vice grips on the RTI tool and a lot of force, Scratch marks on the barrel by the two orings, A few metal shavings also very fine, I am not putting the barrel back in, Just way to tight..
Cleaned everything up and the 177 LW barrel snugged right in, I will see if I can post the pictures up tomorrow.
I will get a word into RTI and see what they have to say about this..

Yikes! Back that phone up so it will focus. Then we can enlarge the clear picture that you took.

That is some serious swarf you got there.

Did the rifle come from the manufacturer like that?

 

[Vetmx]

From what I can see I would check the TP hole and grub screw hole for any burrs. It only takes a couple thousandths between barrels to make one catch on something and one not. I would also take some calipers to both barrels and compare dimensions in a few key areas. That info in itself will give more credibility to the email you plan to send to Rok.

In this blurry pic, is this a lip or is it just wore off. I can’t tell

And what is that in the o-ring groove…gross

Camera focus tip..lay the part you're photographing on the work surface..something not moving. Then move back 3-4 feet and use the camera zoom feature to get closer for the detail you want. At a further distance, the camera will have an easier time doing its focus thing.

Hi Mike,

I have 2 full sized Prophet Performance v1s - a .22 LR and a .25 LR .

I swapped the .177 LW barrel into the .25. The standard RTI PP v1 spring is 2.65”. The hammer weight is 30.65g in both my rifles.

To shoot .177, I picked up an extra spring when I bought the .177 510mm barrel.

I cut the extra spring and flattened the end - it is now 2.46”. I use this shorter spring when I’m shooting .177. This enables me to dial down the velocity a bit with .177 using the hammer spring adjuster screw.

I’m shooting 10.3g JSBs at 885-895 fps with the reg at 85 bar.

This was the best of about 5 groups I shot recently - this was outstanding but all groups were well under a dime at 30 yards. I was dialing it in at 30 yards to use it in the “30 Yard Challenge” on this forum, lol.

Good luck with your new LW RTI .177 - maybe this info will help you get it dialed in.

How did your CZ barrel shoot btw?

I will get some better pictures up, If it was a burr in chamber the LW 177 barrel would not slip in smooth, Thanks for the picture info.
EPG,
The CZ and the LW shoot pretty well lights out, I have the 25 LW, and the 30 also.

What probably happened was the barrel was pushed just a little too far back towards the mag. When the grub screw was tightened it clipped the detent shearing off a tiny shard. With such tight tolerances that shard became a wedge. When you seat your barrel to your mag, have to make sure RTI made the detent big enough so you don’t clip it.

 

[airgunmike56]

I got some better pictures the CZ barrel along side my 30 cal LW barrel, Both LW barrels slip in tight but just real snug, The CZ 22 barrel I would have to use come major force to get back in not something I like to do to any gun...

Hi Mike,

I‘d polish that CZ barrel using sandpaper, polishing paper and elbow grease until it measures the exact same diameter as your LW barrels- it’s likely only a thousandth or two off. Might also want to polish the breech where it slides in.

Are the CZ barrels for the Prophet choked?

 

[Scotty1]

The 20”, .22 and .25 I’ve had were indeed choked.

 

[airgunmike56]

EPG, I would be on the sand paper out but this is a 2000 dollar gun, This is the same company that sent me a 177 Magazine that did not work, I even sent a video in of the magazine as requested ,, They said they would send a new magazine and never did. I will wait until I get an answer from RTI.

OOPs I just got a e mail from RTI , I screwed up and called my Prophet a Priest , So I just explained that I read so mush about the guns I just called it the wrong name...
They did have a record of me just buying the Prophet PP II compact... I really need to proof read what I send , I did send more pictures of the barrel and told them I really do not want to sand it down with sand paper, Just not comfortable doing it. I could send the barrel back to them and let them take a look at it on my I would pay, They would be out nothing.
Mike

 

[airgunmike56]

I just sent my 3ed Email to RTI , I informed them I would pay to ship the barrel back to them to take a look at it, I sent more pictures to show the marks on the barrel, I sure do not want to take sandpaper to the barrel, When I have to start fixing RTI problems it's when I stop buying their products.

[airgunmike56]

Not sure if I should copy and paste there post here, But in a nut shell RTI said they would give me 70 euros and I could keep the barrel,,No The gun is under warranty I want the barrel fixed or I want a new barrel. I do not think this is to much to ask for a 2000 dollar gun. I got hold of AOA and ask if they would honor the RTI Warranty .

If you’re not comfortable with how RTI is handling this, I would talk to someone at AOA. And I mean talk, F emails. They should guide you in a direction. When I bought my first RTI, pretty much before anyone even noticed them, I had an issue. I dealt with a dude named Rich at AOA. He handled things great. When I had an issue with the second gun, the gen 1 adjustable reg, AOA didn’t have a cure so I direct dealt with RTI and they were great. They have grown since then with a ton more guns out there acting up. If their newest model is having some issues hopefully their CS won’t suffer with oddball issues like you experienced.

Vetmx Thanks,
I think I remember you from T A G and your Prest you bought....
over 10 years in PCPs and never delt with any warranty, Well except on my Vulcan 177 I complained about a twang, And AGT sent me a hammer,spring and a weight and some other parts free just sent it to me, They were reading the forms .
I have bought three or four guns from AOA always super good, I will give them a call and see what they say,,
