The interesting discussion on my “Doubled My Prophets” thread regarding RTI barrels prompted me to do some research…
…I’m creating this dedicated thread for folks searching for info on this topic in the future.
To start this discussion, we need to define two RTI terms: “LR” (Long Range) and “RPB” (RTI Proprietary Barrel)
Long Range: RTI custom specification Lothar Walther barrels that have a 1:32 twist rate. These barrels are stamped “LR” on the barrel.
RPB: RTI custom specification barrels
The key thing to note here is that not all RPB barrels are “Long Range”, slow 1:32 twist rate barrels.
In this video, RTI’s Robert describes RTI proprietary barrels as “manufactured by Lothar Walther and then subcontracted out to RTI machining”.
Robert goes on to say that the .22 LR barrels will be made in both 24” length (for the Prophet) and 20” length (for the Priest).
I reached out to RTI regarding the twist rate on the .25 Long Range barrel - as I recently acquired one. RTI responded as follows:
So, according to RTI, both the .22 and the .25 Long Range barrels are 1:32 twist rate.
Note that RTI also provided the twist rate for their new Prophet II barrels. Note that these are called RPB (because they are specially made for RTI) but that they are not Long Range (because they don’t have the 1:32 twist)
The RTI Shop in Spain still has some .25 Long Range 24” barrels available (.22s are gone - forever likely). Note that they are now very expensive - almost $600:
You can see on the RTI Shop site that RPB barrels are not all Long Range - this is the new Prophet II 20” barrels in .22 and .25:
Here is some info on the color of the barrels confusion…
At least with their current barrels Lothar Walther barrels the .177 .22 and .25 are silver. The .30 can be black or silver, depending on the length.
The CZ barrels appear to be black.
This also shows that RPB barrels are not also LR (blue square). It shows the $600 Long Range .25 barrels that are still available (red square).
Finally it shows the colors of the .30 Lothar Walther (black or silver depends on length) and CZ barrels.
Going way back to November 2020, it seems that the .177 and .25 Prophet barrels were made by CZ. This chart is from Hard Air Magazine’s 11-2-2020 review of the RTI Prophet:
Summary:
LR stamped on the barrel means it has a 1:32 twist rate.
RTI Proprietary Barrels (RPB) have only been made in .22 and .25 calibers to date.
RTI used both CZ and Lothar Walther barrels in the .177 and .25 calibers in the Prophet over the years.
It appears (to me) that the .22 and .30 Prophet barrels have always been Lothar Walther.
If you have more info on RTI barrels, especially about Prophet barrels, please add it to this thread.

, I have several sizes (weights)made from hinge pins, they are an ideal McGuyver solution!
