The JR site shows a video that explains how modular the design is.
Bolt head, barrel, and mag well can be swapped out.
Can the Thureon do the same? The TD site doesnt give a lot of detail. It does list the calibres available.
9mm NATO
.45 ACP
.40 S&W
10mm
.357 SIG
You can't swap calibers on the Thureon.
