IM,

On my RBL-12 muzzles I can't tell where the barrels end and the solder and ribs start. I also have an RBL-20 which I can see a very fine difference between the barrels and bibs.

If your RBL-12 has anything other than barrel and ribs showing at the muzzle there may be a defect. Better call CSMC!
