It sounds like CSMC is still building RBLs. That does not seem entirely consistent with what they are saying on their website:
1. What is the RBL Reserve?: The RBL Reserve is the last of the RBL's before the A-10 American begins full production. Connecticut Shotgun Mfg. Co. wanted to be sure that outdoor enthusiasts had at least one last chance to own a new RBL. Don't delay, no more RBL's are planned for production.
While I support CSMC's efforts to produce quality double-barrel guns in the US, some of their marketing statements seem misleading to me. The A10 has been in production for several years, which would indicate that there should be no new RBL Reserves being made or offered for sale. Clearly, that is not the case, however - they are still releasing new RBL Reserves on their website and apparently are still building them to order.
CSMC makes nice guns, too bad they can't be a little more straight-forward with their marketing.
