DUB-4, Dovetail Utility Base 4 The DUB-4 Dovetail Utility Base 4, is an alternative dovetail clamp mechanism for the top stage for the ARTEMIS 2. The ARTEMIS 2 Top Stage uses the SAM plates by default.
However, if the ARTEMIS owner or operator prefers to continue using the old and slightly wider dovetail plates, he or she can convert the top stage of the ARTEMIS 2 to the old system using the DUB-4 Dovetail Utility Base 4.
