Lee Precision primer arm assembly large BP2889B

Lee Precision large primer arm assembly BP2889B

The large primer arm assembly is the complete priming arm for large size primers for Lee Precision single-stage and turret presses. It is the unit that carries the primer cup under the case during the priming stroke: it should be replaced when the cup is worn, when the arm has excessive play, or when switching permanently to the other primer size.

Lee supplies it as a ready-to-mount assembly, with spare part code BP2889B and sales code 91963. One is required per press. Be careful not to confuse it with the BP1169A arm, designed exclusively for the Breech Lock Classic Cast: the two units are not interchangeable, and the identification criterion indicated by Lee is the square hole on the side of the BP1169A.
