Lee Precision BP2889A Small Primer Arm Assembly Features The Lee BP2889A Small Primer Arm Assembly replaces the small primer seating arm on several Lee press models including the Breech Lock Challenger Press the Classic Cast Press and the Classic Turret Press. It also fits 4-hole turret presses and value turret press kits manufactured before 2018 that use a red base casting giving owners of older Lee presses a path to keep priming systems functional. This arm handles small primer pockets specifically so reloaders working with small rifle or small pistol primers can restore full priming capability after wear or damage. Replacing a worn arm assembly is far more economical than replacing the press entirely. Because this part is press specific reloaders should confirm which Lee press model they own before ordering to ensure correct fitment with the red base casting style frame. Keeping priming components on hand allows reloaders to perform quick repairs without downtime between loading sessions. Lee Precision designs its presses with serviceable parts like this arm assembly to extend the usable life of equipment already in a reloader s shop. This small primer arm assembly is available for sale at GrabAGun for Lee press owners needing a direct replacement part.
