Lyman Priming Arm Universal

The Lyman Priming Arm Universal is a replacement priming component designed for reloaders using Lyman's Crusher and Crusher 2 press systems. This versatile arm accommodates both the T-Mag and T-Mag 2 press models, making it an essential backup part for shooters who maintain multiple reload stations or need a spare when their primary arm wears from frequent use.

Constructed from aluminum and steel, the arm combines lightweight durability with the structural rigidity required for consistent primer seating. The spring-loaded design retracts the arm away from the ram slot during the press stroke, then positions it automatically for the next primer feed cycle—eliminating manual positioning and reducing operator fatigue during long reloading sessions. The universal priming arm includes two interchangeable priming sleeves: one sized for small primers (such as .22 Hornet or small rifle) and another for large primers (.308 Winchester, .30-06, and comparable magnum rifle cartridges). This dual-sleeve configuration allows a single arm to handle the full spectrum of primer sizes without purchasing separate assemblies.

Reloaders managing high-volume production runs, those transitioning between different cartridge families, or anyone operating multiple press stations benefit from keeping a spare universal priming arm on hand. The lightweight 0.13 lb design makes storage convenient, and the compact footprint (3.25 x 0.65 x 3.6 inches) fits standard tool drawers. Installation is straightforward on compatible Lyman press models, requiring only basic familiarity with press assembly and disassembly.
