Mec Primer Tray Spring -

The MEC Primer Tray Spring (SKU 285P) is a critical replacement component for reloaders using MEC's high-capacity primer systems. This spring mechanism restores proper function to primer trays designed for bulk ammunition production, where consistent primer feed is essential to workflow efficiency and safety. The primer tray spring brings the pick arm back to its elevated position after each primer drop, ensuring the next round primer seats correctly in the tray carousel—a function that directly impacts reload quality and production speed.

This spring component operates within MEC's 100-capacity primer tray system, engineered to handle high-volume reloading operations. The spring's design allows the pick arm to reset automatically after each primer placement, maintaining the precise timing and indexing required for reliable primer feed. Over time, primer tray springs may fatigue or lose tension due to repeated cycling and the wear inherent in high-production reloading environments. Replacement with an OEM MEC Primer Tray Spring ensures the mechanism returns to factory specifications, restoring the original responsiveness and durability of the system.

Reloaders operating MEC primer trays 285A3 and 385A3 will find this spring essential for maintenance and restoration. Installation is straightforward for users familiar with basic reloader maintenance, requiring only standard hand tools and a few minutes of downtime. This replacement part is ideal for anyone experiencing sluggish primer feed, incomplete arm reset, or inconsistent primer seating—all telltale signs of spring fatigue. Keeping a spare MEC Primer Tray Spring on hand minimizes unexpected delays during critical reloading sessions and ensures uninterrupted production for serious ammunition manufacturers.
