Tappet plate spring kit designed for AR15 and AK platforms using standard V2 and V3 gearboxes. This set allows precise tuning of tappet plate tension, a critical factor in BB feeding reliability and correct synchronization between nozzle and sector gear.

RetroArms engineering focuses on functional precision components: this spring set enables adjustment of feeding behavior depending on build configuration, from standard setups to high-speed or high-stress tuning platforms.

The three stiffness levels directly influence tappet return speed, affecting feeding consistency, nozzle timing, and overall cycle stability. A small but essential component for eliminating misfeeds, double feeds, and timing inconsistencies.
