Engineered under LayLax's specialized Proto Gear Arts division, this replacement tappet plate reinforces the high-cycle feeding mechanism inside Tokyo Marui Evolt M4A1 and FPR MK 4 (RS Model) gearboxes. Standard OEM plates frequently suffer from fatigue, rail flex, and fin wear when subjected to intense firing schedules or elevated spring tension. Cast from a low-friction, fatigue-resistant synthetic resin, this upgraded component maintains strict dimensional rigidity and precise nozzle dwell times under sustained load.
Its optimized cam fin geometry guarantees smooth pickup and release off the sector gear, preventing misfeeds and mid-cycle jams during rapid bursts. Additionally, low-resistance guide channels minimize mechanical drag along the gearbox shell, helping conserve battery power while preserving crisp cycle speed. Finished in matte black and engineered for a seamless drop-in fit, this tappet plate provides the structural resilience needed to keep high-performance AEGs feeding flawlessly.
