MEC Enhanced Tappet Plate Spring: The Solution to Midcap Syndrome

The MEC Enhanced Tappet Plate Spring is the only tappet plate spring officially tested and endorsed by PTS. This spring is engineered to combat the common issue known as "Midcap Syndrome" in Airsoft Electric Guns (AEGs).

Midcap Syndrome occurs when the high upward pressure from a fully loaded midcap magazine pushes the nozzle upwards and out of alignment. This causes drag on the nozzle, preventing it from returning quickly enough to consistently load the next BB, leading to unnatural FPS fluctuations and inconsistent feeding. A weak tappet plate spring is typically the culprit.

Core Advantages: Performance Boost for High-Capacity Mags

• PTS Official Endorsement: This spring has been extensively tested for use with the PTS EPM and EPM1 magazines, confirming its reliability under extreme stress.
• Eliminates Midcap Syndrome: Particularly vital when using the 250-round capacity PTS EPM1, where the immensely long magazine spring causes higher-than-usual upward pressure. The enhanced tension ensures the nozzle snaps back into alignment quickly and reliably.
• Unmatched Durability: Constructed from the toughest steel wire with a heavy load ability, making it a reliable and desirable choice for high-performance builds.
• Wide Compatibility: Suitable for most standard V2 and V3 gearboxes, making it a versatile upgrade for various AEG models.
