G.A.W. AOE Piston Head Spacer (POM)

The G.A.W. AOE Spacer is a precision tuning component from Gungineer Airsoft Works in Japan, designed to facilitate a perfect Angle of Engagement (AOE) between the sector gear and the piston. By installing this spacer between the piston head and the piston body, the piston is shifted rearward by a specific increment, ensuring the sector gear's first tooth picks up the piston at a flatter, more efficient angle. This reduces stress on the initial pickup tooth and significantly lowers the risk of catastrophic failure in high-speed or high-torque builds. Unlike heavy metal washers, these are made of POM (Polyoxymethylene), maintaining a low reciprocating mass while providing high impact resistance. Technical Specifications: Material Construction: Manufactured from high-grade POM (Polyoxymethylene) for its low-friction properties and high compressive strength. Weight Efficiency: Each spacer is ultra-lightweight, ensuring that the piston weight remains low to preserve cyclic speed and reduce gearbox shell impact. Precision Thickness: Manufactured to a consistent thickness (typically 3mm) to allow for predictable and repeatable AOE adjustments. Installation Position: Designed to be sandwiched between the piston head and the piston body for a secure, centered fit. System Longevity: Extends the life of the piston rack and sector gear by distributing the initial pickup force more evenly across the tooth surface. Universal Compatibility: Fits most standard Tokyo Marui-spec AEG piston heads and pistons. Northmark Vault Recommendation: When using AOE spacers, ensure the pickup tooth on the piston is removed or modified to prevent interference with the sector gear as it rotates.
