G.A.W. POM Spring Spacers for AEG Spring Guides (15mm ID)

The G.A.W. Spring Spacers, imported from Gungineer Airsoft Works in Japan, are precision tuning components designed to increase muzzle velocity without the need for a full spring replacement. Manufactured from high-grade POM (Polyoxymethylene), these spacers are exceptionally durable and provide a low-friction surface for the mainspring. While they can be used inside a piston, they are a perfect fit for Retro Arms spring guides, seating securely at the base to increase initial spring tension. Northmark Vault recommends a maximum stack of three spacers; if further power increases are required, it is best practice to move up to a higher spring rating to prevent spring fatigue or mechanical interference. Technical Specifications: Material Construction: High-durability, lightweight POM polymer designed to withstand the constant pressure of high-power springs. Uniform Thickness: Each spacer is manufactured to a consistent thickness, allowing for predictable and granular FPS increases. Spring Guide Compatibility: Specifically engineered to provide a seamless fit on Retro Arms spring guides and other guides with a 10.5mm or smaller shaft. Piston Compatibility: Fits pistons with an internal diameter (ID) of 15mm or greater. Stacking Limit: Recommended maximum of 3 spacers per build to maintain system health and prevent coil bind. Performance Impact: Provides a reliable way to "bump" muzzle velocity to reach maximum field limits with your existing spring. Weight: Minimal mass ensures no significant impact on the reciprocating weight of the piston when used as an internal spacer.
