EPES Piston Head AOE Spacer Pad 0.5mm – 3 Pack

Precise angle of engagement is critical to any reliable AEG build. The EPES Piston Head AOE Spacer Pad 0.5mm (3 pack) addresses a common gearbox problem: misalignment between the sector gear tooth and piston tooth, which causes sluggish trigger response, piston noise, and premature wear.

Key Features

• Duralumin construction – Lightweight, rigid, and corrosion-resistant for consistent performance
• 0.5mm thickness – Precise AOE correction without excessive shimming
• Three-pack format – Multiple spacers for different gearbox tweaks and spares
• Easy installation – Simply place between piston head and gearbox cover
• Cost-effective upgrade – Improves trigger response and gearbox longevity

Real-World Use Cases

AOE correction is essential for milsim and skirmish players running upgraded springs and high-speed builds. Misaligned engagement causes the piston to strike the sector gear tooth at an angle, creating noise, slowing trigger response, and wearing the piston prematurely. These spacer pads shift the piston head position by exactly 0.5mm, allowing you to dial in perfect alignment for your specific gearbox and spring configuration.
