FPS CNC POM Double O-Ring AEG Piston Head with Ball Bearings & Adjustable AOE (TPPA)

Lightweight CNC POM piston head with dual O-rings, thrust bearings, and an adjustable AOE system for improved airseal, durability, and gearbox tuning precision.

The FPS CNC POM Double O-Ring Piston Head (TPPA) is engineered for AEG builders seeking maximum airseal efficiency, smooth compression, and precise AOE control. Constructed from CNC-machined POM polymer, this piston head delivers low friction, high durability, and reduced reciprocating mass, making it ideal for high-performance setups.

Dual O-rings ensure superior airseal consistency between shots, while the integrated ball bearing stack helps maintain spring alignment and reduces torsional stress during compression. The adjustable AOE insert allows fine tuning of piston engagement to improve gearbox longevity and optimize impact surfaces.

This piston head is well-suited for upgraded AEGs, DMR builds, high-FPS configurations, and setups requiring stable, reliable air volume.
