The SHS POM Poly carbonate Piston Head is a high performance upgrade part that will increase your airsoft gun's overall performance and reliability. Made with high strength poly carbonate material, the piston head is very light weight without sacrificing durability. The piston head features thrust bearings that allow the AEG's spring to spin freely. This reduces mechanical stress inside the gearbox and increases the life span of your internal parts.
- High strength poly carbonate and aluminum construction
- Thrust bearings reduces spring tension by letting it spin
- Decreases wear and tear on internal parts
- Ported piston head allows o-ring to expand for maximum air compression
