The Modify Polycarbonate Piston Head is a high performance upgrade part that will increase your airsoft gun's overall performance and reliablity. Made with high strength polycarbonate marterial, the piston head is very light weight without sacrificing durablity. 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.
Features:
- High strength polycarbonate construction
- Decreases wear and tear on internal parts
- Thrust bearings reduces spring tension by letting it spin
- Ported piston head allows o-ring to expand for maximum air compression
