Mutation Whisper AEG Piston Head – High-Seal Silent Compression Upgrade for Ver.2/Ver.3 Gearboxes

A lightweight, high-seal piston head designed to improve compression consistency, reduce vibration, and create a quieter shot cycle in upgraded AEG builds.

The Mutation Whisper AEG Piston Head is engineered to deliver improved air seal, reduced mechanical noise, and reliable compression in both stock and upgraded AEG gearboxes. Its lightweight polymer construction minimizes piston mass, enhancing trigger response and reducing overall vibration within the gearbox.

Ideal for performance-oriented builds such as DMR platforms, brushless motor setups, and precision hop-up tuned rifles, this piston head provides consistent FPS and smooth cycling without adding unnecessary weight.

Features:

• High-efficiency O-ring design for strong and consistent air seal
• Lightweight polymer construction reduces reciprocating mass and vibration
• Improves shot-to-shot FPS stability in upgraded rifles
• Helps reduce gearbox resonance for a quieter acoustic profile
• Compatible with most Version 2 and Version 3 AEG pistons
• Suitable for high-FPS builds, brushless systems, and precision hop-up configurations

Compatibility:

• Fits standard Ver.2 and Ver.3 AEG gearboxes
• Works with reinforced polymer and CNC piston bodies
• Supports springs in the moderate to high-tension range

Included:

• Mutation Whisper AEG Piston Head with pre-installed O-ring
