Airsoft Mutation The Whisper Mk. II CNC Delrin Piston Head

Threadlock (Blue) is still required

Toss it in any build you want and expect it to last longer than anything in the gearbox.

The Whisper MK.II (Mark 2) is the strongest polymer piston head on the market. 

• CNCed from a block of Dupont Toughened Delrin
  Very low coefficient of friction and extremely high impact resistance

• As durable as an aluminum piston head
  While granting all the benefits of a polymer piston head.

• Specially designed radii
  Prevents piston head from touching cylinder walls and creates a perfect seal around the oring instead of a flat surface.

• High Quality Black Oxide M3 Hex Screw

• CNC Aircraft Grade 7075 Aluminum Threads

• Flat Front Face Edge to Edge to Reduce Dead Air Zone
  Good for setups requiring maximum useable air volume.

• Slight AOE Correction 
  Thicker than average piston heads .
  

• FKM Oring
