Copyright © Airsoft Mutation Inc. All rights reserved.

Threadlock (Blue) is still required

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

The Whisper is the highest performance polymer piston head on the market. 

• Delrin CNC machined
  Very low coefficient of friction and extremely high impact resistance
• Elongated shaft to allow more AoE spacers
• Grade 12.9 zinc plated screw
  Superior corrosion resistance and trong enough to strip cheap allen keys before the screw gives out. 2mm hex drive
  
• CNC 7075 T6 Aluminum Threads
• Dual Port Design
  Dual porting to reduce vacuum effect and for more usable air volume in high rate of fire applications
• European Manufactured NRB Oring 
  Superior abrasion resistance, better low temperature performance, significantly higher tensile/compression strength and lower compression set compared to Viton/FKM. Viton is a lie.
  
• Bronze (6g) and Delrin (1g) Bushing Included
  USE ONE OR THE OTHER ONLY - Lightweight Delrin for when you want to go fast or heavy Bronze for when you want to sling heavy weight bbs. (Total Weight: 7-11g)
