Thread lock (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 Piston. 😂

The Whisper is about to be the highest performance polymer piston head on the market.📈

✅Delrin CNC Machined
Very low coefficient of friction and extremely high impact resistance

✅As Durable as Aluminum
While granting all the benefits of a polymer piston head.

✅Elongated to Allow More AoE Spacers

✅Grade 12.9 zinc plated screw

✅Strong 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.

Did you know you could use a GBB output valve key to tighten our cylinder head shaft?
