Nozzle | M4 Series | 2021 Version Low Velocity | GHK – for your replica

This nozzle regulates the gas flow in your GHK M4 GBBR and determines how much gas is released per shot. The Low Velocity version restricts the gas flow, ensuring your replica remains below 1 joule. You use this GBBR nozzle when you want to stay within CQB limits or need to comply with local field regulations where lower energy is required.

Technical specifications

This nozzle is made from black anodised aluminium with a durable finish. The 2021 design features improved gas sealing and fits precisely in the bolt carrier group of GHK M4 replicas. The nozzle has standard GHK dimensions and comes with a retaining clip for installation.

Compatibility and application

This nozzle is specifically designed for GHK M4/AR15 GBBR systems and fits all GHK M4 variants with the V2 system. Installation requires basic knowledge of GBBR maintenance – you remove the bolt from the carrier, replace the nozzle, and reattach the clip. The part fits both standard and custom builds where energy adjustment is needed.
