Prometheus 6.03mm EG Barrel 275.5mm HK416D Next Gen

This inner barrel is the heart of your AEG's shooting performance. The barrel guides the BB from the hop-up unit to the exit of your replica and largely determines the consistency and range of your shots. You replace an inner barrel when you want to improve grouping, achieve more consistency in your shots or when your current barrel is damaged or fouled. An airsoft inner barrel upgrade such as this Prometheus barrel is often one of the first upgrades that tech-minded airsofters carry out.

Technical characteristics

This barrel is manufactured from stainless steel with an inner diameter of 6.03mm and a length of 275.5mm. The silver finish is characteristic of the stainless steel material. The tight tolerance level of 6.03mm ensures good air seal around the BB during the shot. The barrel has a standard AEG window cut-out for the hop-up rubber and fits in the hop-up unit of Tokyo Marui Next Generation replicas.

Compatibility and application

This inner barrel is specifically designed for the TM Next Gen platform, particularly the HK416D. The barrel fits directly into Tokyo Marui Next Generation replicas without modifications. For installation, basic knowledge of AEG disassembly is required - you must be able to access the hop-up unit and replace the old barrel. This upgrade fits both standard builds and advanced setups where consistency and grouping are important.
