6.03 Inner Barrel | 113mm | GBB | TTI

6.03 Inner Barrel 113mm TTI – inner barrel for your replica

This inner barrel is the heart of your Hi-Capa pistol and determines how consistently your BBs fly. With an inner diameter of 6.03mm you create a tighter airflow around the BB, which ensures a more stable flight and better grouping. You replace this barrel when you want to achieve more precision from your pistol or when your current barrel shows wear. An airsoft inner barrel upgrade is one of the most effective ways to improve your replica's performance.

Technical specifications

This TTI inner barrel has a length of 113mm and an inner diameter of 6.03mm. The material ensures a smooth internal finish that minimises friction.
