Unicorn 6.03 mm Ultimate Precision GBB Inner Barrel

Unicorn 6.03 mm Ultimate Precision GBB Inner Barrel is a high-quality Nitroflon-coated precision barrel designed for gas blowback (GBB) pistols and rifles.

The Nitroflon coating increases wear resistance and protects against corrosion while reducing friction. This helps maintain consistent performance over time and makes the barrel a reliable choice for active use.

The 6.03 mm inner diameter classifies it as a precision barrel. The tighter tolerance reduces excess space between the BB and the inner barrel, minimizing air loss and stabilizing the trajectory. The result is a more consistent grouping and improved shot-to-shot consistency when paired with a properly adjusted hop-up system.

The barrel is designed for Tokyo Marui standard GBB models and other compatible gas-powered replicas. It is available in multiple lengths. Before ordering, it is important to verify your replica’s barrel length and hop-up chamber interface type to ensure proper compatibility.
