Laylax Prometheus EG Inner Barrel

Yes. The tighter 6.03mm bore reduces the gap between the BB and the barrel wall, which minimizes air turbulence and creates a more consistent shot path compared to standard factory barrels.

This barrel is designed for wide compatibility with standard AEG platforms, including Tokyo Marui, Matrix, and G&P. However, always verify your current barrel length to ensure the 433mm size fits your specific outer barrel assembly.

Stainless steel is highly durable and resistant to corrosion, making it lower maintenance than brass alternatives. Simply ensure you keep the interior clean and free of debris using a standard cleaning rod and silicone-free solvent to maintain its polished finish.

You will likely see a slight increase in velocity because the tighter 6.03mm diameter creates a better air seal, allowing more air pressure to push the BB. However, the primary benefit of this upgrade is consistency and grouping, rather than a massive jump in power.

The high-degree polish reduces friction as the BB travels down the barrel. This smoothness ensures the BB maintains its spin and velocity without being slowed down by surface imperfections.
