Laylax Prometheus EG Inner Barrel

The Prometheus EG barrel is designed for broad compatibility with most Tokyo Marui-spec AEG rifles, including brands like Matrix and G&P. However, you should verify that your rifle's current barrel length matches the 247mm specification to ensure proper fitment and performance.

A 6.03mm bore is considered a 'tight-bore' barrel. By reducing the gap between the BB and the barrel wall, it minimizes air turbulence and creates a more consistent air cushion, which directly translates to tighter shot groupings and improved accuracy at range.

Stainless steel is highly durable and resistant to corrosion, making it lower maintenance than brass alternatives. You should still clean the bore periodically with a soft, lint-free cloth and a small amount of silicone oil to remove debris and maintain the polished finish.

Yes, you will likely see a slight increase in FPS. Because the tighter 6.03mm bore creates a better air seal around the BB, more of the air volume is used to propel the projectile rather than escaping around it.

Absolutely. Because of the precision 6.03mm tolerance, you must use high-quality, polished BBs to prevent jams. Avoid budget or low-grade BBs, as any imperfections or inconsistencies in the BB surface can cause them to catch inside the barrel.
