Laylax Nine Ball Inner Barrel

A 6.03mm bore reduces the gap between the BB and the barrel wall compared to standard factory barrels. This minimizes air turbulence as the BB travels down the barrel, resulting in more consistent muzzle velocity and improved shot-to-shot accuracy.

This barrel is designed for standard Hi-Capa platforms, but compatibility can depend on your specific slide length and outer barrel setup. Always verify that your current inner barrel length matches the 112.5mm specification to ensure proper fitment and performance.

No, this is designed as a drop-in upgrade. It should install directly into your existing hop-up unit without the need for filing, cutting, or permanent changes to your airsoft gun.

Yes, it is highly recommended. Because the tolerance between the BB and the barrel wall is tighter, any imperfections or debris on lower-quality BBs are more likely to cause jams or accuracy issues. Stick to high-grade, polished ammunition to get the best results.

You may see a slight increase in FPS due to the improved air seal, but the primary goal of this upgrade is consistency and grouping, not raw power. If you are looking for significant velocity changes, you would typically need to look at spring or gas system upgrades.
