Laylax Prometheus EG Inner Barrel

The 6.03mm bore is considered a 'tight-bore' specification. It minimizes the gap between the BB and the barrel wall, which reduces air leakage and creates a more consistent air cushion, leading to improved velocity stability and tighter shot groupings.

No, this is not a universal part. You must ensure the 310mm length is compatible with your specific outer barrel length and that your rifle uses an AEG-style hop-up unit. Always measure your current inner barrel before purchasing to ensure a proper fit.

Stainless steel is highly durable and resistant to corrosion, making it easier to maintain than brass barrels. However, you should still clean it regularly with a soft cloth and silicone-free lubricant to prevent debris buildup that can degrade accuracy.

By reducing air turbulence and ensuring the BB travels down the barrel with less 'bouncing' against the inner walls, the barrel allows for a more consistent hop-up application. This results in a flatter, more predictable flight path, which effectively extends your reliable engagement distance.

While not strictly required, it is highly recommended. Installing a new, high-quality hop-up bucking alongside a precision barrel ensures a perfect air seal, allowing you to get the maximum performance benefit from the upgrade.
