Laylax Nine Ball Power Barrel Inner Barrel

This barrel is specifically designed for Tokyo Marui AEPs and models that share the exact same internal specifications. If you are using a clone or a different brand, verify that your pistol uses the standard Tokyo Marui AEP barrel dimensions before purchasing.

Yes. Because of the extremely tight 6.00mm bore, you must use high-quality, polished BBs to prevent jamming. Avoid budget or low-grade BBs, as any surface imperfections can easily cause a blockage in such a precise barrel.

The stainless steel construction provides significantly more rigidity than standard aluminum or brass stock barrels. This reduces barrel vibration during firing, which helps improve your grouping consistency and overall shot accuracy.

Installation is generally straightforward if you are comfortable field-stripping your AEP. You will need to disassemble the slide and hop-up unit to swap the barrels, but it does not require permanent modifications to your pistol.

Laylax intentionally leaves the interior uncoated to maintain the strict 6.00mm tolerance and prevent any potential flaking or uneven buildup over time. This design choice prioritizes consistent air seal and long-term reliability over aesthetic finishes.
