LayLax Prometheus x G&G EG Inner Barrel

This specific barrel is designed for the G&G CM16 SRS series. While it may physically fit other AEGs with similar hop-up units, we recommend verifying your specific rifle's barrel length and hop-up compatibility before installation to ensure proper feeding and air seal.

The 6.03mm diameter is considered a 'tight bore' that reduces the gap between the BB and the barrel wall. This minimizes air leakage around the BB, which typically results in more consistent muzzle velocity and improved grouping at longer ranges.

You don't strictly need to, but it is highly recommended. Since you are already disassembling the hop-up assembly to install the new barrel, replacing the bucking is a smart way to ensure the best possible air seal and spin consistency.

Stainless steel is durable and resistant to corrosion, but it still benefits from regular cleaning. Use a soft cleaning rod and a silicone-free solvent to remove any debris or residue from the inner surface to maintain its polished finish and accuracy.

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