The G18C AEP Stainless Steel barrel from PDI Japan represents the finest level of AEP upgrades on the market.

It is our go-to barrel for all AEP builds due to the tight but consistent inner bore and the extremely reliable tolerances.

PDI Steel barrels are cold hammer forged with a polished crown and an average sized hop window. The tighter bores are ideal for improving the cylinder to barrel air ratio to maintain energy output with heavier ammo.

  • Compatible with Tokyo Marui and Cyma brands of G18C AEP as well as their clones. 

    Some batches of Cyma AEPs may require some modification to the barrel to fit with the original hop rubber. 

    Ideal when paired with the PDI W-Hold AEP hop rubber.
