The HK45 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.
