16" Carbine length M72 Yugo RPK Black Nitride Barrel

These are custom M72S RPK barrels designed by AK-Builder for AOA that still allow for bipod installation. Unlike the standard model from AK-Builder, which does not accommodate a bipod, this version features a slot for easy attachment. This design offers flexibility—you can build your RPK without the bipod and still have the option to add it later if you choose.
