BCI PKM/UKM-2000 Outer Barrel - AERIS Series

Transform your PKM build with the Bull Craft AERIS PKM/UKM-2000 Outer Barrel—a lightweight, high-strength upgrade made to mirror the Polish UKM-2000 platform. Originally developed from a direct customer request, this component brings loadout authenticity with Bull Craft precision.

Like all BCI parts, it’s SLS 3D printed from Nylon12 powder for rugged durability and minimal weight—built to perform and built to last. While the photo doesn’t show it, each barrel includes a CNC-machined 14mm CCW aluminum thread adapter, standard across the AERIS line.

Authenticity meets innovation. For builds that stand out and hold up.

Built Light. Ready to Fight.
