Rare 1958 Polish KBK wz. 1958 Parts Kit – Milled - Underfolder Stock, Type 3, Original Polish Barrel in 7.62x39mm (matching numbers #1704)
“Small Batch” alert: we are first to bring to market a limited run of KBK wz. rifles still wearing their torch-cut Type 3 receivers and intact factory barrels. Every kit is listed individually, so what you see is exactly what you get.
This set is a 1958-dated, Circle 11-stamped Polish AK-47 that left Radom’s famed Łucznik factory before Poland transitioned to stamped AKMs. It retains a matching-number group (#1704) – receiver stub, bolt, bolt-carrier, recoil spring and dust cover all roll-marked alike. The original cold-hammer-forged barrel remains pinned in the trunnion with strong, bright rifling.
KBK wz. 1958 & Polish AK history
KBK is short for Karabinek—Polish for “carbine.” The model code wz. 1958 (“wzór 1958” = “Pattern 1958”) identifies Poland’s license-built Type 3 AK with a machined receiver. Produced in relatively small numbers from 1957-1962, these rifles bridged the gap between the Soviet Type 3 and the stamped-receiver AKM. While most were fixed-stock models, a small number were produced with a milled underfolder stock, making this variant particularly desirable. Because most were rebuilt or used for AKM conversions in the late 1960s, matching KBK wz. 1958 kits are exceptionally scarce today.
