Rare 1958 Polish KBK wz. 1958 Parts Kit – Milled-Receiver Type 3, Underfolder Stock, Original Polish Barrel in 7.62x39mm (Non-Matching #1941)
“Small Batch” alert: we are first to bring to market a limited run of KBK wz. rifle parts sets 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 built around a receiver stub serialized #1941. A "builder's special," this kit features a mix of genuine, non-matching Polish surplus parts from the famed Łucznik factory. The original cold-hammer-forged barrel remains pinned in the trunnion with strong, bright rifling, making it an excellent foundation for an authentic build.
KBK wz. 1958 & Polish AK history
KBK is short for Karabinek—Polish for “carbine.” The model code wz. 1958 (“wzór 1958” = “Pattern 1958”) identifies this specific production year of Poland’s license-built Type 3 AK with a milled-receiver. These rifles were part of a series produced in relatively small numbers from 1957 until the transition to the stamped-receiver AKM. While most were fixed-stock models, a small number were produced with an underfolder stock, making this variant particularly desirable. Because most were rebuilt, taken apart for spares, or used for AKM conversions, KBK wz. 1958 parts sets are exceptionally scarce today.
