Rare 1961 Polish KBK wz. 1961 Parts Kit – Milled-Receiver Type 3, Underfolder Stock, Original Polish Barrel in 7.62x39mm (matching numbers #16537)
“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 1961-dated, Circle 11-stamped Polish AK-47 that left Radom’s famed Łucznik factory near the end of milled production. It retains a matching-number group (#16537) – receiver stub, bolt, dust cover, and recoil spring are roll-marked alike, and the bolt carrier features an authentic factory restamp to match. The original cold-hammer-forged barrel remains pinned in the trunnion with strong, bright rifling.
KBK wz. 1961 & Polish AK history
KBK is short for Karabinek—Polish for “carbine.” The model code wz. 1961 (“wzór 1961” = “Pattern 1961”) 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, matching KBK wz. 1961 parts sets are exceptionally scarce today.
