The Polish Westernization of the PKM - The UKM-2000P/UKM-2020S

Summary

Poland has extensively modernized its Soviet-era PK series machine guns, transitioning them to NATO standards. This began with the UKM-2000, developed from 1998 and introduced around 2005, which redesigned the feed system for 7.62x51mm NATO and M13 links. The latest evolution is the UKM-2020S, manufactured by Zakłady Mechaniczne Tarnów, building on earlier upgrades like Picatinny rails and improved ergonomics.
