targets at up to 400 meters at night), PKT (PKT), and the GROM or “Thunder”
(pintle-mounted PKT with a manual trigger intended for naval and static
applications). All the models produced have their iron sights illuminated by
tritium light sources.
• Romania (RomArm): PKT (PKM) and PKMS (PKMS). There is also a PKA
(unknown which version–likely PKT) for aircraft installations.
• Yugoslavia (Zastava): M84 (PKM) and M86 (PKT). The M86 may be found in
three different versions. 1) The coaxial gun for the M84 battle tank,which has a
fixed heavy barrel and a remote-control solenoid firing mechanism. 2) The
externally mounted commander’s gun, the M86A, also has a solenoid firing
mechanism and a rapid-change barrel. 3) If required, the M86A can be used
dismounted. When dismounted, the firing solenoid is replaced by a manual
trigger group and pistol grip, combined with a rudimentary butt.
Development work has been conducted by several countries to produce corresponding
versions of the PK machineguns capable of firing 7.62x51-mm NATO ammunition has
been completed. This was done primarily to exploit the export market and to meet
NATO compatibility of new NATO members. Known caliber conversions are:
• Bulgaria (Arsenal): MG-M1 (PKM) and MG-M1S (PKMS).
• Poland: UKM-2000 series, UKM-2000P (PKM), UKM-2000D (PKMS), and UKM-
2000C (PKT).
