The Karabinek-granatnik wzór 1960 (Polish: Carbine-grenade launcher model 1960), also designated PMK-DGN-60[1] or PMK-60,[2] is a Polish-made version of the AK-47 assault rifle that can fire rifle grenades.

The LON-I grenade launcher is screwed onto the forward end of the rifle barrel and locked into place by means of a spring-loaded plunger mounted in the front sight base of a modified AK-47 rifle.

When using the rifle to launch grenades, a special rubber recoil pad is used and a special 10-round magazine is inserted.

[2] This magazine has a filler block that prevents it from being used with "normal" (i.e. bulleted) cartridges.

There is also a regular version of this rifle as well that was not designed to shoot grenades.
