The PK-01V (ПК-01V) is another red dot sight from Belarus made by BelOMO (БелОМО). It is a modern, mil-spec, light scope simple in design and construction used by both military and police forces. Due to its relatively cheap price but good performance it also enjoys great popularity on the civil market. It is particularly reliable and sturdy like most Belorussian sights.
