The ZRAK ON 2 was used on the M69 sniper rifle. During the later years of Yugoslavia, the Slovenian Territorial Defense force was not supplied with the new M76 rifle. To fill this gap Slovenia developed a scoped M59 (SKS) which included an ON 2 scope modified with a new BDC in 7.62x39. The scope modification may have been carried out by the Tovarna Opticnih Sredstev ("TOS") factory in Ljubljana, Slovenia.
It is not clear what is the exact relation between the ON 2 and ON 2L scopes.Serial | Caliber | Images | Notes |
