Back in the day, when I worked in Iraq, I encountered a lot of guns that I could not identify right away. They all had "P" on the rear sight and "SAR" on the selector. All signs of a Romanian made AK. But it had a crutch and arabic numbers on the trunnion. Later I realised those were Egyptian weapons.
Why a lot of Maadis have ROMANIAN markings on the selector and rear sight?
