I do not like any of the methods used to mount a sight or scope so far on an ak the side mounted scope I hear has alot of proplems they vibrate and come undone while shooting I do not want to put an optic on the upper foregrip eithe rb because I want the sight to be close to my eye I want the ak47 to have a rail buit right on top of the reciever like the zaztava m70pap aks how can I mount an optic on top of a regular ak? Can you drill and tap the top of the reciever and instal a picatany rail? I do not want to buy a reciever with rails built in I dont want to spend extra cash how can I mount an optic on top of the reciever close to my eye?
