it may be easy, but i have never worked with internal parts on a gun. i can install pistol grips, buttstocks, forearms/handguards, and the like, but as far as a saiga goes, drilling out rivets and removing/replacing internal parts is beyond my comfort zone. if there is someone on this site who lives in or near hampton roads who knows how to install a saiga trigger, i would greatly appreciate your help and will pay for your time.
