For your consideration , I have a Ruger American ranch rifle in 7.63x39 that is a great shooter even with Russian steel cased ammo. It accepts Ruger mini 30 magazines so 5, 10, and 20 round magazines are available, it is threaded at the end of the barrel, so I ordered the flash hider for the Ruger mini 30, I put a leupold 2x7x33 scope on it. Since I got 5 other guys at the club have bought the same gun.
