Just purchased a very nice Vixen .223 HB, vintage early 1960's . Came with original Sako rings but the 4 screw heads are in bad shape. Person who was responsible for removing the scope must have used a jack hammer. He knew very little about guns. Good for me, bad for the gun . Too bad, this gun and rings were perfect before the scope was removed. Would like to replace the four screws. Makes me quizy every time I see carnage - Thanks Ron
