Good morning fellow gun enthusiasts. I looked in my gun cabinet and found in the back corner my old Chinese Norinco SKS. It is the full size not the paratrooper. It is very very accurate but over these past years my eyesight has been failing and now I need to scope the thing. The rifle will reliably hit a pie size plate out to 550 yards. That is the farthest at the range. But now I can't see much past 50. How should I scope this rifle? Thank you in advance.
