I have a Eurolux scope, when I bought an SKS. Tried it out shooting 5 round bursts, 1 second between each round. I had to re-zero it every time with no improved accuracy, and even worse accuracy. I shot sniper scopes in the military with no problems. Its been awhile, yet I don't think this scope is built for 7.62. I am viewing scopes now to buy and never do I see a Eurolux anywhere. Probably because they are no good.
