I have the B-square with the Simmons 4X shorty scope. Its a combination that cant be beat. You can use strippers and there are no dings from the ejected casings. I cant see using a longer scope that gets in the way of the guns action. The only drawback is that the scope needs to come off to disassemble and clean the rifle. I've only done that once and I didnt have to readjust anything. It was zeroed in perfectly. I've said it before on this forum....that scope on the SKS makes me a darn good shot. Its the most accurate rifle in my arsenal but it wasnt that way until it was scoped.
