I tried to remove the rear sight on my Remington Zoli Zouave. The screw that holds the sight to the barrel appears to be flat topped with 2 indentations. I used the pointed tips of a small pair of pliers, inserting the points into the holes. I was only able to turn the screw approximately 3/4 of a revolution, then it stopped. Is this normal?
