I have a 182 series Mini 14, I had to have the barrel replaced because it was damaged. The barrel I got was a stock stainless steel barrel with the front sight already installed. Once the barrel was installed the front sight was canted to the left a little. I wanted to replace the front sight anyway, so its no big deal. What I need to know is, is removing the factory front sight easy to do once to remove the roll pin holding it in place ?.
