Just purchased a BCM LW barrel and also a BCM front sight post. I was a little surprised when I saw the sight post because it did not have holes drilled in the sides for tapper pins. Sure enough the website states you have to drill them. However, when I looked at the barrel there were not two groves for the the pins. Instead there was a dimple. I flipped the front sight post upside down and behold, there is a hole under the swivel that lines up with the dimple.
So do I have to drill groves in the barrel and how hard is it to drill the holes for the tapper pins?
