Well I did it again, I was sure I had seen someone do a good job of mounting the 03 front sight on a barrel by filing a step. Thought it was BR, and I could not find the thread, then thought it may have  been carbonoutlaw as he has been posting some well done hand craftsmanship lately. Could not find it either, perhaps it was on another forum or I just dreamed about it.
