This tool is the cats ass!

If it is one job, send the barrel out.

Thanks, for the link to get an idea of the jig to build. Is making a jig the only sure way to do  it?

What I do to install a FSB on a barrel is assemble the barrel to the upper. I then put the upper on a completed lower.  I take the FSB and put blue locktite on the inside of the bottom of the FSB and slide the FSB onto the barrel.  I then turn the rifle upside down so it is resting on the front and rear sight. I tap the FSB and make sure it is flush with the barrel. I let it dry overnight. I then check the sights to see if there is any degree of misalignment.  If it looks good, I then take it out to my mini mill and clamp the FSB in the vise. I use bubble levels to make sure the rifle is level front to back, and side to side. I drill the holes in the FSB and then ream with a 2.0 taper reamer until the pins fit.  So far I have done about 8 barrels that way without any real alignment issues.

I have some epoxy onsite so I got it assembled coated the ferrules and  slid the sight on slid in a  rifle gas tube and clamped it to the bench  looks pretty damn straight,  I am thinking a few days to totally set up the drill on the drill press from either side.
Thanks for the advice
