Can anyone tell me how to drill and tap for shotgun bead sights.  This would be for a plain barreled gun, not vent-rib. I'm considering trimming some barrel off a single- shot gun and I want to keep the bead.  Would it be better just to try a snap-on or glue-on sight?  Any links or information is appreciated.

Thanks,

First off, do you have a drill press?

Have you ever drilled and tapped anything before?

If you answered "no" to the first two questions, you would be better off taking your barrel to a gunsmith or someone with a drill press and expierence in drilling and tapping hole in metal.

i love my true glow sights.
much better than a gold bead!

Rambosky's right. Plus, it's very easy to get it off center. You need someone else to blaim if that happens.

The Threads on the beads are either 6-48 or 3-56. These are not standard thread sizes, so you would have to pay for the tap, drill bit and shipping.

Just pay the starving ole gunsmith the $20 he's gonna charge and be done with it.
