Drill and tap

[jerf]

Local gunsmith told me he could drill and tap my h/r topper 12 gauge safely, he is going down through the chamber and going to use red locktight to make it permanit is this ok, pretty sure he would not risk his livly hood.

It's fine if it's gonna be perminant.
You need to heat that area up to break it loose if ever decide to do so. This will save you from stripping out the screw heads.

Getting a bushnell trs-25 put on it.

No one else has any advice?

I would ask him to try not to into the chamber.  I have seen it cut holes in the shell before.  Now if he lets the screw go into and sands it flus with the inside of the chamber you should be fine.

He said he would file them flush.

  Got my gun back today and could not be happier, Gunsmith did a great job.
