870 drill & tap for optic.

Looking for proven, reputable source to have my wife’s turkey gun drilled, tapped, and optic rail installed. Unfortunately it’s a late 90’s model and will need a gunsmith.

I’m planning on putting a different stock on it to raise her cheek up also. REM has an OEM option that I’ve seen.

Thanks in advance for ideas.

Al Greco of Al's Custom in Pennsylvania still does shotgun work I believe. Here is a link to his website: "https://www.alscustom.com/". Hopefully that helps.
