Drilling and Tapping Mossy 500

[wjh2657]

Does anybody know of any difficulty in drill and tapping a ca.1983 Mossberg 500 for a Weaver scope mount? I have heard rumors not to tap because of aluminum receiver. I have the right mount from Weaver but will need to take to gunsmith (some distance away) for drilling and tapping. I sort of want to be sure before I destroy gun and I have had gunsmiths do the wrong thing before. I don't want side saddle mount, so don't even bring it up.

It's not going to be a problem unless your 'smith is a goon.

I D&T'ed mine myself.

I too had the concern of an alloy receiver and putting screws in it. I tapped mine with a .003 undersize tap first, then tapped with a standard tap. That way I got a good thread depth without wollering out the hole. I have a ghost ring sight on mine, but I wouldn't be concerned with a scope or a red dot or what have you, as long as the guy does his job right. A little red locktite and ur good to go:up:
