My grandpa just sent me a Mossberg 535 with a rifled slug barrel and a turkey barrel (no turkey choke though, just a modified). The package got really banged around during shipping and the sights on both barrels were damaged.
The rifled barrel currently has an adjustable rifle sights on it, dovetail front and back. The turkey barrel currently has adjustable fiber optic sights that slide onto the vented rail (not sure what else to call it) on the top of the barrel.
Can you recommend replacement sights for me? I really like the sites that are on it, except that I think I would like a fiber optic front for the rifled barrel. I would also like to have a front bead fiber optic site (or something else) for when I am using the turkey barrel for other types of shooting and don't need a rear sight.
I live for others and I answer to God and sometimes to my wife too.
I will try midway or brownels.
Good luck with Mossberg Customer service. They have yet to return several of my email inquiries as of late.
Now, we must all fear evil men. But there is another kind of evil which we must fear most, and that is the indifference of good men.
