I have a 1970ish mossberg 500a. The stock, reciver and internals are ok but the old barrel is shot. Will I have any issues installing a new barrel? any big part changes over the years?

Thanks

I have a 20 gauge Mossberg 500 from the 70s and I cant see any difference between the barrels it came with and the ones they offer now so I don't think the 12 gauge would be any different.

I have a 500a. Replaced the barrel a couple years ago. No issue at all.
Good luck

I just stuck a new barrel on an old receiver... Seems to fit just fine

The barrel from a Maverick will also fit . This is a Maverick Receiver with a Moss 500 barrel.

If it is for slugs ??? Do not tighten barrel nut down, leave it a click lose, so barrel floats, so to say. If smooth bore.
