I did some research and what I found was that Mossberg began factory drilling and tapping the receivers in the year 1997.Both of mine came from the factory drilled/tapped, and I was under presumption that all 590s were. However, I was discussing this with an aftermarket accessories manufacturer who has found at least one example with a different hole pattern, and it may have been drilled/tapped after leaving the factory.
When I looked up my serial number for my 590 Mariner, it indicated that is was made in ‘95. But I could have made a mistake.Thank you for that information. I don't know if the 590 series was introduced before that time.
Mossberg started drilling and tapping receivers in 1990-1991.I did some research and what I found was that Mossberg began factory drilling and tapping the receivers in the year 1997.
Holy moly. That means my 590 is older than me...Mossberg started drilling and tapping receivers in 1990-1991.
I just got a 590 Mariner and it was not drilled and tapped. Must be an old one.From what I've read around the web there were some early receivers drilled and tapped...?????
Sometimes Mossberg has done some things nobody could figure out. ;-)
I don’t want to post the full number. Do you just need the end?Serial number?
Lol, so everything except the last one hahaFirst 5 will do.
