I am considering buying a double barrel for my MX2000. Is there an adjustable rib double barrel made for the 2000 that will match up with my existing unsingle barrel?
I do not want to have to move the comb when I change over from the unsingle to the double. There are so many options I am getting confused and I thought that the collective wisdom on TS could help me out.
Thanks,
Doug

My wife shoots a double barrel MX2000RS and her barrel set has four notches for adjusting the rib. (Some Perazzi ribs have 5 adjustment notches, but hers is not one of them.)

One thing you need to consider is that the forearm for the double barrel set is different from the forearm for the unsingle. Part of the difference is in the width of the opening for the barrel, but there may be more to it than that. I was told that adding an unsingle barrel to my wife's MX2000 would require some change in the forearm, and I confirmed this by trying to put my MX2005 unsingle barrel on her gun. It wouldn't work - the gap in the forearm for her gun was too narrow to accept my unsingle barrel. Maybe the reverse is workable, since the unsingle barrel is wider, but the forearm might rattle around.

Bottom line, be sure to check that your forearm will fit before committing to buy a double barrel for your gun.

The RS rib will be too high for your 5 notch unsingle.

The only O/U with "low" adjustable rib is the 3 notch MX-2000/3 barrel, but it's still too high compare to your rib. Perazzi made the MX-2000 unsingle not intended to be a matching combo. You'll have to adjust the comb.

Doug, Steve is correct in that the MX-2000RS rib is higher than the MX-2000 rib, but that may suit you fine. It all depends on how high you like your POI for singles and caps vs. doubles.

If you like a higher POI for singles/caps as I do, and a lower POI for doubles, adding an MX02000RS O/U barrel might make your "combo" shoot exactly where you want for each discipline without having to move the comb for each event.

Shoot whatever O/U you are considering with your existing comb setup and see how you like it. Wish I knew then what I know now the last three times I made a "combo".

BTW, you really, really want to consider barrel lengths in the equation. If you shoot a really low POI, it doesn't make much difference. If you like higher POIs, you will be amazed at how different a 35" barrel and a 31.5" O/U barrel shoot with the same comb setting. NOTHING is the same.

I think Steve will agree with my thinking here.. The 5 step MX2000 is really a MX15 height rib.. While the MX2000/3 is the closest.. If one might look at the MX8 step rib barrel or the MX14.. you might get what you want..
I also must agree with ZZT when he said.. the barrel length and YOUR style has alot to do with what will work for you.. and what will not.. When I was at the GRAND working for Giacomo Sporting.. I'd see people come in with a MX15 and try certain barrels.. Some would never work for some shooters.. yet another shooter would try the same barrel and love it.. It's really a question that can't be answered on a keyboard.. You'll need to shoot it.. Mike

Yes, the 5 notch MX-2000 unsingle and 6 notch MX-15 unsinlge barrels are approx. the same hight. Which is not a high rib from an O/U stand point. The MX-2000/3 three notch rib is definitely higher than that, but it's the closest you can find on Adj. rib.

The MX-2000 unsingle will most likely match well with MX-14 O/U but it's not adj.
