Lol!I just went on muellers website to check it out.That MX looks and functions like the Ulta-Dot sight,which is a very good red dot sight.I put an Ultra Dot on a 870 slug gun back in 89' or 90' and the thing is still going strong!Sold that gun to a friend,who sold it to another friend who still has it.Neither of them are particularly easy on equipment,it's accounted for a lot of deer over the
years.So if the Mueller sight is based on the Ultra dot design i would imagine it would be good.Alot of guys were running mueller quickshots and loving them a little while back,maybe some of them could chime in and update how their holding up.I been wanting a burris ff for a couple seasons now but i'm like you,just can't swing it this season.Hopefully next season ff3 or even looking at the tac30,gives me something to daydream about this summer lol!......ward
