Leaning towards a Burris myself
There are only a handful or red-dot manufacturers that are more or less bombproof on a hard-recoiling field gun, especially over the course of years. I run them hard on handguns especially. Best recommendation I could offer would be a Trijicon RCR (enclosed is a very good idea for a field gun, as opposed to an open emitter, which can mud, snow, etc get into it and block the laser), or an Aimpoint of some flavor. They're also the least likely to show any bloom to the dot from what I can tell. If you don't have any astigmatism at all, you might find good luck with Holosun too, which are notably cheaper, and hold up well for a lot of guys in the competition world.
