Ive got an SBE2 12ga and an M2 20ga set up identically. I set up the M2 for my son a few years ago. Both have been coated/dipped with Burris FF3s mounted.

I planned to switch to the 20 full time this year but have decided instead to use up the Federal 12ga turkey shells I have. When they are gone I may sell the SBE2

The M2 20 with red dot is about a perfect turkey gun. That said, I’ve got an urge to see if a CZ Bobwhite All Terrain S/S 20ga could work. May give it a try next time I have some down time but concerned about the barrel hitting to the same POI or close enough
