A scalarworks mounts and whatever optic you choose would be a great combo for your M2. Red dot and reflex sights just makes sense on a shotgun in my opinion. I trust holosun per my own experience but there are other great options out there. Just get whatever fits your taste and budget. The good thing about the scalarworks mounts is that they are low enough to co-witness. So if your optic does crap out (and they ALL can) you can still use your irons. I put an XS big dot tridium front sight on my M4 so if my sight does crap out I can still clearly see my front sight through the optic. Not a great pic but you get the idea.

Thank you John Doe, NCswamp13, I included two photos of my M2. When I wrote scope above, I should have written Red Dot. I am not entirely sure about what questions to ask, but I thought that I could use a Red Dot to visually pin my target and then see how far off my shooting is... The barrel length is 18"...I have not yet removed the shell blocks. I super appreciate the help!

Just throwing my 2 cents in on the original topic. I have holosun HE507c-gr x2 on my M4 and the holosun Paralow HS503G on my M3. Both on scalarworks mounts and they've been rock solid. I turkey hunt with the M4 and the M3 is my "Slug gun". So they mostly get fed pretty potent loads.
