M&P Sport II and Red Dot Absolute Co-witness Assistance

[Scrod314]

Hello...I recently inherited an M&P15 Sport II. I want to put a red dot on it for absolute co-witness, as I have another rifle set up like that. I used a 1" riser on my other rifle and mounted a TRS-25. I'd like to put a Holosun 507c on the M&P15. Do I need a riser for the Holosun 507c to absolute co-witness? The M&P15 currently has Magpul flip-up, adjustable metal sights. Can you guys give me some red dot options and tell me what parts (risers or anything else) I will need to absolute co-witness with my current setup? Thanks in advance. You guys are awesome.

Can't comment on the quality, but found this that says it will bring you up to an absolute cowitness with that model red dot.

There's also this one from American Defense:

And this from Midwest Industries:

Any Trijicon RMR pattern riser that says it's absolute cowitness SHOULD work.

Thank you. Probably going to pick one of the more expensive ones, as I didn't pay anything for the rifle except the FFL transfer.
