I recently installed this M2 Aimpoint on my MP...I have ordered the low mount for it and I do believe it will be just fine. A 1/2" lower will be spot on for me. The legendary near indestructibility of the Aimpoint was a factor. Plus I have one on a Krink that I like a lot.
I mounted a Millet red dot on an MP5SD and I like it a lot too.
