Yeah I don't think I'm gonna be going scuba diving with my AR so that's not an issue. I'll consider the C3 over the M4 because of the price and I'll probably get the C3 before I get an EOTech XPS just because Aimpoint is better than EOTech. I'm really leaning towards an Accupoint TR24G w/ a cattail though. And I would love to get a Micro H-1; I love the size, weight, and mount but I just don't like the 4 MOA dot. I'll probably get one for my future SBR though.
