For those you looking for a good soild reddot scope, and aren't LEO, Military or "hard use", I would seriously look at the CompC. With the same rugged Aimpoint construction, and the included mounting ring, it is a great value.
It does not include the flipup lens covers like the CompM series, and the battery life is shorter (1.000-10.000 hours dependent on setting. Storage 10 years).
