I gotta share this love.
I bought an Aimpoint COMP ML back about five years ago and it lived a happy life on my carbine seeing lots of good use across three states and several thousands of rounds. It took a turn for the worse about four months ago when the LED went really dim. I sent it in, Aimpoint repaired it for free and returned it very quickly.
About a month ago the sight went bad again with the same symptoms.
I returned it last week for repair and tonight UPS delivers a brand spanking new in box Comp ML2. Ain't that what you gotta call customer service! A company that stands behind a five year old sight like that is top notch in my book. No complains, no questions, no excuses just good service.
