Red and green and a circle to boot! - Leapers UTG 3.8in ITA Red/Green Circle Dot Sight w/Integral QD Mount

Mounted it on my Bushmaster M4A3. Needed to add a 3 slot 1/2" riser (UTG MNT-RS05S3) to see over my front A2 sight. Now it co-witnesses 1/8" above my BUIS which is perfect.
Bright enough for Florida sunshine. Larger field of view and MUCH easier to find the reticule then my Bushnell TRS-25 red dot. The circle makes a BIG difference when speed of target acquisition is important. Also, doesn't have the red reflection off front lens like many others.
Even with the cost of the riser the price is ridiculously low for such a quality optic. The only thing I would change is better low-light adjustment. It's a little too bright on a moon-lit night. (But then that's why I have a laser too.)

Try it, you'll like it!
Pros: Just the right size, very bright reticule, flip covers
Cons: May be a little too bright at night
