||I got this sight for my M4 stubby, and so far, it's great.
-huge field of view
-The lens coating is such that there is barely any darkening when you look through.
-long battery life
-bright and clear dot
-The laser projector is on the right side, so the dot warps as you move your eye to the left. I believe it should be on the top, although I can see why that wouldn't work.
-The dial is a little tough to turn. this could also be a pro, since to me it's only a minor inconvenience.
-At night you can see the projector despite the lens coating.
-The sight itself has a slightly different appearance than in the pictures. These differences are: The mount's thumb screws are on the left, and the dial has no colored numbers.
-This is a pretty large sight, so I wouldn't put it on something too horribly small.
-You can actually use the front of the sight to aim around corners. If you look, you can see that the projector, when sighted in, actually points out where the gun is pointing.
-I never use the green dot; it takes up more battery life and at times is harder to see, and see past.
I definitely recommend this sight due to its quality and price.
