Very satisfied solid - Sightmark Ultra Shot Plus 1x 4-Pattern MOA Reticle Red Dot Sight

I have experimented with 5-6 different red dot sights, sight mark in my opinion for the money is right on. I have some negs. and pros. along with some information I wish some could have answered for me.
1. this sight co-witness perfectly for those of you that have an AR-15, couldn't get an answer on that from anyone.
2. the battery compartment is perfect, water proof and has a attachment so you don't loose the cap.
3. operation is simple and easy to operate.
4. the multiple optics are perfect, even when you switch from one to another it keep zero.
5. IT KEEPS ZERO.
6. someone at sightmark needs to figure out that the QD Lever needs to be refigured, it sticks out to far, has gotten caught on my gear, I'm a tact officer. Had to use a large rubber ban to keep it from snagging.
7. find some way to shorted the length so a magnifier can fit on the main portion of the top rail.

I love this sight, have strongly recommended it to my other officers, other than an EOtech it's right on.
