This is my first red dot scope and just put it on my M4 for a battle today and it is SWEET! I have plenty of friends who have red dot scopes or sights and this is by far the best. The lens covers and solid and pop up real smooth, and the red dot is a gorgeous dot. I always used brightness 7 (the brightest one) but the dot lined up perfectly with targets so BB's were on target all the time. I noticed a huge improvement over squinting through my iron sights. The best thing about this was how I could aim with both eyes and the dot lined up. It also fit right on, comes with an extra battery and is overall high quality, just a little heavy for a scope. Some people may need to buy a riser, but I liked how the dot lined up with the front iron sight. Overall, a great buy, especially when compared to all the other $100 scopes on this site.
Great, strong build
Small, bright, pinpoint red dot
Fits on rail, no wobble
HUGE, easy to look down and find targets
A little heavy
May require a riser
