||I bought this red dot with high expectations and it performs quite well. Only a one gripe that bothered me. There is a very small screw that needs to be tightened AFTER you adjust your sights. Other than this, the optics are solid. This red dot is the best one I've used in my nine years of playing airsoft.
Pros: Great for outdoors day time. Its a little too bright for night time use.
Two color options AND 4 really awesome reticles. It has these reticles: dot [ . ], dot with two arrows [ _._ ], a chevron [^] and a semi circle with centered dot.
Stays on target no problem (if using precision ammo)
Very strong glass, It took a direct hit from another rifle (350 fps w/ .20 bbs @ 25 feet) and it only chipped off the reflective coating. Luckily it was on the upper corner out of the way. I highly recommend getting a protective shield. http://www.evike.com/product_info.php?products_id=30845&-
Easy and quick to sight in (took me about 20 rounds)
Includes a battery in the sight, and one in the packaging.
Cons: A bit on the pricey side, but worth it!
Needed to tighten a small screw to prevent wobble.
Overall, very impressed. 9/10
