This is such a high quality sight well worth the money also the red dot sight with 65 moa is so clear and crisp with the magnifier. Also fast shipping came here 4 days before expected!!I did my research and didn't want to spend 1500 on a Trijicon with had a glowing rectal that never turns off,it uses some sort of chemical (tritium I believe) for illumination for its rectal. So what happens when the chemical runs out? Also some models have a small red dot sight on top of the sight in which you have to pay extra I believe for and you can't quickly switch fast from close to far engagements. It just wasn't my style and it makes it look like a "mall ninja" gun (tacky). Also the Aimpoints were another option I considered but it limited my field of view and look really fragile and small, you also have to buy a mount for them as well! So I then got and eo tech and fell in love it was great it had a "TV screen" style field of view meaning I can see more of my surroundings than the Aimpoint, ability to quickly switch between close and far sight with a flick of the wrist, and was in my price range and very durable with plenty of protection and ran on a cr123 battery which I can go to a store and get. Also included quick detach mount which was awesome and feels like it is well built and won't snag stuff it also has a safety feature so you don't unlatch it by accident and you don't drop expensive sight on the ground. Plus it makes my gun look sick as *&%%!EO Tech once again delivers great quality weapons sights, easy to mount and built like a tank (it just feels so right on the gun). I had the old big model 512, which was a great sight as well but it was to big and I wanted to and a magnifier. I am so glad I purchased this weapon sight. I always wanted my rifle to have close/long range capabilities. I had doubts about the flip to side mount but it is super solid and doesn't wobble when rifle is being fired using only the holographic sight. Also the magnifier is so user friendly and you do not need any tools you can adjust the focus and the up and down left and right to complement the rectal. The button on the holographs sight to adjust between the hundreds of settings you can pick from is conveniently located on the side for easy access and has a night vision mode. Also the bullet drops works great if you know what your doing and use the right kind of ammo. But it is a little blurry when you only use the holograph sight without the magnifier, but I mostly use the magnifier for any target greater than 50-75 yards. So bottom line and no matter what distance i can quickly adjust my optics for close and distance targets which is what I want. In turn the sight works perfectly for what its is designed for.I have a DPMS lower, LMT (upper) ,16inch barrel with a 1/7 twist,medium contour barrel and standard A2 muzzle. My point of engagements are 50 to 300 yards and I can hit man sized targets with ease. The sight works great everything I expected it is like the jack of all trades in witch the distances I shoot at!!! Fantastic!
