Very affordable and worked great on my FX-9 at the range. It was very easy to put on and was extremely accurate when using my 9mm AR. I like that you can change the rectal design and color.

It works great and it feels high quality. It attached to my gun really tight and looks really cool. It also can get adjusted very easy and when you adjust it it is pretty accurate. Would buy again.

I love this red/green dot sight. It’s illuminated and crystal clear. I have it on my Ruger 1022 and it works well. There are four selectable reticles to choose from in either red or green. All and all, a great buy for short money

This product was amazing! I got a new scar l so my friends and I could play Airsoft and this sights is all I wanted and more. I am able to snipe my friends without them even seeing me since I am a distance away. The sight is amazing since it helps account for long range shots. The different sights and colors also help a lot. Some of them are more accurate for long distance and others are create for close up incounters.

IS IT RIGHT FOR ME:If you require a sight that is bright and easy to see in the daytime, and don't have too much money then this is ideal for you.PARTS INCLUDED:This sight comes with a nice packaging and the batteries are included, along with a cotton wipe to keep fog and dust off the lens and in addition it comes included with a lens cover to protect the sight when not in use. With this packaging, you will have a good box protected with foam to put your sight, and the proper protection required without having to buy extra parts for the sight. The only part that you should purchase along with this sight is a sight protector, it is described as a small barrier of clear material that will not affect the reticle or the lens, but it will protect it. These most likely only cost an extra 5 - 10 dollars to protect a 30 dollar sight, far worth it.FUNCTION:The battery screws in where the brightness/color selector is located, the battery is compact and a flat shape so it fits perfectly without hindering your view of the reticle. The reticle is very bright and easy to see in the daytime outside and a less bright setting is suggested based off the brightness of the area you are playing in. The sight will add a small amount of weight to your gun making it easier to move around. The borders of the sight do not limit the viewing area, making it easy to see others around you when aiming through it. The lens also have a small, almost unnoticeable tint.RETICLE CUSTOMIZATION:Customizing the reticle is easy to do on this sight as you simply have to turn a few switches, the one to select the type of reticle is located at the bottom, closest to you, and the one to customize the color and brightness is located where the battery is inserted, closest to the lens. The reticle selector has 4 settings, circle, classic red/green dot, a crosshair created of lines, and a mixture of the circle and line crosshairs. For a smaller reticle, I suggest the mixture since it is a small and compact sight, even though the dot sight is standard on a lot of sights, I do not suggest it as it is the most difficult to see but that is up to personal preference. For a larger reticle I suggest the circle, it is large and very easy to see. For a medium sized reticle I suggest the lined crosshair. It is large yet fairly easy to see where to aim. My personal choice is the mixture, it has a little bit of both while maintaining the small and compact profile.RETICLE COLOR/BRIGHTNESS SETTINGS:There are 5 brightness settings for each color (green and red), I prefer green as it is generally easier to see for me. For indoors, dimed action I suggest a low brightness as if you go in a dim area with max brightness it will be too bright to focus on the target, for night time or generally dark indoors I suggest the very lowest setting. For outside daylight I suggest the 4th or 5th brightness setting. At the end of the day, it is all based off what you think is the best.ADJUSTING:There are 2 settings to adjust the aim function of the reticle, one for the right (can be turned the opposite way for left) and one for up (can be turned down the opposite way). The arrows on which direction it goes are clearly marked so no guessing which way is up and which is down. This is a simple system and I personally find it effective and compact with no over complicated settings.COMPATIBILITY:This sight can fit a picatinny/weaver style rail, just confirm your gun's type of rail before purchasing. You can screw in the sight with the standard screws that attach right on with a good fit, simple and effective.CLOSING:This optic is recommended by me and multiple other reviewers, it has a range of customizable settings and has is a bang for your buck. The optic is surprisingly bright and easy to see, one of it's primary points on why you should purchase the optic. At the end of the day, this is simply my opinion and you are 100% free to select your own choice of optic. Whatever that opinion is, I hope you have a great day and I wish you luck on selecting the right optic.

I would recommend this for a .22 rifle but not for a handgun because of blurry and parallax issue beyond 5"Although it 'techically' has 'unlimited' eye-relief (you can see the dot at any distance away from it) the dot (or reticle) becomes too distorted and blurry to use if viewing beyond 5" (especially all the larger shape reticles).Again, that is no problem if on your rifle, but for a handgun (with my arm extended) it is a blurry mess.Otherwise, this optic is clear (and not too tinted!) and actually looks great at 3-5" from the lens, but then anything beyond that distorts and enlarges the reticle unusable. I own many other reflex sights of this style and I don't have this issue at arms length. Perhaps I just have a bad lens on this one (the lens looks wavy at even the slightest angle, so it is possible it is either a wavy lens was installed at an angle).I am still deciding if I should bother to mount it, or contact the Mfr, or return it.

I put this on an Extar EP9, which is a 9mm AR platform pistol with a brace. The optic failed before I finished a box of ammo. To get it to turn on for green, you would have to balance it between two settings. If you toggled to red, it would tend to stay on, but would go off every once in a while. This may work with an airsoft gun, but not a firearm. A 9mm has little recoil in an AR platform, so if it can't handle that, I can't imagine it handling anything beefier.

This red dot sight was exactly as advertised. I mounted it to a 12 Ga. tactical shotgun, but haven't had a chance to sight it in yet. It feel very sturdy and made from quality materials. My only complaint, and it is minor, is that there is a slight halo around the sight no matter which reticle i use. Since this is on a shotgun it won't bother me much, though.
