Red Dot Optics are great for target acquisition. They allow you to take aim while keeping your target in sight and you can keep both eyes on your target. As long as they are calibrated correctly they are easy to use and a lot of fun. There is something satisfying about seeing a bullet hit the exact place that the red dot was. 
     Red dots work by reflecting an LED light onto a specially coated, slightly angled, piece of curved glass. The special coating allows only the LED light to be reflected toward your eye while allowing all light from the other side to pass through, giving you your target. The angle of the front or objective lens ensures that you can see the red dot and it is parallax-free. Parallax-free means that it doesn’t change position depending on which eye you are looking at it with, or what position you are perceiving it from, it stays accurate. The glass is curved because as long as the LED(red dot) light is pointing at the focus or center of the curved mirror it will always appear to be in front of the viewer. If it is attached to the rifle and calibrated correctly, the red dot will appear at the point that the bullet will be going to. Since the LED reticle is projected onto the specially coated glass, it is kind of like a laser aiming device that only you can see. It is not reflected forward or towards anywhere but the viewing scope, that is, the place where you will be looking for target acquisition. 
     Anyone who has used a red dot scope can tell you how great they are to use when they are working properly. You aren’t lining up the front sight with the rear sight and then lining these up with the target or any of that. With these bad boys, you just look through the optic. If you see your target and the dot, then you are in business. Just put the dot on the target, squeeze the trigger, and have a nice day. It really is one of the most user-friendly targeting systems ever designed. 
     You would think that you would have to pay a lot for such a great system, and in the past, you would have. However as we have all observed throughout our lives, expensive things frequently become more affordable as people figure out better ways to produce them. If you’re just looking at the price you might think that someone just went and painted a red dot onto some round plastic and put them into a sleek black tube that has functional-looking dials on the side. That is NOT the case. The TacFire 1X30 Dual-Illuminated Red Dot Sight w/Cantilever Mount is a real red dot system that works how it is supposed to. How can you get a real, working red dot sighting system for that price? Well, TacFire has figured it out. 
     These red dot systems have been around for rifles since the 70’s and they have many advantages over iron sights, especially in the short to mid-range. Being able to use both eyes when you are looking through these sights is more natural and especially useful when you are in an intense situation. If you ever have to use your sights when your adrenaline is pumping, chances are your body has both eyes on deck, wide and taking in as much information as possible. Why fight that by forcing an eye closed(you really should keep both of them open when aiming anyway) and looking through a small opening with just the one eye? Why not instead use both eyes to put that red dot onto what is taking up all of your interest anyway? Then shoot it. 
     This is made with strong aluminum so as long as you treat it decently it should last for a while. Meant to last through any kind of recoil, this sight is cantilevered so that it comes up and forward from the rifle base where it is attached. Not only does this look cool but it makes it easier to attach it to the upper receiver, where you want it, and still allows you to use it properly. The amount of quality design decisions that have gone into this piece of hardware is considered all the more amazing given its low cost. As a bonus, you also get a green and blue dot. What?! Not just a red dot, but the option to make it a blue or a green dot? What high value! 
     This Red Dot Optic has no magnification, as is usual for this type. That’s part of why it’s so easy to use. What you see is what you get, just line up the dot and go for it. If you want to be set up to shoot long distances as well you may want to get a magnifier with it. We’ve combined both optics in one combo, to be used as one optics system. The magnifier flips up or away depending on whether you want magnification or not. Two great values combo’d into one great deal.
