$50 for a red dot sight is alot but I can garente you it is all worth it. The aimpoint style looks very cool on your gun and gives you a clear view of your target while remaining quite small. you may choose red or green dots each with 5 levels of eye relief, perfect for any short to medium range. This sight offers no magnification withch could hurt you in long range fights, therefore i would advise ataching it to a SMG, carbine, or short barreld assult rifle. The riser mount is a great extra witch allows you to see over your iron sights. It is a compct sight witch you can calibrate effortlessly, just make sure you follow the instructions. This red/green dot sight includes a battery.
