Excellent sight for the money - Vortex Crossfire Red Dot Sight

This is an excellent red dot. For the price point you really can't beat it. Some may complain that you can't go from off to the brightest setting, but I am on the other side of the argument. I like being able to know where I am at with the brightness setting without actually having to look at the optic, especially when turning it off. The dot is plenty bright, clear, and holds zero perfectly fine after bumping it around and throwing a couple hundred rounds through it. I have this mounted on a 7.5" 300 blackout pistol with a flash can, and it has stayed true, and MBUS backups work perfect through this optic. You also do not need a tool to zero it in, as the caps have the tool built right into the top of them. You really can't beat it for the money.
