This optic is by far the best red dot I have ever had. For the price that it is at, you cant beat it. Adjusting the sight is very easy! They state that it is weather proof, and I can testify to that. Used it in a competition where it started to rain for about 2 hours straight, and this guy never messed up. Yes, the front lens is red. The lens covers aren't as sturdy as I though they would be though, they fall off when I run. All metal I believe.
IF YOUR WEAPON HAS A RAIL SYSTEM ON, IT WILL FIT
If you need a simple red dot that gets the job done, this is your guy.
All metal (I think)
Locks on great
Lens cover fall off easily
Enemy can see red dot even on lowest setting at night
