I like the fact that it's a bit more put together than the green dot sight that you get with other gel blasters or foam blasters. It's also a bit easier to use than a foam blaster.
This is not even good for a bb gun. There are fake * that don't adjust anything. A green cross appears on screen, but can only be seen indoors. Another downside is that the mounting process is easy.
The green dot is larger in diameter than i was expecting and the brightest dot i could imagine. It takes 3 shots to put you on the bullseye.
