ADCO Solo Sight System multi Reticles Red Green
This item was first brought our for open class Steel Challenge style shooting and Bowling Pin shooters too, but soon thereafter the 3 gun match guys started putting the SOLO on AR15 platforms. With have is 3 MOA dot, a 10 MOA dot, a bracketed dot and a T-dot to present that can be changed at any time without need to rezero was a great aid to them. Sometime target size varies too, so having varied dots to pick from makes it nice; and to top it off you can change the presentation from red to green in varied brightnesses. This is unique!
