Hey just want to let everyone know how these scope covers work on my Lucid red dot. I bought the Butler creek 23 OBJ for the front and the 05 OBJ for the back. They fit pretty snug and work great. You will have to take the front cover off to access the battery compartment. But I'm happy with the set up. Just wished the covers were clear plastic, but it takes no time to flip up the covers.
