I have one of these myself. I have shot 2 matches with it mounted on my ar9 thus far. It is clear and holds zero well. No issues so far. what i really like is that it uses aaa batteries.
I shot my 1st 3 gun this past weekend in Gonzales. It was a blast and I am looking forward to the next one for sure.
Like someone else mentioned, I started by shooting pistol matches 1st then worked into the 3 gun.
If it was replaced with one that said you can't carry then there would be a problem. It is my understanding that you are not allowed to carry according to the louisiana laws is when a no gun sign is posted.
