I have the "bug buster" and I've been really surprised at how good it is. There are always people that are the "its not an ACOG so its garbage" that review things but for the $$ this optic is really clear and holds 0 on my AR. If you are looking to use it at the range for fun, its a great optic. I have about 1000 rounds with it now and I really have nothing bad to say about it besides the adjustment clicks could be more precise. Definintely much better than I was expecting.
