I have a Bushnell with the 4 reticles an my AR and like it very much. One of my 22s has the large BSA and it works well and is very inexpensive.
I wanted a Bushnell holosight but did not have the $$ so at a gunshow in Orlando, I bought a Aimshot holo from the company rep. What a POS. It quit after the first shot and their customer service is the worst I have dealt with. They just jerk you around.
I have some of the Tasco red dots also, they are OK but the Bushnell has much sharper dots than the Tasco or BSA.
