Ultradot without hesitation. They carry a lifetime warranty and are reliable as the day is long.

I agree on the above but I have a Burris Speed dot on my .454 and its a winner also.I have been thru two from the recoil and settled on the Burris.It has held up for about 150 heavy rounds so far but I just found out that there illegal to hunt with in Idaho????Bummer now what do I do?Back to open sites or trade it for a traditional scope like a Leupold.If you get one be sure to carry extra batteries.

Best of luck.Jayco.
