bnbrk94, yes I have compared both and now were splitting hairs. The biggest difference is the eye relief, the SII is less critical and very friendly. The glass on the SII is a bit sharper and crisper. The weight, length and mounting space are almost identical. In this post or a previous post I noted that I had 2 3-9X42's with different eye relief. One was terrible and one was awesome. They were only about 2 years different in manufacture time. The new ones have awesome eye relief, the old ones are bad.
The only knock on the FFII's is customer service. I have not had the greatest luck with Burris customer service. Sightron's customer service has been outstanding. The older SII I have will go back and I'm sure I will receive a new one in a week.
Hope this helps, any other questions please ask.
Rob
