Im looking for some decent lightweight optics that will work for deer size hunting with an AR 70g .223. Im leaning to leupold ultralight or perhaps burris timberline fullfield - its a .223 - for use at modest ranges, say 200 yards or so max:

pretty much set on ome of the following –– thoughts? Ive been pretty happy with my other burris, although the leupold is a bit lighter in physical weight.

Not trying to plug anything, but of these which might be best for an AR

thoughts?

The FFIIs are nice scopes and the BDC works well for an AR.  I have a Timberline and a FFII and I would suggest the FFII in 2-7x35 for an AR platform.

What is a utilitarian use of a scope?

I had a Burris FFII 3-9x40 and it was pretty nice on my AR out to 300yds esp for only $190. The BDC was great with Fed 55gr.
