I have Burris FFII 3-9 Scopes, and I have a Bushnell Banner Scope in 4-16.
Also have Bushnell Scopes in the AR Class with the 1-4(BDC) and a TRS32 Model. The AR Scope Glass is better than the Banner line.
Bushnell Glass, even on the cheaper Models has come a long ways as compared with a 80/90's Bushnell. I would Say that the Glass gets much better with the Trophy and up Models---which include the AR Models, but whether Bushnell uses the Trophy or Elite Polished/Coatings type Glass, I don't know.
You would need to move up to the discontinued Elite 3200 in the Bushnell lineup to get the quality of Glass that Burris has in the FullfieldII Lineup.
If you're looking for a Scope that would compare with the Burris FFII, I would look at a Redfield Revolution. These Scopes don't have A/O, but the Glass is superb and Scope is rugged. Parallaxed at 100yds.
Redfield has come out with a new lineup called Revelation that have A/O on the higher magnification models, at less cost than Revolution, but I hear they're made in China---but with better QC.
