I agree with the 4200. Save your $$ and go with the 4200 4-16x50mm. I have two of the old side focus versions and they are super clear and plenty of power for the ranges I shoot at. I also have a few of the pentax pioneer original model 4.5-14x42 scopes, from what I hear they are very similar to the burris fullfield II line. They have been pretty excellent on clarity etc. The reticle is a little fine for right at dark, but its a nice built scope for what I paid for them. The fit is super tight on them as well.
