They're about the same. Not quite there on quality.
In my experience, a lower powered, yet clearer scope, will be much better than a higher mag, lower quality.
If you need a budget minded scope, in a higher mag, with good optics...I would highly recommend the Mueller APT 4.5-14x44 at JoeBobOutfitters.com. Joseph, the owner, runs on on his personal AR-15 with great results. I have a Muller APV on my Savage HMR and love it. Either one is suitable for center fire use.
The APT is $169 plus 5% off
The APV is $129 plus 5% off
