Update after use - Bushnell AR Optics Rifle Scope 3-12x40mm

This is an update on this scope, have noticed that at lower zoom around 8-10 performs much better as far as edge distortion and critical eye placement in center. Makes me wonder why not just stop at 3-9 instead of trying to use 3-12 without upgrading internals to meet the 3-12 requirements to use at full potential.
Would also like to add the great price and fast shipping on everything I have purchased at Optics Planet, great customer service , Thanks!
