Others have had good luck with Vortex optics but I have had terrible luck with them and there are enough others on the form with the same experience to know there could a problem. It is kind of a hit and miss deal but if you aren't satisfied with the accuracy of your rifle it is possible the scope is defective. I agree about the muzzle brake, not needed and just more expense.

I think you will like your Axis. My Axis is either the most accurate rifle I have or as accurate as my much higher priced Model 12 22-250 heavy barrel.
