NEVER spend more than 50% of the purchase price of your rifle on optics! NEVER! That is, unless you have a job that requires you to run to gunfire, or attack on-command. Become very proficient in the use of iron sites, then add reflexive optics (red dot-type), and them add magnification. If you can have a single optic that provides reflexive target acquisition as well as magnification (fixed 3X - 5X), you should consider buying. Consider all features before making a final decision. http://www.burrisoptics.com/sights/ar-sights-series/ar-332
