Any scope without an AO is set for a specific distance, usually 100yds in the case of a centerfire one. Because of this when used at any distance other than the one set it will have paralax. How much is not rreevealed by your post nor is how you determied it so its hard to say if the amount you are seeing is excessive.
I'd suggest checking for paralax at 1oo yds, if there is some you have a problem if not then it's normal. To remove paralax at multiple distances you'd need to get one with an adjustable objective & adjust for each distance.
