Although the 10/22 is super customizable I would have to say don't get it because it is expensive to do so. I would go with a bolt Savage, very accurate especially for the price. Are you set on the WMR? .22 LR is about 3.5x cheaper to shoot which should be a consideration.
I'm gonna stop you right there, you just said an AR-15 is a high-powered rifle. It is obvious you don't know anything about guns and I shall ignore anything you say from this point on.
