Has anyone here recently done, from a defined and reasonable distance, a valid bench rest rifle to rifle shooting comparison of the accuracy of the standard M&P 15-22 and the Performance Center M&P 15-22 rifles? I’ve read several, but not all, forum posts about some differences in the comparative limitations and accuracy of the two rifles; but, the expressions in the posts, from shooters or not, tend to be opinions. Has anyone done recent definitive testing comparing the two rifles?
