From what I have seen, with equal barrel and ammunition quality between rifles, I would NOT put money against an AR-based semi-auto against any other semi. If we get into Highpower match rifles, being fired from position, by shooters of the same classification, retaining the equal barrel and ammunition, I wouldn't necessarily bet on a bolt-action outscoring an AR 100% of the time. One of my acquitances from Highpower shoots an AR-15 based .223 space rifle, and watching him shoot is downright eery. (Yes, he is a High Master.)
BTW, nice H&K. Enjoy.
