Here's the problem with this concept. We all know the AK series to be extremely reliable- which they are. They are also not very accurate- as the series has developed, this has been addressed, but it is still not as accurate as most Western battle rifles, like, say, an L1A1 or a M16A2. The reason for this reliability is the tolerances; the AK has extremely loose tolerances. This means that it is very reliable- and inaccurate. You see, the M16 has relativley tight tolerances- this makes it far more accurate (you can take a lot of headshots from long distances, if you're competent- there was an investigation into this at Falluja, because the number of headshots was very high, and they thought the marines were executing people.) Therefore, for the SIR to have AK-like reliability and M16 (or maybe even M14?) like accuracy, is...difficult to perceive. I could obviously be wrong, because my knowledge in this field as not as high as I'd like it to be, but from my understanding of things, it is hard to have a very accurate and supremely reliable gun that is not relatively simple.
