Ever want a P90 but dont want to spend the 1-1.2k on one? Have an AR already? This may be for you. Coming out this year is an AR upper for 5.7x28mm that takes p90 mags and is top feed.
Ben said:I thought the only benefits of 5.7 over 5.56 was it's smaller size and less recoil for use in pistols and submachine guns. Plus it's rare and expensive, so why would you do this other than the wow factor of having something different?
Definately Not better than 5.56 and I am starting to think maybe not even better than 9mm.Ben said:How do you figure 5.7x28mm is better than 5.56, or are you talking about the 9mm AR's?
