I don't stay up to date with the latest procurement moves made by the special operations community, but it's news to me that 5.56 SCARs are being phased out by 2013. Sounds like they finally saw the light, that gas piston driven ARs or 5.56 rifles were looking for a problem that didn't exist with the traditional gas impingement systems - as long as the proper PMCS were followed. It doesn't sound like they are moving entirely away from 5.56 to 7.62 though, but for operations in A-stan, I'd would rather have 7.62, that being said though, a heavier grain bullet would be a nice stop gap measure, before phasing in 7.62 rifles if they indeed make the shift. I'd also imagine that the SEALs, Rangers, Army Special Forces, MARSOC, AFSOC or whatever tier 1 uber-death-ninjia-high-speed-low-drag group will still have some degree of freedom to choose their weapon systems based on what is most optimized for their particular mission, so there might be some SCAR-Ls out there when dust from the procurement battle settles.
