.30 Rem. AR: Magazines and Muzzle Velocity

I've had a couple questions come to me about the magazines for the platform. The mags are going to be single stack mags with a four round capacity.

Another thing: The info in the ballistic chart was generated with a 24-inch barrel, the folks at Remington told me. Given that the R-15 in .30 RAR will have a 22-inch barrel I would expect to see the actual muzzle velocities to graf around 75 fps less than the data I gave in that original chart, which would put it around 2,725 fps.
