Ruger has recently announced the expansion of their popular AR-556 series of rifles with the new chamebering of 300 blackout.

The 300 Blackout has become a pretty standard cartridge in the AR-15 pattern.

It is only natural progression for Ruger to support the 300BLK cartridge in their AR-15 series.
