Silver Shadow has officially unveiled the double barreled AR-15 I blogged about last month. The Gilboa Snake has two barrels that are fired simultaneously, essentially double tapping on a single trigger pull. It will be available in both semi-automatic (two rounds per trigger pull) or full auto. The rifle, with its two 9.5″ barrels, weighs 9.4 lbs.
