Battle Arms Development just launched their new site. The clean, easy to navigate design is great but what you really need to check out is all the new goodies they loaded on the new site. The new BAD556-LW receivers are there with more specs that were released previously (though the weight is still not available). There is also a very good looking new AR-15 barrel with a proprietary contour and fluting pattern.
