GL15450SS TNG) is a semi-automatic AR-15 in .450 Bushmaster from Great Lakes, finished in Tungsten Grey and fitted with a muzzle brake and an 18-inch barrel. It carries a 1:24 twist, a five-round magazine and a mid-length gas system on a 7075 aluminum oversized upper. This listing is the Stainless edition in Tungsten Grey.
