Specifications are incorrect - TRYBE Defense Medium Profile AR-15 Barrel, 5.56x45mm NATO

Please see other reviewers questioning accuracy of description of product. Specifications said this had a mid-length gas system with a .081" gas port. and he model I received takes a carbine gas tube and the gas port is substantially smaller than .081. It looks like they have since changed the description to say carbine length gas system but haven't changed the specifications. The barrel they sent me definitely has a carbine length gas system. Given the importance of the barrel, kind of concerns me what else they got wrong. Hope they got the 5.56 part correct. I wouldn't buy again from this brand.
