The gun you smoke before it smokes you.
Yes, this is a 34" long x 16" high x 7" deep, borosilicate glass pipe made to look like a AR-15. The bowl itself is located atop the ACOG scope, the pistol grip is the water reserve and seemingly smoked from the end of the barrel. It was crafted by mickelsen studios and if you read on you can see it in full awesome detail.
Puff, puff *blast*
