I took some photos:






I looks worse then the photos show. And you can definitely see the bulge from inside the barrel. Not sure if you can see the bulge, but the bulge runs a little over an inch long. Very pronounced!

I went to the Green Mountain website and they didn't have my barrel. They did have a .50 cal barrel in carbine length (21"). I did write them an email and will see what they say. That .50 barrel was only $149.95. A great price, but I have a .50 cal barrel already.
