This Huglu is 28" with 3 " chambers . 20 gauge. The bluing is like a protecting bluing. The stock is heavily coated. I think this is to protect the gun for use in rough weather. The gun is in great condition, at least 98% several very tiny marks on the stock. I have not fired this gun. I'm not a hunter. If you want to find out about it, go to: gunblast/huglu.htm.
