When I purchased it , the Gun was a off brown rust color..
I took it home and soaked it in "the good stuff" for about a day and a half and then cleaned it...If you don't keep a nice coating of Outers oil on it..it starts to turn colors again.
Advanced has a Tacticool setup for it w/ mounts for lasers etc..
I could see this as a great breech weapon, you wouldn't have to blow the hinges off the door with this gun..all you have to do is stand back 20 ft. and with a load of .00 Buck you can make a man size hole in the door.
They say the .10 is 3x as powerful as the .12 I think its more like 5x
I'm a big guy 6'1" and 235# and that "boom stick" is the most powerful firearm I have shot..I shot a Casull once and thought I was going to break my wrist..
