Got This shotgun a few months ago. Has an 18" barrel and came spray painted grey. I sand blasted it and dipped it in our Bluing tank.. Came out great. I took the receiver to the bater and smoothed it out.., got rid of unwanted edges. The stock was sanded.. Primed.. Sanded and sprayed black. I plan to do this to a few more single shot 12's I have laying around. Bluing was done by Blue Ridge Bluing.
