I'm am listing this again because the first deal fell through....
I have a Burris Fast Fire II I am selling. I bought this sight new and have used it on my 835 for 2 years. This sight is in excellent condition with all original packaging. I recently sold the gun it was on and am selling this to help pay for my new gun. I had it mounted on a Marlin 336 mount but also have the rail mount that the sight came with. The 336 mount fits great on a 835/935 and is pictured below. I have to have $150 for the sight and mount.
