Very nice! When you say 336 mount, I assume that's a Marlin 336 mount?
Yeah, if you look at the Burris FF's they show a mount called a 336 which fits a Marlin. It takes 8-40 screws.
Thanks for that info! I'm thinking I may want to red dot my 20ga and may go this route. Other option is to just use a regular 870 base and something like a TRS-25.
