How does the mercury recoil reducer on the Benelli Supernova shotgun work? Update Cancel. Quora User, former MTS Support at Silicon Graphics (1989-2002) Answered Oct 21, 2018 Author has 1.2k answers and 587.7k answer views.
I've had a non-tactical Nova for a few years. It's a nice shotgun. Well made and pretty smooth. I like the mag cutoff button deal that allows you to cycle the action without advancing the next shell from the tube. I ended up installing the mercury recoil reducer in the stock. It was a little spendy, but works pretty well in toning down the beating. My only real complaint is that every time I wipe the exterior of the barrel with an oiled patch, it comes off rusty brown.
I suspect it'd wouldn't take much weather exposure for it to go into full fuzzy-red-rust-bomb mode. It's regularly maintained and lives in a climate-controlled safe, so I'm pretty sure it's the finish and not how it's treated. Could just be something wrong with mine, though. Anyway, they're good guns and should serve you well.
