Probably slow down your MV by up to 200fps maybe.
now heres the funny part, I checked this morning with a friend of mine that can order guns, he said that the marlin with the 20" barrel is $8 cheaper than the 18" but the one with the 20" barrel does not have the "G" behind the 1895 so I guess its not a guide gun??? I dont think you can get a guide gun with a 20" barrel. And yes 200 fps is about what I was thinking on the extra 2" Big boy
