Big Boy rifles in “revolver” calibers established the original reputation of our centerfire models. These All-Weather versions let you hunt in the rain and the snow with no fear of creeping rust. We have further upgraded these rifles to include a side loading gate for rapid magazine top-off while retaining our original removable tube magazine for safer unloading. These slick, tough rifles come in three calibers, all with 20-inch round barrels for the long sight radius and maximum ballistic performance.
