Everybody’s favorite humpback shotgun and all the duplicate models are featured in this two-hour long video course. Using a cutaway action and artists drawings, Master Gunsmith Bob Dunlap explains all the intricate details of this recoiling action. Finally, everyone who has ever owned one of these popular guns can understand the design and function of John Browning’s best-selling shotgun.
