The over-and-under is the classic Merkel hunting gun. The B3 is specially designed for the driven hunt and the rapid second shot. The features include double locks, manual cocking system, and adjustable single trigger. Merkel has brought the practical features of this MEM development up to the technically highest level. The technology is combined with the high-strength Suhl tilted block breech. The slim barrel set is constructed without an upper tube, which saves on weight; the lower barrel is free floating. The muzzle adjustment is protected by the forearm. The lines of this over-and-under rifle follow the Suhl tradition: from the Schnabel on the forearm to the curved side of the stock.
