The Bergara B-14 HMR Rifle in .450 Bushmaster (Bergara part no. B14S356C) pairs Bergara’s hunting-and-match rifle design with a hard-hitting straight-walled cartridge built for big game. This HMR features an integrated mini-chassis molded directly into the stock for repeatable bedding and consistent accuracy, along with a fully free-floated 20-inch barrel finished in Graphite Black Cerakote. Built in Spain at Bergara’s own barrel factory, the B-14 action uses a smooth two-lug design with a sliding plate extractor for reliable feeding, and the threaded 5/8-24 muzzle ships with a thread protector. A 5-round AICS detachable magazine and an adjustable cheekpiece with length-of-pull spacers let hunters dial the rifle in for a precise, repeatable fit.
