Bergara B-14 HMR 450 Bushmaster 20" 5R Barrel Bolt-Action Rifle - Black/Brown

The Bergara B-14 HMR 450 Bushmaster bolt-action rifle combines Spanish manufacturing precision with a modern platform built for both hunters and long-range shooters. This 20-inch 5R-barreled rifle in 450 Bushmaster arrives factory-ready with the kind of fit and finish you'd expect from a custom gun shop—but at production-rifle pricing. Bergara's reputation in the custom rifle world carries over here: you're getting a two-lug action with a super-smooth bolt cycle, a world-class barrel with a Graphite Black Cerakote finish, and a stock architecture designed around repeatable accuracy from day one.

The B-14 HMR's integrated mini-chassis molded into the stock ensures bedding consistency across shots, while the fully free-floated barrel eliminates contact with the forend—a precision-rifle hallmark. The Bergara-curved trigger is factory-set at about three pounds and breaks crisp, no takeup. You're getting Remington 700 pattern drilling and tapping (6-48 screws), so scope mounting is straightforward with any standard base. The 5/8-24 threaded muzzle comes with a protector and is ready for brakes or suppressors if you go that route.

The stock features an adjustable cheekpiece and length-of-pull spacers so you can dial in a natural sight picture and comfortable length of draw. Quick-detach flush cups are molded in for sling attachment. A 5-round AICS-pattern detachable magazine ships standard. At 9.5 to 9.9 pounds and 40 inches overall, this rifle balances portability with the rigidity needed for reliable precision. Whether you're hunting brush country with 450 Bushmaster's short-range authority or working a rifle range, the B-14 HMR delivers repeatable performance without the custom-shop wait.
