Mossberg Patriot Predator Rifle .450 Bushmaster 4rd Magazine 20" Threaded Barrel FDE
The Mossberg Patriot Predator rifle in .450 Bushmaster is a hard-hitting bolt-action built for serious predator and medium-game hunting. This 20-inch threaded-barrel rifle arrives suppressor-ready, letting you thread on a can for hearing protection and noise reduction in the field—a practical advantage whether you're hunting coyotes at first light or managing nuisance predators on your property. The FDE synthetic stock gives it a clean, modern look that works in brush and open country alike.
What sets the Predator apart is the Patriot platform itself: a proven, dependable chassis that's earned respect across the hunting and sport-shooting community. The fluted barrel sheds heat and weight without sacrificing rigidity, while the 11-degree match crown promotes accuracy shot after shot. A user-adjustable LBA trigger lets you dial in the pull weight between 2 and 7 pounds—tighter for precision work, lighter if you prefer—and the oversized bolt handle cycles smoothly even in cold weather or when wearing gloves. The top-mounted Picatinny rail accepts any standard scope or optic, so you can set it up exactly how you hunt.
The .450 Bushmaster cartridge delivers serious energy in a short-action package, making it a go-to round for hunters who want stopping power without the length and recoil of a .308 or magnum. With a 4-round capacity and 1:24 twist rate optimized for modern .450 ammunition, the Patriot Predator is ready for the field or the range. At 6.5 pounds, it's handy enough to carry all day yet solid enough to shoot tight groups from a rest.
