The Mossberg Patriot Synthetic Scoped Rifle in .450 Bushmaster is a no-nonsense, ready-to-hunt package built for hunters who want serious cartridge performance without the assembly hassle. This 20-inch barreled rifle ships with a 3-9x40mm scope already mounted on Weaver-style bases, so you can glass a field or dial in at the range straight out of the box. The .450 Bushmaster cartridge punches hard at moderate distances—a smart choice for whitetail and hog hunting where brush and timber demand a heavy, straight-shooting round.
Mossberg engineered the Patriot platform for reliability and accuracy without excess weight or complexity. The synthetic stock handles weather and rough handling with zero fuss, the matte blue barrel finish resists corrosion, and the spiral-fluted bolt keeps things running smooth. You get an adjustable trigger (LBA) so you can dial in break weight to your preference, plus a threaded muzzle (11/16-24 TPI) if you ever want to add a brake or suppressor. The 4+1 magazine capacity is standard for the platform and keeps you armed and ready in the field.
At 6.5 pounds and 40.25 inches overall with a 13.75-inch length of pull, this rifle balances pointability with stability. Whether you're a first-time .450 Bushmaster shooter or a seasoned brush hunter upgrading, the Mossberg Patriot gives you factory accuracy and field-proven cartridge ballistics in a package that doesn't require guesswork or extra purchases.
