Mossberg 28259 Patriot Full 20" 5-Round Threaded Barrel Rifle

The Mossberg 28259 Patriot Full Size 450 Bushmaster is purpose-built for hunters and shooters seeking a modern, suppressor-ready rifle chambered in one of the most effective straight-wall hunting cartridges available. Built on Mossberg's proven Patriot chassis, this rifle delivers the accuracy and reliability demanded by serious hunters and tactical shooters who operate in dense cover or require subsonic ammunition capability. The 450 Bushmaster cartridge offers superior stopping power at close to mid-range distances while remaining legal in many straight-wall-only hunting jurisdictions.

This rifle features a 20-inch stainless steel barrel with 11-degree Match Crown and threaded muzzle, engineered for suppressor compatibility and precision shot placement. The fluted design reduces weight while maintaining structural integrity, and the stainless Cerakote finish provides corrosion resistance in harsh field conditions. An optics-ready Picatinny rail is factory-drilled and tapped into the stainless Cerakote receiver, enabling rapid mounting of tactical scopes or red dots without gunsmithing. The spiral fluted bolt cycles smoothly under pressure, while Mossberg's patented LBA user-adjustable trigger allows customization of pull weight and break characteristics to match individual shooting preferences. An oversized bolt handle ensures reliable operation while wearing gloves, and the black fixed synthetic stock provides a lightweight platform weighing just 8.6 lbs.

This configuration serves hunters transitioning from AR platforms to bolt-action precision, operators running suppressed setups, and shooters in regions requiring straight-wall cartridges for big game. The 450 Bushmaster's 4+1 capacity (four rounds in magazine plus one chambered) meets hunting regulations across most jurisdictions while maintaining quick follow-up shot capability. The threaded barrel accepts industry-standard suppressors with appropriate thread pitch (11/16x24 TPI for 450 Bushmaster), allowing subsonic rounds to reach velocity thresholds when sound signature reduction is critical. Installation of optics requires only standard Picatinny-compatible rings and mounts—no additional modifications necessary.
