Mossberg Patriot .450 Bushmaster 20 in. Synthetic Black RH
About this product
The Mossberg Patriot .450 Bushmaster is a bolt-action hunting rifle built for short-range, high-impact deer and hog hunting in thick brush where straight-walled cartridges are legally required. It combines Mossberg's proven LBA trigger system with a 20-inch fluted barrel and synthetic stock for all-weather reliability at a price point that undercuts most competitors. Chambered specifically for the .450 Bushmaster round, this configuration delivers over 2,600 ft-lbs of muzzle energy with proper ammunition while maintaining a compact 41.5-inch overall length that won't snag in blind windows or dense cover.
What is the Mossberg Patriot .450 Bushmaster used for?
This rifle is purpose-built for hunting medium to large game in states requiring straight-walled cartridges, delivering lethal energy within 250 yards. The .450 Bushmaster cartridge produces approximately 2,600 ft-lbs of muzzle energy with 250-grain bullets, making it ideal for whitetail deer and feral hogs in thick cover where shot distances rarely exceed 150 yards. Its threaded muzzle accepts suppressors or muzzle brakes, though hunters should verify local regulations before adding either accessory.
How does the Mossberg Patriot compare to the Stevens 334?
The Patriot outperforms the Stevens 334 in cartridge energy and specialized hunting applications, though the Stevens offers better long-range versatility. Where the Patriot's .450 Bushmaster delivers massive impact within 250 yards, the Stevens 334 in .308 Win maintains higher velocity and flatter trajectory beyond 300 yards. For hunters in straight-wall-only states or targeting heavy-bodied game at close range, the Patriot's 2,600 ft-lbs energy advantage makes it the better choice despite the Stevens' superior accuracy at extended distances.
What does it weigh and what are the dimensions?
This rifle weighs 7.5 pounds unloaded and measures 41.5 inches in overall length with a 20-inch barrel. The synthetic stock contributes to its relatively light carry weight compared to walnut alternatives, while the 13.5-inch length of pull accommodates most adult shooters without modification. With optics mounted, expect total weight to approach 8.5-9 pounds depending on scope selection and ring configuration.
Who is this NOT for?
This rifle isn't suitable for long-range precision shooting or hunters in states without straight-walled cartridge restrictions. The .450 Bushmaster cartridge drops approximately 18 inches at 300 yards, making it ineffective beyond 250 yards compared to flatter-shooting rounds like the .308 Win found in the Stevens 334. Target shooters wanting sub-MOA accuracy should look to heavier-barreled varmint rifles rather than this field-oriented hunting platform.
What's in the box?
Each rifle ships with one 4-round detachable box magazine and Weaver-style scope bases pre-installed. Mossberg includes basic safety literature and a cable lock, though serious hunters will immediately upgrade to a quality scope mounting system rather than relying on the included bases for heavy-recoil applications. No tools or additional accessories are provided for trigger adjustment or maintenance.
Is the Mossberg Patriot worth it at $417.99?
At $417.99, this rifle delivers exceptional value for hunters needing straight-walled cartridge compliance without sacrificing reliability. Compared to custom-built alternatives costing over $800, the Patriot provides 90% of the performance for 50% of the price, though buyers should budget another $200-400 for optics capable of handling the .450 Bushmaster's substantial recoil. For the price, you're getting a mechanically sound hunting tool that won't fail when needed most.

Frequently asked questions
- Is the barrel thread compatible with .458 SOCOM suppressors?
- Yes, the 11/16"x24 TPI threading matches most .458 SOCOM muzzle devices and suppressors. However, always verify suppressor manufacturer specifications—some .45-caliber cans require specific thread adapters or mounting systems beyond direct thread.
- Does it come with open sights or require optics?
- No open sights are included—this model requires optics mounted to the pre-installed Weaver bases. Plan on spending $150-300 for a quality low-power variable optic (LPVO) capable of handling the .450 Bushmaster's recoil impulse.
- How long does shipping take to FFL dealers?
- Most orders ship within 3 business days via FedEx or UPS, with transit times of 2-5 days depending on destination. Your chosen FFL dealer must provide their license before shipment can processing—allow 7-10 total days for delivery.
- Can I use .45-70 Government ammunition in this rifle?
- Absolutely not—.45-70 Government generates nearly double the pressure of .450 Bushmaster and will cause catastrophic failure. Only use SAAMI-spec .450 Bushmaster ammunition with maximum pressure of 38,500 psi.
