The 16.25-inch fluted barrel keeps it handy in thick cover, and the Flat Dark Earth synthetic stock shrugs off weather.

Key Features
- Spiral-Fluted Bolt — WHY IT MATTERS: Reduces friction and debris buildup, so cycling stays smooth even after a day in the dust or mud. The oversized bolt handle gives you positive purchase with gloved hands.
- LBA Adjustable Trigger — WHY IT MATTERS: Lets you dial pull weight from 2 to 7 pounds without a gunsmith. That means a crisp break for precision shots or a heavier pull for cold-weather hunting with thick gloves.
- 16.25-Inch Fluted Barrel — WHY IT MATTERS: Shorter barrel keeps the rifle maneuverable in brush and tree stands, while fluting sheds weight and helps cooling. The threaded muzzle accepts brakes or suppressors for recoil or noise reduction.
- Top Picatinny Rail — WHY IT MATTERS: No need to tap or drill — mount any standard optic right away. The rail is integral to the receiver, so zero holds secure even under heavy recoil from .450 Bushmaster.
- Detachable Box Magazine — WHY IT MATTERS: Reloads are fast and safe. Drop the mag, pop in a fresh one, and get back on target. The 4-round capacity keeps you legal in most straight-wall states.
Who It’s For
This rifle is built for the hunter who chases hogs in thick Texas brush, stalks whitetails in Michigan’s straight-wall zones, or needs a truck gun that can handle bear country. It’s also a solid pick for the first-time centerfire buyer who wants a hard-hitting, easy-to-maintain bolt gun without the premium price tag. If you value compact length, reliable feeding, and a trigger you can tune yourself, the Patriot in .450 Bushmaster fits the bill.
Pros & Cons
- Pro: Lightweight at 6.75 lbs — easy to carry all day.
- Pro: Threaded barrel with factory-installed rail — ready for optics and suppressors out of the box.
- Pro: LBA trigger is user-adjustable with no tools needed.
- Con: Factory trigger can feel a bit gritty out of the box — a few cycles or a light polish smooths it up nicely.
- Con: The synthetic stock has a hollow feel — not as rigid as a laminate or chassis, but it keeps weight down and cost low.

FAQ
What is the barrel twist rate on the Mossberg Patriot 450 Bushmaster?
The barrel has a 1:24-inch twist rate, which is standard for .450 Bushmaster. This twist stabilizes the heavy 250-300 grain projectiles commonly used in this caliber for hunting large game.
Does the Mossberg Patriot 450 Bushmaster come with a scope?
No, the rifle is sold without optics. However, it includes a factory-installed Picatinny rail on top of the receiver, so you can mount your choice of scope or red dot right away. Many shooters pair it with a 1-4x or 2-7x scope for brush hunting.
Is the Mossberg Patriot 450 Bushmaster legal for deer hunting in straight-wall cartridge states?
Yes. The .450 Bushmaster is a straight-wall cartridge, and the Patriot model meets the barrel length and magazine capacity requirements in most states with straight-wall restrictions (like Ohio, Michigan, Indiana, and others). Always check your local regulations before hunting.
Can I mount a suppressor on the Mossberg Patriot 450 Bushmaster?
Yes. The barrel is threaded 5/8×24 TPI, which is a common suppressor thread pitch. A suppressor helps reduce the sharp report of the .450 Bushmaster, making it more pleasant to shoot and less likely to spook game at close range.
What is the magazine capacity of the Mossberg Patriot 450 Bushmaster?
It comes with one detachable box magazine that holds 4 rounds. Extra magazines are available from Mossberg and aftermarket sources. The 4-round capacity is typical for hunting rifles and keeps you legal in most jurisdictions.
