Description
The Mossberg Patriot .450 Bushmaster 18″ Threaded Bull Barrel is a compact bolt-action rifle built for serious defensive and hunting use. Chambered in .450 Bushmaster, it delivers heavy-hitting terminal performance while the 18-inch bull barrel keeps the overall length short for tight quarters. The factory-threaded barrel accepts muzzle devices or suppressors, and the Picatinny rail makes optics mounting straightforward. This is a no-nonsense tool for shooters who need a reliable, hard-hitting rifle that handles brush and close terrain without compromise.

Key Features
- 18″ Threaded Bull Barrel – Why it matters: The shorter, heavier barrel improves stability and accuracy while keeping the rifle compact enough for home defense or hunting in dense cover. The factory threading (standard 5/8×24) lets you attach a suppressor or muzzle brake without a gunsmith.
- Spiral-Fluted Bolt with Oversized Handle – Why it matters: The fluting reduces weight and adds a touch of style, but the oversized handle gives you a positive grip for fast cycling under stress—critical when you need a follow-up shot on a threat or game.
- Adjustable LBA (Lightning Bolt Action) Trigger – Why it matters: Mossberg’s user-adjustable trigger lets you dial in pull weight from 2 to 7 pounds. A crisp, clean break means better accuracy and less flinch, especially important with the .450 Bushmaster’s recoil.
- Top-Mounted Picatinny Rail – Why it matters: No need to buy separate bases. The integrated rail accepts any standard scope rings, so you can mount a red dot or low-power variable optic quickly for close-range defensive use.
- Compact Fixed Synthetic Stock – Why it matters: The 12.5-inch length of pull and slim forend make the rifle easy to shoulder and maneuver in tight spaces, like a vehicle or hallway. The synthetic material resists moisture and dings in the field.
Who It’s For
This rifle is built for the concealed carrier or home defender who wants a primary or backup long gun that can stop threats with authority. It’s also ideal for hunters who need a short, handy brush gun for black bear, wild boar, or deer at close range. The .450 Bushmaster round delivers massive energy transfer, making it a top choice for those who value stopping power over magazine capacity.
Pros & Cons
- Pros: Hard-hitting .450 Bushmaster caliber; compact 18-inch barrel for tight spaces; factory-threaded barrel for suppressors; adjustable trigger; affordable price point under $450.

FAQ
What thread pattern is the barrel?
The barrel is factory-threaded, typically with a 5/8×24 pattern to accept standard .45-caliber muzzle devices and suppressors. Verify the exact spec on your specific barrel as variations may exist per production run.
Can I mount a red dot sight on this rifle?
Yes. The top Picatinny rail accepts any standard scope rings or direct-mount red dot optics. For close-range defensive use, a low-profile red dot like a Holosun or Aimpoint works well with the compact layout.
Is this rifle legal for hunting in all states?
.450 Bushmaster is legal for deer and big game in most states that allow straight-wall cartridges, including Michigan, Ohio, Indiana, and others. Check your local regulations as some states have specific restrictions on magazine capacity or barrel length.
Does the rifle come with a scope?
No, the Mossberg Patriot .450 Bushmaster is sold as a rifle only. The Picatinny rail is included, but you’ll need to purchase optics separately.
What is the magazine capacity?
The rifle uses a detachable box magazine with a standard capacity of 4 rounds. This keeps the profile low and complies with hunting regulations in many states.
This Mossberg Patriot .450 Bushmaster 18″ Threaded Bull Barrel delivers hard-hitting performance in a compact package. Whether you need a defensive rifle for home protection or a brush gun for hunting, it offers reliable function and solid accuracy at a price that won’t break the bank.
