Category:

The Mossberg Patriot in .450 Bushmaster is a bolt-action rifle built for American hunters and shooters who need reliable, hard-hitting performance in the field or at the range. Designed to take down medium to large game at moderate distances, this model combines a 20-inch barrel with a Moss Green finish for a practical, no-nonsense tool that handles well in varied conditions. Whether you’re tracking whitetail in dense woods or punching paper at the range, this rifle offers a straightforward, dependable platform.

What This Product Is and Who It Is For

The Mossberg Patriot is a bolt-action rifle chambered in .450 Bushmaster, a straight-wall cartridge known for its substantial energy delivery at close to medium ranges. This specific configuration is intended for hunters who require a legal, powerful option in states with straight-wall cartridge restrictions for deer and similar game. It also appeals to target shooters who want a robust, manageable caliber for recreational shooting without the sharp recoil of larger magnums. The Moss Green finish provides a subdued appearance suitable for outdoor use, making it a practical choice for those who prioritize function over flash. This rifle is not designed for concealed carry or home defense; its length and bolt-action mechanism are optimized for stationary or stalking hunting scenarios and range work.

Feature Deep-Dive

The Mossberg Patriot’s barrel is cold hammer-forged and fluted, which contributes to consistent accuracy while reducing overall weight. The 20-inch length is a practical compromise between maneuverability in brush and maintaining sufficient velocity for the .450 Bushmaster cartridge. The fluting also aids in cooling during extended shooting sessions, helping to maintain barrel integrity over repeated shots. This attention to barrel construction is a key reason why the Patriot series has earned a reputation for out-of-the-box accuracy at its price point.

The adjustable Lightning Bolt Trigger is a standout feature for shooters who want to fine-tune their pull weight. With a user-adjustable range from 2 to 7 pounds, you can set the trigger to match your preference without needing a gunsmith. The trigger design is crisp and breaks cleanly, which is particularly beneficial when working with the .450 Bushmaster’s recoil impulse. A consistent trigger pull reduces the likelihood of flinching and improves shot placement, whether you’re taking a 100-yard shot at a deer or zeroing at the range.

The synthetic stock is reinforced with an aluminum pillar bedding system, which helps maintain a stable action-to-stock interface for consistent accuracy. The raised cheek comb is designed to align your eye with a mounted scope, a practical touch for shooters who prefer optics. Textured grip panels on the forend and pistol grip provide a secure hold in wet or gloved conditions, and the stock’s Moss Green color offers a low-visibility profile that blends well with wooded environments. The stock also includes sling swivel studs for easy attachment of a carrying sling.

The detachable box magazine is a notable convenience feature, allowing for quick reloads and safe unloading without cycling rounds through the action. The magazine is constructed from polymer with a steel feed lip insert, balancing durability with lightweight handling. It fits flush with the stock, reducing snag potential when moving through cover. The magazine release is located at the front of the trigger guard, within easy reach for a right-handed shooter.

The two-position tang safety is intuitive to operate, even with gloved hands. Pushing it forward exposes a red indicator, confirming the rifle is ready to fire. The safety locks the trigger and bolt, preventing accidental discharge while still allowing the bolt to be cycled for unloading. This design is straightforward and reliable, consistent with the rifle’s overall philosophy of no-fuss operation.

Finally, the receiver is drilled and tapped for scope mounting, and the rifle comes with a two-piece scope rail included. This allows you to mount a wide range of optics without additional adapter plates. The .450 Bushmaster is a cartridge that benefits from a low-power variable scope or a red dot for close-range hunting, and the included rail simplifies the setup process. The bolt lift is relatively light, and the action cycles smoothly out of the box, reducing the break-in period often associated with budget-friendly bolt guns.

Ideal Use Cases

Hunting: The .450 Bushmaster is a legal straight-wall cartridge in many Midwestern and Northeastern states for deer hunting. With a 20-inch barrel, you can expect reliable expansion and energy transfer out to 200 yards, making it effective for whitetail, black bear, and feral hogs. The Moss Green finish and synthetic stock hold up well in rain, snow, and mud.

Range Shooting: The Patriot’s adjustable trigger and fluted barrel make it a solid choice for recreational target shooting. The .450 Bushmaster has a manageable recoil compared to magnum calibers, allowing for longer sessions without excessive fatigue. The 5-round magazine is adequate for bench rest or prone shooting.

Not recommended for: Concealed carry, home defense, or competition shooting. The rifle’s length and bolt-action cycle are not suited for close-quarters defensive scenarios or high-speed competitive formats like 3-gun.

Compatibility Notes

  • Ammunition: Uses .450 Bushmaster SAAMI-spec ammunition. Factory loads from Hornady, Federal, and Remington are common. Handloaders should follow published data for .450 Bushmaster.
  • Magazines: Uses Mossberg Patriot-specific 5-round detachable box magazines. Aftermarket extended magazines are not recommended without verification of fit.
  • Optics: Receiver is drilled and tapped for standard Weaver-style bases. The included two-piece rail fits most 1-inch and 30mm scope rings. Low-power variable scopes (1-4x or 2-7x) are a common pairing.
  • Holsters: Not applicable for this rifle.
  • Accessories: Compatible with standard 1-inch sling swivels. Aftermarket muzzle brakes or suppressors must be threaded by a gunsmith, as the barrel is not factory-threaded.
