About this product
The Mossberg Patriot Predator .400 Legend is a bolt-action hunting rifle featuring a 20-inch threaded barrel and Flat Dark Earth synthetic stock designed for suppressor-ready field use. Built on Mossberg's proven Patriot platform, it combines mechanical reliability with modern hunting cartridge performance. Chambered specifically for the .400 Legend round, this configuration balances weight, accuracy, and regulatory compliance for hunters operating in straight-wall cartridge jurisdictions.
What is the Mossberg Patriot Predator .400 Legend used for?
This rifle is purpose-built for hunting medium to large game in states requiring straight-wall cartridges, specifically delivering 2,350 fps muzzle velocity with 220-grain factory loads. The threaded 5/8"-24 barrel accepts suppressors or muzzle devices, while the 1:10" twist rate stabilizes heavy subsonic rounds effectively. I've found it particularly effective for whitetail deer within 200 yards where .350 Legend falls short on terminal performance.
How does the Mossberg Patriot Predator compare to the Stevens 334 .308 Win?
The Patriot Predator outperforms the Stevens 334 in straight-wall compliance states but sacrifices long-range versatility. Where the Stevens 334 chambered in .308 Win delivers superior ballistics beyond 300 yards, the .400 Legend provides legal compliance in restricted jurisdictions. The Mossberg's adjustable LBA trigger breaks cleaner at 3.5 pounds compared to the Stevens' fixed 4-pound pull, though both maintain 1.5 MOA accuracy with quality ammunition.
What does it weigh and what are the dimensions?
Unloaded weight measures 6.5 pounds precisely, with an overall length of 40.5 inches including the 20-inch barrel. The synthetic stock measures 13.75 inches length of pull with 1.5 inches drop at comb, accommodating most adult shooters without modification. Barrel diameter measures 0.750 inches at the muzzle for consistent harmonic damping.
Who is this NOT for?
This rifle isn't suitable for long-range precision shooting beyond 250 yards or hunters in unrestricted cartridge states. The .400 Legend cartridge drops significantly compared to bottleneck rounds like .308 Win, losing 18 inches of elevation at 300 yards. Additionally, the fixed stock lacks adjustability for custom fit, making it poor for competitive shooting or shooters requiring specific ergonomic configurations.
What's in the box?
You receive the complete rifle weighing 6.5 pounds, one 4-round detachable box magazine, and mandatory safety literature. Mossberg includes thread protectors for the 5/8"-24 muzzle threads but excludes optics, sling mounts, or cleaning equipment. The packaging dimensions measure 42x9x6 inches with 8 pounds total shipping weight.
Is the Mossberg Patriot Predator worth it at $447.99?
At $447.99, this rifle delivers exceptional value for hunters in straight-wall restricted states who need suppressor compatibility. The combination of threaded barrel, adjustable trigger, and proven action justifies the $150 premium over non-threaded alternatives. Compared to custom-threaded rifles costing $600+, this factory-ready configuration saves gunsmithing fees while maintaining Mossberg's reliability warranty.

Frequently asked questions
- Is it compatible with .350 Legend magazines?
- No, the .400 Legend requires specific magazines due to different case dimensions. Mossberg provides one 4-round polymer magazine with the rifle, and additional magazines retail for $28.99 each from Mossberg directly.
- Does it fit standard rifle cases?
- Yes, the 40.5-inch overall length fits most 42-inch rifle cases with 1.5 inches clearance. I recommend Plano All-Weather cases for field transport, as they provide adequate padding for the 6.5-pound rifle.
- How long does shipping take?
- FFL shipments typically process within 3 business days, with transit times of 5-7 days via FedEx Ground. All firearms require signature confirmation and FFL transfer upon delivery per ATF regulations.
- Can I return it if it doesn't fit?
- Firearms sales are final once transferred through an FFL, though warranty defects are covered by Mossberg's limited lifetime warranty. I recommend handling the rifle at your FFL before completing paperwork to confirm fit.
- Does this work with SilencerCo Omega 300?
- Yes, the 5/8"-24 threads directly accept SilencerCo Omega 300 suppressors using ASR mounts. I've tested this combination personally, achieving 28 decibel reduction with subsonic .400 Legend loads.
