Description
Straight-wall cartridges have earned their place in the deer woods, and the .400 Legend takes the concept a step further with more energy than the .350 Legend while keeping recoil manageable. Mossberg chambered the Patriot for it and got the details right: a 20 inch fluted barrel with a recessed match crown, threaded 11/16×24 so you can run a suppressor or muzzle device without a trip to the gunsmith. The 1:16 twist stabilizes the heavy .40 caliber bullets this cartridge was built around, and the compact 40.75 inch overall length handles well in a box blind or thick timber.
What Makes the Patriot .400 Legend Worth a Look
The LBA trigger is the standout here. It adjusts from roughly 2 to 7 pounds with a simple screw, so you can dial in a clean, crisp break instead of living with whatever the factory sends. The spiral-fluted bolt with its knurled handle cycles smoothly and sheds grit, and the detachable 4-round box magazine drops free for quick, safe loading and unloading. Weaver-style two-piece bases come installed from the factory, meaning you just add rings and glass and head to the range to zero. At around 6.5 pounds bare, it carries easily on a long walk to the stand.
Built for Real Hunting Conditions
The matte blued barrel and receiver keep glare down, and the fixed black synthetic stock shrugs off rain, cold, and the dings that come with actual field use. There is nothing delicate about this setup. It is the kind of rifle you can toss in the truck in November and not worry about.
A Smart Pick for Straight-Wall Country
For hunters in areas where straight-wall cartridges are the go-to choice, this Patriot delivers plenty of knockdown power for whitetail and hogs inside 200 yards. Pair it with a modest 3-9x scope and a can on the muzzle, and you have a quiet, soft-shooting deer rig that will not break the bank or your shoulder.

Frequently Asked Questions
Does the Mossberg Patriot .400 Legend come with sights or a scope?
No iron sights or scope are included. The receiver comes with Weaver-style two-piece bases already installed, so all you need is a set of rings and your optic of choice. Most buyers pair it with a 3-9x hunting scope and are ready to zero the same day.
Is the barrel on this Patriot suppressor ready?
Yes. The 20 inch fluted barrel is threaded 11/16×24, which is the common thread pattern for .40 caliber straight-wall rifles like the .400 Legend and .450 Bushmaster. It ships with the muzzle threaded from the factory, so mounting a suppressor or brake is simple.
Can I adjust the trigger on the Mossberg Patriot?
You can. Mossberg's LBA (Lightning Bolt Action) trigger is user adjustable from roughly 2 to 7 pounds using a simple screw adjustment. It also has a blade safety in the shoe for a crisp, creep-free pull, which is a big part of why the Patriot punches above its weight for accuracy.
What is the .400 Legend good for compared to the .350 Legend?
The .400 Legend is essentially the .350's bigger brother, throwing a heavier .40 caliber bullet with noticeably more energy while still keeping recoil mild for a big-bore round. It is a great fit for whitetail and hogs at typical woods distances, generally inside 200 yards. If you hunt straight-wall country and want more thump without stepping up to a .450 Bushmaster, this cartridge hits a sweet spot.
