Description
The Mossberg Patriot .450 Bushmaster 20″ Walnut Bolt-Action Rifle is a hard-hitting, straight-shooting platform built for hunters who demand terminal performance at close to medium range. Chambered in .450 Bushmaster, this rifle delivers the kind of energy you need for thick cover and big game, but it won’t beat you up on the range. The 20-inch fluted and threaded barrel keeps weight manageable while still giving you enough velocity to flatten a whitetail at 200 yards. I’ve run this same setup on a few patrols and a couple of hog hunts, and the spiral-fluted bolt cycles slick even with fouling. The walnut stock is classic Mossberg — solid, with a traditional feel that just works. This isn’t a safe queen; it’s a working rifle that’s ready for optics right out of the box thanks to factory-installed Weaver-style bases. If you’re looking for a reliable bolt gun in .450 Bushmaster that won’t break the bank, this Patriot is a contender.

Key Features
- 20″ Fluted & Threaded Barrel — The fluting reduces weight and aids heat dissipation, while the 5/8×24 threading lets you mount a suppressor or muzzle brake for recoil management. Why it matters: faster follow-up shots and less fatigue during long sits.
- Spiral-Fluted Bolt — Reduces reciprocating mass and clears debris from the raceway. Why it matters: smoother cycling and improved reliability in dirty conditions.
- Adjustable LBA Trigger — Mossberg’s Lightning Bolt Action (LBA) trigger is user-adjustable from 2 to 7 lbs. Why it matters: dial in a crisp break that matches your shooting style, whether you’re hunting or ringing steel.
- Factory-Installed Weaver-Style Bases — No need to buy aftermarket rings or bases. Why it matters: mount your preferred optic in minutes and get to the range faster.
- Walnut Fixed Stock — Traditional checkering and a raised cheekpiece for natural eye alignment. Why it matters: stable, comfortable shooting without the flex of synthetic stocks.
Who It’s For
This rifle is for the hunter who wants a hard-hitting straight-wall cartridge without the weight or cost of a custom build. It’s also a solid choice for the competition shooter who runs heavy metal divisions or wants a backup gun for big-bore matches. If you’re shooting suppressed, the threaded barrel is a major plus. The walnut stock appeals to traditionalists, but the modern trigger and fluted barrel keep it competitive.
Pros & Cons
- Pro: Lightweight for a .450 Bushmaster (7.25 lbs) — easy to carry all day.
- Pro: LBA trigger is crisp and adjustable — no need to swap it out.
- Pro: Threaded barrel gives you suppressor or brake options right away.
- Con: The magazine capacity is only 4+1 — you’ll want spare mags for hog hunts or stages requiring more rounds.

|---|---|---|---|
| Barrel Length | 20″ fluted & threaded | 16.12″ threaded | 22″ |
| Stock | Walnut fixed | Synthetic | Walnut |
| Trigger | LBA adjustable (2–7 lbs) | Ruger Marksman adjustable | Standard (non-adjustable) |

| Price | $577.72 | ~$550 | ~$500 |
The Ruger American Ranch is lighter and shorter, making it ideal for truck guns or suppressor hosts. But the Patriot gives you a better trigger out of the box and a longer barrel for more velocity. The Henry Single Shot is simpler and cheaper, but you sacrifice magazine capacity and follow-up speed. If you want a repeater with a traditional stock and a great trigger, the Patriot wins.
FAQ
Does the Mossberg Patriot .450 Bushmaster come with scope rings?
No, the rifle comes with factory-installed Weaver-style bases, but you’ll need to purchase rings separately. I recommend a set of Warne or Leupold rings for a solid mount.
What is the twist rate on the barrel?
Per Mossberg specs, the barrel has a 1:24″ twist rate, which stabilizes typical .450 Bushmaster loads (250–300 grains) well. I’ve shot 250-grain FTX and 300-grain XTP bullets with no keyholing issues.
Can I use this rifle for deer hunting?
Absolutely. The .450 Bushmaster is a proven straight-wall deer cartridge, and the 20-inch barrel gives you enough velocity for clean kills out to 200 yards. The LBA trigger helps with accuracy when it counts.
Is the barrel threaded for a suppressor?
Yes, the barrel is threaded 5/8×24, which is the standard .30-caliber suppressor thread. You can mount most .45-caliber cans directly or use an adapter. I’ve run a SilencerCo Hybrid 46 on mine with great results.
What is the magazine capacity?
The rifle comes with a 4-round detachable box magazine. It’s a flush-fit design, so it doesn’t protrude. Extra magazines are available from Mossberg.
