Description
The Mossberg Patriot Carbine .300 Win Mag 20″ Threaded is a compact bolt-action rifle built for hunters and competition shooters who need a hard-hitting, portable platform. It pairs a 20-inch medium bull barrel with a fixed synthetic stock, keeping weight down without sacrificing the .300 Win Mag’s long-range authority. The barrel is threaded 5/8″-24 TPI, ready for brakes or suppressors, and the receiver comes drilled and tapped with a top-mounted Picatinny rail for optics. At $421.99, this is a budget-friendly entry into a serious caliber.

Key Features
- Threaded Medium Bull Barrel: The 20-inch barrel is threaded 5/8″-24 TPI. Why it matters: You can mount a muzzle brake to tame recoil or a suppressor for quieter shooting, both critical for extended range sessions or hunting in noise-sensitive areas.
- Fixed Synthetic Stock: The stock is a one-piece, black synthetic design. Why it matters: It’s weatherproof and rigid, maintaining zero in rain or snow, and the fixed design eliminates the slop you get with adjustable stocks at this price point.
- Picatinny Rail Included: The receiver is drilled and tapped with a top-mounted Picatinny rail. Why it matters: No need to buy a separate base—mount your scope directly and get a solid, repeatable zero without guesswork.
- Matte Blue Finish: The metalwork is finished in matte blue. Why it matters: Reduces glare in the field, helps resist corrosion, and keeps the rifle looking functional rather than flashy.
- Compact 20-Inch Barrel: At 20 inches, this is a carbine-length barrel for a magnum cartridge. Why it matters: You get the power of .300 Win Mag in a package that’s easier to maneuver in tight brush or from a blind, without giving up too much velocity.
Who It’s For
This rifle is for the hunter or precision shooter who wants a lightweight, hard-hitting bolt gun without dropping a grand. It’s ideal for elk, moose, or long-range steel out to 600 yards. The compact build also appeals to suppressor users who need a short overall length. If you’re a competition shooter looking for a budget .300 Win Mag to practice with, this is a solid starting point.
Pros & Cons
- Pro: Price—$421.99 is hard to beat for a threaded .300 Win Mag bolt gun.
- Pro: Ready for optics with the included Picatinny rail.
- Con: The synthetic stock feels a bit hollow and could benefit from a bedding job for maximum accuracy. Per Mossberg’s specs, the stock is a basic unit, but it’s functional for hunting.
Comparison
| Feature | Mossberg Patriot Carbine .300 Win Mag | Ruger American Hunter .300 Win Mag | Remington 700 SPS .300 Win Mag |
|---|---|---|---|
| Barrel Length | 20″ threaded | 22″ threaded | 24″ (non-threaded) |
| Weight | 7.25 lbs | 8.4 lbs | 7.5 lbs |
| Stock | Fixed synthetic | Adjustable synthetic | Synthetic |
| Price | $421.99 | $599.00 | $649.00 |
| Optics Mount | Picatinny rail included | Drilled and tapped | Drilled and tapped |
The Ruger American Hunter offers an adjustable stock and a slightly longer barrel, but at a higher price. The Remington 700 SPS is a classic but lacks threading and costs more. The Mossberg wins on value and compactness.
FAQ

Yes. The barrel is threaded 5/8″-24 TPI, which is the standard for .30 caliber suppressors and muzzle brakes.
What scope base does it use?

How accurate is this rifle out of the box?
Expect sub-MOA groups with quality factory ammunition. The 20-inch barrel and medium bull profile help with consistency, but the basic stock may require some bedding for maximum precision.
