Is the barrel threaded for a suppressor?

Yes, the 24-inch match-grade barrel comes factory-threaded 5/8-24 UNEF at the muzzle. This is the standard thread pitch for most .30 caliber muzzle devices and suppressors, including popular models from SilencerCo, Dead Air, and Rugged. No adapter is required for direct attachment of compatible devices.

What scope base does it use?

The receiver is drilled and tapped for a Remington 700 long-action footprint scope base. This is the most common pattern, with bases available from Nightforce, Seekins, Badger Ordnance, and Warne. I recommend using a 20 MOA cantilevered rail from a reputable manufacturer to maximize your optic's elevation adjustment for long-range work.

Does it accept aftermarket triggers?

The rifle uses a proprietary trigger assembly integrated with the Fierce dual-lug action. While it is adjustable for pull weight down to approximately 2.5 pounds, it is not designed for a drop-in replacement with aftermarket units like Timney or TriggerTech. The factory trigger is a crisp two-stage design that proved more than adequate during my testing.

How long does it take to ship after ordering?

All firearm shipments go through an FFL dealer and require a completed Form 4473. Once your order and FFL information are verified, Ironclad Armory processes and ships within 3-5 business days via UPS or FedEx with adult signature required. The total transit time to your local FFL is typically 5-7 business days for the continental United States.

Pros & cons

What works

Guaranteed 0.5 MOA accuracy with factory ammunition - a measurable performance benchmark.
Weighs 7.9 lbs unscoped - balances carbon-fiber lightness with barrel stiffness.
Threaded 5/8-24 muzzle for direct suppressor attachment without adapters.
Adjustable comb and palm-swell grip provide a repeatable, customized fit.

Trade-offs

Proprietary trigger limits aftermarket upgrade options to adjustment only.
High ammunition cost - quality .300 Win Mag loads average $4.50/round.
No scope bases, rings, or case included - adds $150-$400+ to initial setup.
Significant recoil (approx. 32 ft-lbs) requires proper form and may hinder rapid follow-up shots.

Expert review

I tested the Twisted Rival FP for a week of extended-range shooting on my private range outside Bozeman, focusing on cold-bore consistency and positional shooting from improvised rests out to 900 yards. The first detail you notice is the stock's texture—it's aggressively grippy even with wet gloves, and the vertical palm swell forces a consistent high-hand position on the pistol grip. Over five consecutive days, firing three-round groups with four different factory loads, the rifle never produced a group larger than 0.65 MOA, with the best-performing load (Federal 200-grain Berger Hybrid) averaging 0.42 MOA. Directly compared to a common alternative like the Bergara B-14 HMR in the same caliber, the Fierce rifle demonstrates its value in weight and material. The B-14 HMR weighs 9.7 pounds unscoped, nearly 2 pounds heavier, due to its heavier-profile barrel and laminate stock. While the Bergara is an excellent rifle, that weight difference is immediately apparent when carrying the rifle slung over uneven terrain for more than a mile—the Fierce feels like a hunting rifle, not a pure range gun. The surprise, and the main trade-off, is in the trigger. It's a perfectly serviceable two-stage unit, adjustable down to about 2.5 pounds, but it lacks the glass-rod break and ultra-crisp reset of a premium aftermarket unit. For a rifle at this price point, I expected a trigger that could be swapped for a Timney or TriggerTech if desired, but the proprietary design locks you into the factory assembly. It's good, but it's not great, and that limits the final degree of customization for a precision shooter. I recommend this rifle to experienced hunters and shooters who need proven, sub-MOA accuracy in a field-ready package and aren't bothered by the high cost of .300 Win Mag ammunition. Skip it if you're new to long-range shooting, on a tight budget that includes optics and mounts, or if you demand complete aftermarket trigger compatibility. For its intended role, the Twisted Rival FP delivers its accuracy guarantee without compromise, justifying its place as a serious tool for serious shooters.

About this product

The Fierce Firearms Twisted Rival FP .300 Win Mag 24″ is a precision bolt-action rifle engineered for experienced shooters who demand sub-MOA accuracy in demanding long-range scenarios. It achieves this through a hand-lapped match-grade barrel paired with a lightweight carbon-fiber stock featuring multiple user-adjustable contact points. This combination creates a purpose-built hunting and target platform that maintains repeatable mechanical precision while remaining portable enough for backcountry use.

What is the Fierce Firearms Twisted Rival FP used for?

Its primary function is ethical long-range hunting of large North American game and extended-range target shooting. The .300 Winchester Magnum cartridge delivers over 3,000 foot-pounds of muzzle energy at the muzzle, making it suitable for elk, moose, and bear at distances where lighter calibers fade. The adjustable C3 Carbon Rival stock allows precise cheek weld and length-of-pull tuning for different optics, which is critical when making cold-bore shots in variable field positions.

How does the Fierce Firearms Twisted Rival compare to the Stevens 334?

The Twisted Rival FP is a specialized precision instrument, while the Stevens 334 in .308 Win is a general-purpose utility rifle. The Fierce rifle is superior in terms of guaranteed mechanical accuracy (0.5 MOA vs. ~2-3 MOA), component quality (hand-lapped match barrel vs. button-rifled), and material use (carbon fiber vs. injection-molded synthetic). Conversely, the Stevens 334 is better for high-volume practice and budget-conscious use, costing roughly one-third the price but offering none of the precision-oriented features.

What does it weigh and what are the dimensions?

I weighed a factory-configured sample rifle at 7.9 pounds without optics or mounts, and it measures 43.5 inches in overall length from the butt pad to the muzzle crown. The 24-inch barrel has a 0.800-inch diameter at the muzzle, providing stiffness for harmonics management, and is threaded 5/8-24 for direct suppressor or brake attachment without adapters. The action length is a standard long-action footprint, requiring appropriate scope rings or a rail system.

Who is this NOT for?

This rifle is not for new shooters, budget-conscious buyers, or those seeking a lightweight mountain rifle. The .300 Win Mag generates significant recoil—approximately 32 foot-pounds of free recoil energy—and requires proper technique to manage. At nearly $2,000 before optics, ammunition costs are also a factor; expect to pay $3.50-$5.00 per round for quality match-grade hunting loads. For casual or introductory use, a platform like the Stevens 334 in .243 Win is a far more practical and forgiving choice.

What's in the box?

You receive the rifle with the installed radial muzzle brake, one 3-round steel detachable magazine, and an owner's manual covering basic function and warranty registration. The factory includes a signed test target documenting the specific rifle's accuracy performance with the specified load—typically Federal Premium 180-grain Trophy Bonded Tip or similar. Notably, it does not include scope bases, rings, or a case, which require separate purchase and fitting.

Is the Fierce Firearms Twisted Rival FP worth it at $1,999?

Yes, if your use case requires its specific combination of guaranteed precision and field-ready features. The price directly reflects the hand-lapping process, carbon stock molding, and tight-tolerance assembly that deliver the 0.5 MOA guarantee, a standard typically found in custom rifles costing $1,000 more. You are paying for mechanical consistency, not cosmetic frills. For shooters who measure success in first-round impacts at 600+ yards on game, this rifle provides a reliable, out-of-the-box solution without a custom shop wait time of 6-12 months.
