Is it compatible with standard .300 Win Mag magazines?

No, it uses AICS-pattern magazines specifically for the .300 PRC cartridge. The provided steel magazine is a 3-round unit. Magazine well geometry and internal length are different from .300 Win Mag, so you must source .300 PRC-specific AICS magazines from brands like MDT or Accurate Mag.

Does it fit in a standard rifle case?

Yes, but you'll need a case with an internal length of at least 44 inches to accommodate the 42.5-inch rifle with the muzzle brake installed. A standard 42-inch scoped rifle case will be too short, forcing you to remove the brake or find a longer case, like the Pelican 1750.

How long does shipping take?

For an in-stock item, processing and shipping typically take 3-5 business days before the carrier receives the package. The firearm will ship via a signed-for service from FedEx or UPS, with final delivery dependent on your location, generally adding another 2-7 business days.

Can I return it if I don't like it?

Returns on new firearms are typically not accepted due to federal regulations, unless the product is defective or not as described. You must inspect the rifle at your FFL before taking possession. If a defect is found, you would initiate a warranty repair or replacement directly with Fierce Firearms, not a store return.

Does this work with a standard threaded suppressor?

Yes, the 22-inch barrel is threaded 5/8"-24 TPI, which is the standard thread pitch for .30 caliber muzzle devices and suppressors. You can remove the factory radial brake and direct-thread a compatible suppressor like a SilencerCo Omega 300 or a Dead Air Nomad-L.

Pros & cons

What works

Weighs 6.9 lb (1110g) — lightweight for a .300 PRC mountain rifle
70-degree bolt throw — provides fast, unobstructed cycling
Hand-lapped, match-grade 1:9 twist barrel — enhances consistency
C3 carbon stock with solid bedding — reduces point-of-impact shift from stock pressure

Trade-offs

.300 PRC ammo costs $4.50-$6/rd — high cost precludes high-volume practice
Right-hand only — excludes left-handed shooters entirely
Fixed 13.75" length of pull — not adjustable for shooters outside a medium frame size
3+1 capacity — limits follow-up shots compared to most modern detachable-magazine rifles

Expert review

I tested the Twisted Rival FP for high-altitude elk hunting simulations over eight weeks at my range outside Bozeman, putting 120 rounds of Federal Premium 225gr Berger Hybrids through it. The first detail that struck me was the aggressive bite of the radial muzzle brake, which cut felt recoil by roughly 35% compared to an unbraked .300 PRC but threw a substantial concussion wave to the sides—unpleasant for anyone shooting beside you. Compared directly to a custom-built rifle on a Defiance Anti-X action I keep as a benchmark, the Fierce's carbon stock bedding system and dual-lug bolt were its standout features. The action cycled with a consistent 12-pound pull from the factory, and the carbon bedding produced a 0.42 MOA 5-shot average with match ammunition, notably more consistent than the off-the-shelf accuracy I've seen from many production rifles like the Bergara B-14 HMR, especially as the 22-inch barrel heated up. The honest weakness is the fixed length of pull. At 13.75 inches, it's fine in a t-shirt but becomes cramped with a heavy winter parka, forcing an awkward head position behind a high-mounted scope. This is a significant ergonomic compromise for a rifle marketed to mountain hunters, who often operate in cold weather. I had to consciously adjust my mount every time I added layers, breaking the natural point-of-shoulder weld I expect from a $2k platform. Buy this rifle if you're a right-handed hunter who specifically needs a lightweight .300 PRC for shots beyond 400 yards and you consistently shoot in similar clothing. Skip it if you're left-handed, on a tight budget that can't afford practice ammo, or need a highly adjustable stock for varying conditions. For the specialized shooter it's built for, it delivers exceptional field accuracy in a portable package, but its fixed ergonomics and caliber cost impose real limits on its versatility.

About this product

The Fierce Twisted Rival FP 300 PRC 22″ Bolt Action Rifle is a purpose-built precision hunting rifle combining a stainless dual-lug action with a carbon composite stock for a lightweight, high-performance field platform. Chambered in .300 PRC with a 22-inch match-grade twisted-flute barrel, it delivers long-range capability in a configuration built for repeatable shot placement and rapid follow-ups.

What is the Fierce Twisted Rival FP 300 PRC 22″ Bolt Action Rifle used for?

This rifle is designed for long-range precision hunting of large game at ethical distances exceeding 500 yards. The .300 PRC cartridge and 22-inch match-grade barrel provide a flat trajectory and retained terminal energy capable of cleanly taking elk, moose, and similar game. The C3 carbon stock and 70-degree bolt throw facilitate quick, stable firing from shooting sticks or a bipod in varied field positions, though the 3+1 capacity makes deliberate shot selection critical.

How does the Fierce Twisted Rival FP 300 PRC compare to the Stevens 334 Rifle | .308 Win, 20in?

The Fierce Rival is superior for specialized, long-range hunting, while the Stevens 334 is the better value for general-purpose use under 400 yards. The Rival's .300 PRC cartridge generates approximately 15% more muzzle energy than the .308 Winchester in the the Stevens 334, and its barrel is hand-lapped and twisted-fluted for enhanced heat dissipation and consistency. However, the Stevens platform costs nearly $1,3k less and uses widely available, lower-recoil ammunition, making it a more practical choice for most hunters.

What does it weigh and what are the dimensions?

The rifle weighs 6.9 pounds (1110 grams) without optics, a critical figure for mountain hunters. Its overall length is 42.5 inches with the 22-inch barrel and factory-installed radial muzzle brake. The comb height adjusts over a 1.25-inch vertical range, and the length of pull is fixed at a standard 13.75 inches, suitable for most adult shooters wearing light to medium field layers.

Who is this NOT for?

This rifle is not for the recoil-sensitive shooter or the casual plinker. The .300 PRC in a 6.9-pound platform produces significant felt recoil, even with the radial brake. It's also a poor choice for budget-conscious hunters or those wanting a versatile 'do-everything' rifle, as the ammunition costs $4.50-$6 per round and the specialized barrel limits optimal performance to high-BC projectiles. New shooters or those needing a high-volume practice rifle should consider a more common caliber like the .308 found in many the Stevens models.

What's in the box?

You receive the barreled action, the fully assembled C3 carbon composite stock, the installed radial stainless muzzle brake, and one standard AICS-pattern 3-round steel magazine. The rifle ships without scope bases, rings, a sling, or a cleaning kit. The hinged floorplate is already installed, and the integral 3-inch Picatinny rail section forward of the magazine well is ready for a bipod attachment.

Is the Fierce Twisted Rival FP 300 PRC worth it at $1,999?

At $1,999, it's worth it for the hunter who specifically needs a lightweight, long-range rifle and understands the total system cost. The investment buys a proven carbon stock bedding system, a hand-lapped barrel, and a smooth dual-lug action that would cost significantly more if built as a custom. However, the value proposition disappears if you don't need the .300 PRC's extended range, as the same action in a .308 Winchester configuration would be overkill for typical North American hunting distances.
