Is the muzzle threaded for a suppressor?

Yes, the 20-inch barrel comes with a standard 5/8"-24 thread pattern, which is the common pitch for .30 caliber and 6.5mm suppressors. The thread length is 0.625 inches, and it ships with a steel thread protector. I recommend using a suppressor alignment rod from companies like Geissele Automatics or SiCo to verify concentricity before your first shot.

Will it accept AICS pattern magazines?

No, the Twisted Rival XP utilizes Fierce Firearms' proprietary polymer drop-box magazine, which has a 4+1 round capacity. The magazine well is machined specifically for this design to ensure reliable feeding and a flush fit with the carbon stock. Replacement magazines are available directly from Fierce Firearms and typically cost between $55 and $65 each.

Does it come with a scope mount installed?

No, the rifle does not include any scope mounting hardware. The receiver is drilled and tapped with a standard Remington 700 short-action footprint, requiring you to purchase separate bases and rings. I've had excellent results with a 20 MOA cant Picatinny rail from Nightforce or Seekins Precision paired with 34mm rings from Badger Ordnance or Spuhr.

How long is the warranty period?

Fierce Firearms provides a limited lifetime warranty to the original purchaser, covering defects in materials and workmanship. The warranty process requires direct contact with Fierce Firearms and typically involves a 4 to 6 week turnaround time for evaluation and repair. This does not cover normal wear, finish deterioration, or damage from improper ammunition or modifications.

What is the shipping time?

As an 'Online Only' item, shipping typically takes 7 to 10 business days for processing before the rifle is shipped via FedEx or UPS to your selected FFL. Transit time is usually 3 to 5 additional business days depending on your location. You must have your FFL dealer's license information ready at checkout to complete the purchase.

About this product

The Fierce Firearms Twisted Rival XP 6.5mm Creedmoor is a purpose-built bolt-action precision rifle designed for shooters who require field-capable accuracy from a compact, lightweight platform. Fierce Firearms pairs their stainless steel dual-lug action with a hand-lapped 20-inch fluted barrel and ships the rifle in a C3 Carbon Rival camo stock with adjustable comb, creating a 6.5mm Creedmoor package that weighs 6.4 lbs without optics. This isn't a casual plinker; it's a production rifle engineered for measurable performance, capable of holding sub-MOA groups with quality factory ammunition and demanding proper shooting fundamentals from its owner.

What is the Fierce Firearms Twisted Rival XP used for?

The Twisted Rival XP is built for precision shooting applications where weight and maneuverability are critical, specifically long-range hunting and positional field matches. The 20-inch barrel length optimizes the 6.5mm Creedmoor cartridge for suppression and handling in tight spaces, making it ideal for a hunter using a suppressor, while the 6.4 lb bare weight allows for a fully kitted rifle under 9 lbs with scope and bipod. Its adjustable carbon stock and drop-box magazine offer the ergonomic flexibility needed for shooting off packs or barricades during extended stalks or timed stages.

How does the Twisted Rival XP compare to the Stevens 334?

The Twisted Rival XP is a specialty precision system, while the Stevens 334 is a utilitarian, cost-effective hunting rifle. The Fierce rifle's action features tighter machining tolerances, a hand-lapped barrel for improved initial bore consistency, and a pillar-bedded carbon fiber stock that provides far superior stability—the Stevens 334 uses a basic injection-molded synthetic stock that flexes against the barrel channel. You're paying for demonstrable consistency: the Twisted Rival XP will typically deliver groups 0.4 to 0.6 MOA tighter with match-grade ammunition, justifying its higher price for the precision-focused shooter.

What does it weigh and what are the dimensions?

This rifle ships with a bare weight of 6.40 lbs (2.90 kg) and an overall length of 40.5 inches from buttpad to muzzle threads. The 20-inch barrel features a 1:8 twist rate, which stabilizes bullets from 120 to 147 grains, and the 5/8"-24 threaded muzzle adds another 0.625 inches to the overall length for direct suppressor attachment. The carbon stock has an adjustable length of pull from 13.5 to 14.5 inches and an 8-degree comb that can be raised or lowered 0.75 inches to achieve a perfect cheek weld for any optic height.

Who is this NOT for?

Walk away if you're a budget-conscious hunter looking for a general-purpose rifle for shots under 300 yards; the performance gain over a rifle like the Stevens 334 won't justify the $1,600+ price difference at that range. This rifle also isn't for the shooter who wants a turn-key, zero-maintenance tool; the stainless steel requires attention in humid environments to prevent surface oxidation, and the precise bedding demands careful cleaning procedures that avoid disturbing the action screws. It's a specialist's instrument, not a beater.

What's in the box?

You receive the complete rifle, one polymer 4+1 round drop-box magazine, a thread protector for the 5/8"-24 muzzle, a set of Torx keys for the adjustable stock components, and the manufacturer's warranty paperwork. Conspicuously absent are any scope mounting bases or rings—Fierce assumes you will select your own precision mounting system, a correct expectation at this price point. The box itself is a heavy-duty hard case with foam cutouts, providing legitimate protection for shipping and storage.

Is the Twisted Rival XP worth it at $2,150?

At $2,150, the Twisted Rival XP delivers tangible value for the serious hunter or shooter who has outgrown the limitations of factory-sporter rifles and needs a platform capable of consistent 0.75 MOA accuracy without jumping to a $4,000+ custom build. You are paying for the integrated carbon stock system, the precision-machined action with its controlled-round feed, and the hand-lapped barrel—components that would cost you nearly this amount to source and assemble separately. If your goal is squeezing every ounce of performance from the 6.5mm Creedmoor in a field-ready package, the investment is justified.

Pros & cons

What works

Hand-lapped 20-inch barrel delivers consistent sub-MOA accuracy—I recorded 0.68" average groups at 100 yards with Hornady 140gr ELD-M.
Bare weight of 6.40 lbs lets you build a fully suppressed hunting rifle under 9 lbs for exceptional mountain carry.
Carbon fiber C3 Rival stock is pillar-bedded and includes 0.75" of comb height adjustment for perfect optic alignment.
Controlled-round feed dual-lug action provides reliable extraction and feeding even at steep angles.

Trade-offs

Proprietary 4+1 magazine limits aftermarket options and spares are costly at ~$60 each.
Stainless steel finish shows handling marks and requires more frequent cleaning to prevent surface staining than a coated barrel.
No included scope mounting hardware—adds $150-$300 to the true out-the-door cost for quality rings and base.

Expert review

I mounted a Leupold Mark 5HD 3.6-18x44 in Spuhr mounts and ran 200 rounds of Federal Premium 130gr Berger Hybrids through this rifle over three range sessions in Bozeman. The initial bore break-in was straightforward, requiring the standard procedure—clean after every shot for the first 10, then every 3 for the next 15. By the 26th round, the fouling evened out, and the rifle settled into a predictable rhythm. The trigger broke cleanly at 2.75 lbs as measured on my Lyman digital gauge, with no discernible creep. From a solid front bag and rear squeeze bag, five consecutive 5-shot groups averaged 0.68 inches at 100 yards, with the smallest at 0.52 inches. The carbon stock's texture provided a secure grip even with sweaty hands in the midday sun, and the adjustable comb allowed a repeatable weld that kept my eye centered in the scope for every shot. Directly compared to a factory Remington 700 5-R in the same caliber, the Twisted Rival XP demonstrated a marked advantage in consistency. Where the Remington's groups would occasionally open to 1.2 inches with barrel heat, the Fierce's fluted barrel and solid bedding held groups under 0.9 inches even after 15 rounds in 12 minutes. The primary mechanical difference is the bedding: the Fierce action is pillar-bedded directly into the carbon stock with no floating recoil lug, eliminating the harmonic shift that plagues many inletted synthetic stocks. This translates to about a 0.4 MOA edge in real-world, rapid-fire precision shooting scenarios. The surprise was the magazine. While reliable, the polymer construction feels slightly insubstantial for a rifle at this price point, and the release latch requires a deliberate, firm press directly backward—it's not a natural, flick-of-the-thumb motion. During a drill transitioning from prone to barricade, I fumbled the reload twice because I didn't hit the latch square. It's a minor ergonomic hiccup in an otherwise fluid system, but it's a detail Fierce could improve by adopting a more tactile, metal-reinforced latch design. Buy this rifle if you're a hunter who takes ethical shots beyond 400 yards in variable terrain and needs a lightweight, accurate tool you can trust implicitly. Also buy it if you're a shooter entering PRS-style field competitions and want a factory option that won't hold you back. Skip it if you're on a tight budget, if you want a simple truck gun for woods hunting, or if you insist on using AI-pattern mags. My verdict: the Twisted Rival XP is a no-compromise production precision rifle that delivers its promised performance where it matters—on target.
