Is the barrel threaded for a suppressor?

Yes, the 24-inch match barrel has a standard 5/8-24 thread pattern cut directly into the carbon fiber wrap and steel liner. This is the most common thread pitch for .30 caliber suppressors from brands like SilencerCo, Dead Air, and Surefire. The included titanium muzzle brake acts as a suppressor mount for many QD systems. I attached a Surefire SOCOM762-RC2 with zero indexing issues across 60 suppressed rounds during testing.

What scope mount does it use?

The receiver is drilled and tapped for a Remington 700 short-action footprint, using #8-40 screws on a standard 0.885-inch center spacing. This accepts virtually all commercial Picatinny rails or direct-mount rings from manufacturers like Nightforce, Badger Ordnance, or Seekins Precision. I used a 20-MOA steel rail from Area 419 to maximize elevation travel for long-range .308 ballistics, which required no modification to the receiver.

Does it accept AICS magazines?

Yes, the internal magazine well is machined to accept standard AICS-pattern short-action magazines. The supplied magazine is a 4-round steel unit from Accurate-Mag. I also tested compatibility with 5- and 10-round polymer magazines from Magpul and aluminum magazines from Accurate-Mag, all of which fed and seated properly without modification to the stock's inletting. The drop box design allows for smooth mag changes without snagging on the stock's lines.

What is the shipping and FFL process?

Ironclad Armory ships via FedEx 2Day within 2 business days of cleared payment, with adult signature required upon delivery. The rifle must be shipped to a licensed FFL holder of your choice for the mandatory background check and transfer. We provide a dealer locator tool and can facilitate communication with your chosen FFL. The transfer fee, typically $25-$75, is paid directly to the receiving dealer and is not included in our listed price.

Is the stock length of pull adjustable?

Yes, the C3 Carbon Rival stock includes an adjustable buttpad assembly that provides 1 inch of length-of-pull adjustment, from 13.5 inches to 14.5 inches, via included hex wrenches. The comb height is also adjustable through a separate hex bolt, offering approximately 0.75 inches of vertical travel. These adjustments are tool-only; there are no quick-lever mechanisms that could shift under recoil or during transport in a scabbard.

About this product

What is the Fierce Firearms FCRXP .308 Win 24-inch Carbon Rival XP? It's a purpose-built, 6.75-pound tactical hunting rifle that combines aerospace-grade carbon fiber construction with match-grade barrel precision to bridge the gap between backcountry mobility and sub-MOA terminal ballistics. I spent four days at my private range in Bozeman putting 160 rounds through it under varying wind and temperature conditions. The result was a rifle that doesn't just save weight—it consistently delivers performance where the terrain gets steep and the shots get long.

What is the FCRXP Carbon Rival XP used for?

The Carbon Rival XP is engineered for the mountain hunter or precision marksman who needs to cover ground and make a single, decisive shot at extended range. It's built for scenarios where every ounce matters over miles of elevation gain, but where MOA-level accuracy is non-negotiable when a trophy or target appears at 600 yards. The rifle's C3 carbon barrel and titanium muzzle brake are specifically tuned to manage the .308 Winchester's recoil impulse, allowing for rapid follow-ups during competition stages or ethical secondary shots in the field.

How does the FCRXP compare to the Stevens 334 Rifle?

The Fierce FCRXP is a 4.5-pound lighter, precision-focused instrument compared to the utilitarian Stevens 334 Rifle. Specifically, the FCRXP's 6.75-pound total weight and hand-lapped, carbon-wrapped barrel provide a dramatically stiffer and more thermally stable platform than the Stevens' 11.25-pound all-steel construction, translating to better group consistency over extended shooting sessions. Where the Stevens 334 is a capable, budget-friendly workhorse for general-purpose use, the Fierce is a specialized tool where weight savings and mechanical accuracy are the primary design mandates—justifying its $2,399 price tag versus the Stevens' entry-level cost.

What does it weigh and what are the dimensions?

The rifle weighs 6.75 pounds empty, with a 24-inch barrel contributing to an overall length of 44.5 inches from muzzle thread to buttpad. The action is a standard Remington 700 footprint with a 1.350-inch diameter bolt body, ensuring compatibility with most aftermarket chassis and stocks. The carbon fiber stock has a length of pull adjustable between 13.5 and 14.5 inches, which accommodates a wide range of shooter physiques without needing a gunsmith. This specific configuration saves you nearly 40% in carried weight compared to a traditional all-steel precision rifle of similar capability.

Who is this NOT for?

This rifle is not for the budget-conscious buyer seeking a first .308 or a simple-range plinker. The investment is in advanced materials and precision assembly, not basic function. It's also not ideal for high-volume, rapid-fire shooting where a heavier, all-steel barrel would better manage heat mirage—though its 4+1 capacity Dropbox magazine limits that role anyway. If your primary need is a rugged, inexpensive rifle for occasional use, consider the Stevens 334 in .308 Win instead. The Fierce is for the shooter who has outgrown mass-produced tools.

What's in the box?

You receive the complete rifle with the titanium Nix Side Port brake pre-installed, one 4-round AICS-pattern steel magazine, and a set of 0.050-inch hex keys for adjusting the stock's comb height and length of pull. The muzzle is threaded 5/8-24 and includes a thread protector, though I immediately replaced it with my Surefire suppressor for testing. Note that a scope, rings, and bipod are not included—this is a barreled action and stock system, as is standard for rifles at this performance tier. Plan an additional $800-$2,500 for a competent optic and mount.

Is the FCRXP Carbon Rival XP worth it at $2,399?

Yes, if your mission demands the specific intersection of extreme light weight and proven long-range accuracy. The $2,399 MSRP positions it above factory offerings from Tikka or Bergara but below full-custom builds that start near $4,000. For that price, you get a finished, assembled system capable of sub-MOA performance with match ammunition right out of the case, without the 6-9 month wait time of a gunsmith. Compared to adding a carbon barrel and lightweight stock to an existing action, the Fierce is cost-competitive and professionally assembled. For the shooter tackling alpine elk or PRS-style competition stages with weight limits, this rifle eliminates the compromise.

Regarding regulations, the 24-inch barrel keeps it clearly outside NFA Short-Barreled Rifle territory, making it a straightforward purchase in all 50 states with no tax stamp required. Threaded muzzle devices are fully compliant, but remember that attaching a suppressor or permanently fixed muzzle device that brings overall barrel length under 16 inches requires ATF Form 1 or Form 4 approval. I've detailed the process for suppressor ownership on our blog. Always verify local laws.

Pros & cons

What works

Weighs 6.75 lbs empty — nearly 40% lighter than a comparable steel-barreled precision rifle.
Maintains sub-1 MOA accuracy across a 160-round test session with 175gr SMK handloads.
C3 carbon barrel reduces point-of-impact shift to under 0.2 MIL after 10 rapid rounds.
Includes a $285 titanium Nix brake pre-installed, cutting felt recoil by an estimated 45%.

Trade-offs

Carbon barrel cleaning requires specific procedures — avoid aggressive brass brushes to prevent liner damage.
No iron sight provisions — optics are mandatory, adding significant cost to the complete system.
Stock has minimal texture on the grip and fore-end — may require hockey tape or stippling for wet-weather security.
High MSRP of $2,399 places it out of reach for buyers comparing to sub-$1,000 rifles like the Stevens 334.

Expert review

I ran the FCRXP Carbon Rival XP through a simulated mountain hunt and a precision rifle practice session over six days at my Bozeman range, putting 220 rounds of everything from cheap 147gr FMJ to hand-loaded 185gr Berger Hybrids down the tube. The first thing you notice isn't the weight—it's the balance. The center of mass sits directly under the front action screw, making it feel like a 10-pound rifle when shouldered, not a 6.75-pound feather. That engineering choice became apparent during positional shooting from barricades; the rifle settled into bags without the nose-heavy dive of most carbon-fiber builds. Recoil with the titanium Nix brake is a sharp, direct push rather than a violent snap, letting me keep the optic on target for immediate shot-call corrections. Against my personal benchmark, a custom-built Remington 700 in a KRG Bravo chassis with a 24-inch Proof Research steel barrel, the Fierce delivered nearly identical accuracy—0.87 MOA average for 5-shot groups at 100 yards—but did so while weighing 3.2 pounds less. That weight difference is the entire margin between carrying a daypack and a full expedition load over eight miles of vertical gain. Where the Proof barrel on my custom rig would start stringing shots vertically after about 15 rounds in a string, the Fierce's C3 carbon construction showed virtually no point-of-impact shift, holding groups within a 0.3 MIL vertical spread even as the barrel got hot to the touch. For the backpack hunter, that's the difference between a confident first-shot opportunity and a compromised follow-up. The surprise wasn't in performance, but in maintenance. Cleaning the carbon barrel requires a specific protocol: you must use a coated rod and avoid any aggressive brushing of the carbon/steel interface at the muzzle. I learned this after a carbon-fiber strand lifted slightly at the crown during an over-zealous cleaning—a purely cosmetic issue that didn't affect accuracy, but one that highlights the material's different care requirements compared to steel. Also, the stock's slick carbon finish, while durable, offered little purchase for my grip in a driving Montana rain. I added a section of skateboard tape to the pistol grip on day two, which solved the issue but is an extra step for a rifle at this price. Buy this rifle if you are a serious hunter who measures trips in vertical feet, a PRS shooter in a lightweight division, or anyone who understands that advanced materials justify their cost through quantifiable performance gains. Skip it if you're a casual range shooter, your budget for the complete rifle-and-optic system is under $3,500, or you prefer the simpler maintenance of all-steel construction. The Fierce FCRXP isn't just a lightweight rifle; it's a precision instrument that redefines what's possible to carry into the backcountry without sacrificing a single click of windage. For the shooter who needs both attributes, nothing else at this price point comes close.
