About this product
The Ironclad Armory Fierce Firearms Carbon Rival XP .300 PRC 20'' Bolt-Action Rifle is a precision-oriented SBR-configured rifle built for long-range engagement in compact terrain. This package combines a hand-lapped, match-grade C3 carbon fiber barrel with a stainless steel Fierce Dual-Lug action and adjustable carbon-fiber stock, delivered at a bare weight of 6.50 lbs. Its 20-inch barrel length and titanium muzzle brake are engineered for suppressor-ready duty and controlled recoil management in the .300 PRC chambering.
What is the Ironclad Armory Fierce Firearms Carbon Rival XP used for?
This rifle is engineered for suppressed long-range engagement in terrain where a full-length barrel is impractical. Its 20-inch barrel, combined with the aggressive porting of the included titanium brake, is designed for fast follow-up shots while maintaining the 1:9" twist stability the .300 PRC demands for heavy, high-BC projectiles. The adjustable comb and vertical palm-swell grip allow for a custom cheek weld and trigger reach, which is critical when shooting from unconventional positions like a vehicle window or steep incline. This isn't a plinker; it's a tool for disciplined shooters who need first-round precision at 800+ yards from a compact platform.
How does the Fierce Firearms Carbon Rival XP compare to the Stevens 334 Rifle in .308 Win?
The Carbon Rival XP delivers superior long-range ballistics and custom-grade components at a significantly higher price point than the utilitarian Stevens 334. Ballistically, the .300 PRC firing from this 20-inch barrel carries more energy at 1,000 yards than a .308 Win does at 600 yards, making the Rival XP better for extreme-distance ethical hunting and target shooting. Mechanically, it uses a proprietary Dual-Lug action with a 70-degree bolt throw versus the Stevens' 90-degree Sako-style action, offering faster cycling. However, the Stevens 334 is the better choice for budget-conscious shooters or those who prioritize cheap, abundant .308 Winchester ammunition over long-range premium performance; you can outfit yourself with a Stevens 334 and a quality optic for less than the $2,399 base cost of the bare Rival XP.

What does it weigh and what are the dimensions?
The rifle weighs 6.50 lbs (approximately 2,948 grams) bare, with an overall length of approximately 40.5 inches based on a 20-inch barrel and standard length of pull. The hand-lapped barrel has a 1:9-inch twist rate and is threaded 5/8"-24 TPI at the muzzle for direct attachment of the factory titanium brake or most .30-caliber suppressors. The stock features 1.5 inches of adjustable comb height travel and an integral 6-inch Picatinny rail section for bipod mounting.
Who is this NOT for?
This rifle is not for the first-time shooter or anyone seeking a low-recoil, low-cost range toy. The .300 PRC is an expensive round to feed, with factory match ammunition costing over $4.00 per round, and its recoil impulse is substantial even with the excellent factory brake. It is also not ideal for dense brush hunting where shots are under 200 yards; the cartridge is overkill, and the 20-inch barrel offers no advantage over lighter, shorter cartridges. Finally, due to its 20-inch barrel, in some jurisdictions this configuration may be considered a "Short-Barreled Rifle" (SBR) under the National Firearms Act, requiring a tax stamp and registration; always verify your local NFA and state regulations before purchase.
What's in the box?
You receive the complete rifle, the installed Trigger Tech Primary ProCurve trigger, the installed titanium Nix Side Port muzzle brake, and one drop-box magazine with a 3+1 capacity. The box does not include scope mounting rings, a bipod, or any thread protectors beyond the installed brake. Ironclad Armory ships all firearms in a TSA-approved lockable hard case with foam cutouts, which typically arrives at the dealer within 7-10 business days for online orders.
Is the Fierce Firearms Carbon Rival XP worth it at $2,399?
Yes, if your use case demands a custom-grade, lightweight, and suppressor-ready long-range rifle in a powerful magnum cartridge. The $2,399 price is justified by the proprietary C3 carbon-wrapped barrel and fully adjustable carbon-fiber stock, components usually found on rifles costing $1,000 more. The cost becomes harder to justify if you will not utilize the rifle's maximum effective range or if you primarily shoot from a bench at a static range; a heavier steel-barreled rifle in 6.5 Creedmoor will offer similar precision for less money with drastically lower ammunition costs. This is an investment for a specific, high-performance niche.

Pros & cons
What works
- Weighs 6.50 lbs (2,948g) bare — over 2 lbs lighter than most steel-barreled .300 PRC rifles.
- 70-degree bolt throw shortens cycling time by ~30% compared to a standard 90-degree action.
- Fully adjustable carbon-fiber stock with 1.5 inches of comb height travel for perfect optic alignment.
- Includes premium titanium muzzle brake that reduces felt recoil by an estimated 40-50%.
Trade-offs
- Proprietary magazine system incompatible with common AICS patterns — replacements cost $65+ and can be hard to find.
- 20-inch barrel length may constitute an NFA-regulated Short-Barreled Rifle (SBR) in some jurisdictions, requiring a $200 tax stamp and ATF paperwork.
- No thread protector included — the muzzle is only protected by the brake, risking thread damage if removed for suppressor use without a dedicated protector.
- .300 PRC ammunition is expensive, with quality match rounds starting at $4.00 per shot, making sustained practice costly.

Frequently asked questions
- Is the muzzle threaded for a suppressor?
- Yes. The 20-inch match-grade barrel is threaded 5/8"-24 TPI, which is the standard thread pitch for .30 caliber suppressors. The included titanium Nix brake acts as a thread protector but is easily removed with a ¾" crowfoot wrench for direct suppressor mounting.
- Does this work with AICS pattern magazines?
- No, it uses a proprietary drop-box magazine system. The rifle ships with one 3-round polymer magazine, and while the footprint is similar, standard AICS 300 PRC magazines from brands like Accurate Mag or MDT will not seat correctly in the Rival's bottom metal. You must source replacement magazines directly from Fierce Firearms.
- Can the trigger pull weight be adjusted?
- Yes. The Trigger Tech Primary ProCurve trigger is user-adjustable for pull weight from approximately 1.5 pounds to 4 pounds using a supplied hex key. The adjustment is performed via a single set screw accessible through the trigger guard; no disassembly of the action is required.
- How long does shipping to an FFL take?
- Ironclad Armory processes and ships all firearm orders within 1-2 business days. Transit time via FedEx Ground is typically 3-7 business days to your selected FFL dealer, assuming no local regulatory delays. You will receive tracking information via email once the package is scanned by the carrier.
