The fierce fcrxp300wsm20bf cb rivlxp 300wsm 20 blkf is a production-ready precision rifle that delivers a verified 1/2 MOA accuracy guarantee straight from the factory. Built around a stainless steel Fierce Dual-Lug action with a 70-degree bolt throw and TriggerTech Primary ProCurve adjustable trigger, this rig mates a C3 carbon fiber barrel (match-grade, hand-lapped liner, Matrix finish) to an adjustable-comb carbon stock with vertical palm swell. A Titanium muzzle brake, integral Picatinny bipod rail, and drop-box magazine round out a package that skips the custom shop wait without skimping on precision.

Key Features
- C3 Carbon Fiber Barrel with Matrix Finish — The hand-lapped match-grade liner and Matrix surface treatment reduce heat mirage and stringing during long strings of fire. Why it matters: you get consistent sub-MOA groups shot after shot, even as the barrel warms.
- Adjustable Comb Stock with Drop-Box Magazine — The high negative comb cheekpiece adjusts for cheek weld height, while the drop-box magazine feeds 300 WSM reliably. Why it matters: you can dial in a perfect cheek-to-stock alignment for any optic height, and the magazine feeds without binding under recoil.
- TriggerTech Primary ProCurve Adjustable Trigger — This trigger breaks clean with zero creep, adjustable from 1.0 to 3.5 lbs. Why it matters: a crisp predictable break eliminates trigger-induced error, critical for ringing steel at 800+ yards.
- Integral Picatinny Rail for Bipod — The fore-end includes a machined-in Pic rail for direct bipod attachment without aftermarket adapters. Why it matters: a rock-solid bipod interface keeps the gun stable on barricades or prone, no wobble.
- Solid Carbon Bedding System — The action is bedded directly into the carbon stock using a proprietary composite system. Why it matters: eliminates action flex and maintains zero consistency across temperature and humidity shifts.
Who It’s For
This rifle is built for the long-range shooter who demands 1/2 MOA precision out of the box but doesn’t want to wait 18 months for a custom build. Hunters chasing elk or mule deer in open country will appreciate the 20-inch carbon barrel’s weight savings and the Titanium brake’s recoil reduction. Competitive PRS shooters running the 300 WSM will find the drop-box magazine and adjustable comb stock speed up stage transitions without sacrificing accuracy.
Pros and Cons
- Pro: Factory-guaranteed 1/2 MOA accuracy — verified with match ammo, not a marketing claim.
- Pro: Lightweight at ~7.2 lbs (per manufacturer specs) — easy to carry all day in the field.
- Pro: TriggerTech trigger is adjustable down to 1.0 lb — crisp and repeatable.
- Con: The 20-inch barrel in 300 WSM loses about 100–150 fps compared to a 24-inch tube — a trade-off for compactness and weight. If you need every fps for extreme long-range, consider the 24-inch barrel option.

FAQ
What is the barrel twist rate on the Fierce Carbon Rival XP in 300 WSM?
The factory twist rate is 1:9 inches, optimized for 150–200 grain bullets commonly used in 300 WSM for long-range hunting and target work. Per Fierce Firearms specs, this twist stabilizes heavy-for-caliber projectiles like the 200-grain ELD-X.
Does the rifle come with a scope base or rings?
No, the receiver is drilled and tapped for a 20 MOA Picatinny rail (sold separately). You’ll need to mount your own scope base and rings. The integral bipod rail on the fore-end is pre-installed.
Can the adjustable comb be swapped for a fixed comb?
Yes, the cheekpiece is removable. If you prefer a fixed comb, you can take it off entirely or replace it with a low-profile pad (not included). The stock is designed for modularity.
Is the Titanium muzzle brake removable?
Yes, it’s threaded on (5/8×24 pattern) and can be removed or replaced with a suppressor-compatible muzzle device. Note: the brake is not suppressor-ready; check thread pitch before mounting a can.
