The Fierce Carbon Rival XP .300 Win Mag 22″ 3+1 is a production-ready hunting rifle built around a lightweight C3 carbon fiber barrel.

Key Features

• Precision-machined stainless dual-lug action — Why it matters: Tight raceways and consistent lockup reduce shot-to-shot variance, critical for first-round cold-bore hits on game.
• Lightweight C3 carbon fiber barrel (22″) — Why it matters: Saves nearly 1 lb over a steel barrel of the same contour, letting you carry more ammo or glass without fatigue on steep climbs.
• Adjustable comb stock with vertical palm swell — Why it matters: Lets you dial cheek height for perfect eye alignment with your scope, reducing parallax error and improving repeatability.
• Drop-box magazine (3+1 capacity) — Why it matters: Reliable feeding in cold, wet conditions; the hinged floorplate lets you clear the chamber without cycling through rounds.
• Sub-MOA accuracy guarantee — Why it matters: Fierce test-fires each rifle and guarantees 0.75 MOA or better with match ammo, so you know your rifle is capable before you pull the trigger.

Who It’s For

This rifle is built for the backcountry hunter who values weight savings without sacrificing terminal performance. If you’re chasing elk, moose, or bear at ranges out to 500 yards and need a rifle that balances carry weight with enough muzzle energy to cleanly take large game, the Carbon Rival XP fits that niche. It’s also a solid choice for the precision-minded shooter who wants a lightweight platform for steel or competition.

Pros & Cons

• Pro: Sub-7 lb weight with a 22″ barrel makes it one of the lightest production .300 Win Mags available.
• Pro: Adjustable comb stock allows precise cheek weld without aftermarket modifications.
• Pro: Sub-MOA guarantee backed by factory test targets.
• Con: The lightweight barrel profile heats up faster during rapid strings — not ideal for high-volume range sessions or competition stages with 10+ rounds in quick succession.

FAQ

What is the barrel twist rate on the Fierce Carbon Rival XP .300 Win Mag?

The barrel has a 1:10″ twist rate, which stabilizes typical .300 Win Mag bullet weights from 165 to 200 grains.

Is the stock fully adjustable for length of pull?

The stock offers an adjustable comb height but does not have an adjustable length of pull. You can add aftermarket spacers if needed.

Does the rifle come with a scope or bases?

No, it ships without optics or scope bases. The receiver is drilled and tapped for standard Remington 700 footprint bases.

Can I use this rifle for long-range target shooting?

Yes, the sub-MOA guarantee and 22″ barrel make it capable for steel out to 800 yards, but the lightweight profile heats up faster than a heavy barrel for extended strings.

What is the magazine capacity?

3+1 — three rounds in the drop-box magazine plus one in the chamber.
