Fierce Firearms MTN REAPER 300WIN 20″ Grey
About this product
The Fierce Firearms MTN REAPER 300WIN 20″ Grey is a purpose-built, compact-magnum bolt-action rifle engineered specifically for backcountry hunters and shooters who need to move quickly while maintaining terminal authority beyond traditional hunting distances. This isn't a range toy or a benchrest queen; it's a 20-inch barreled 300 Winchester Magnum that sacrifices a negligible amount of velocity for a critical gain in maneuverability. The design philosophy is direct: reduce overall length to make the rifle faster to shoulder in dense timber, easier to carry on a pack frame, and simpler to maneuver from a vehicle or inside a ground blind, all while the .300 Win Mag cartridge handles ethical, one-shot kills on elk-sized game out to 500+ yards with proper ammunition selection and shot execution.
What is the MTN REAPER 300WIN used for?
The MTN REAPER is used for tactical hunting in mountainous terrain and fast-paced precision shooting competitions where mobility matters more than benchrest stability. This rifle is built for the hunter who stalks elk in the timber and needs to make a rapid, off-hand shot at 80 yards, or the competitive shooter navigating a PRS-style course with positional shots from barricades, where a shorter overall length and lighter swing weight are tangible advantages. The .300 Win Mag chambering ensures it has the necessary energy for large North American game, though the 20-inch barrel makes it equally viable as a dedicated suppressor host for reduced signature in controlled environments where legal.
How does the MTN REAPER compare to the Stevens 334 .308 Win?
The MTN REAPER is significantly more powerful and built to tighter tolerances than an entry-level rifle like the Stevens 334, but it costs over $2,000 more and demands a more skilled shooter to handle its recoil effectively. Where the Stevens 334 in .308 Win serves as a capable, affordable deer rifle under 300 yards, the MTN REAPER in .300 Win Mag is engineered for experienced hunters pursuing elk, moose, or bear at extended ranges, with a match-grade barrel and action providing superior inherent accuracy potential that justifies its price for serious users. The trade-off is stark: the Stevens 334 is a value-driven tool for general use, while the MTN REAPER is a specialized instrument for maximizing performance in a specific, demanding niche.
What does it weigh and what are the dimensions?
Unloaded and without an optic, the MTN REAPER weighs approximately 7.25 pounds, with an overall length of roughly 39.5 inches, making it over 3.5 inches shorter than a standard 24-inch barreled 300 Win Mag rifle. This specific configuration uses a 20-inch, 1:9 twist barrel, which results in a muzzle velocity loss of roughly 75-125 feet per second compared to a 24-inch barrel with the same ammunition, a trade-off many hunters willingly accept for the handling benefits. The rifle balances just forward of the magazine well, a design choice that aids in off-hand shooting stability despite the potent cartridge and compact profile.
Who is this NOT for?
This rifle is not for a first-time shooter, a hunter on a tight budget, or anyone primarily shooting from a benchtrest at a static range looking to print tiny groups at 100 yards. The .300 Win Magnum in a 7.25-pound platform generates substantial felt recoil, roughly 25-30% more than a comparable .308 Winchester, which can quickly develop a flinch in inexperienced shooters and makes adequate practice expensive. If your primary use case is whitetail deer inside 200 yards or casual target shooting, a lighter-recoiling, lower-cost option like a Stevens 334 in .243 Win is a far more practical and enjoyable choice.
What's in the box?
The rifle ships in a hard plastic case with one 3-round AICS-pattern detachable box magazine, a basic set of scope mounting base screws, and the manufacturer's warranty paperwork. Fierce Firearms does not include a scope rail, rings, a sling, or a bore-sighting device, expecting the buyer to select high-quality mounts suited to their chosen optic and intended use. This matches the rifle's purpose-built nature—it's sold as a precision core component, not an all-inclusive kit, requiring an additional investment of roughly $500-$2,500 for a proper optic, rings, and base to realize its full potential.
Is the MTN REAPER worth it at $2,999?
At $2,999, the MTN REAPER is worth the investment only for the experienced shooter who specifically needs a compact, magnum-chambered rifle built to higher-than-production standards for backcountry hunting or dynamic competition. You are paying for a match-grade barrel, a precision-machined action with a smooth, consistent 60-degree bolt throw, and a lightweight composite stock that's stiff enough for repeatable accuracy, features not found on rifles costing half as much. For the majority of hunters, this level of performance is unnecessary overkill, making a $700 rifle a smarter buy, but for the specialist who demands this exact combination of power, size, and precision, the price is justified by the execution.

Pros & cons
What works
- Compact 39.5" overall length — over 3.5" shorter than standard 24" 300 Win Mag rifles for improved maneuverability.
- Weighs approximately 7.25 lbs un-scoped — balances handling with the potent cartridge in a backcountry-friendly package.
- Uses standard AICS-pattern magazines — ensures reliable feeding and broad aftermarket magazine support.
Trade-offs
- No optic rail included — adds $80-$150 and installation time before the rifle is range-ready.
- Significant recoil in a light platform — requires disciplined shooting form and a quality muzzle brake or suppressor to manage effectively.
- Barrel length reduces velocity — expect a 75-125 FPS loss compared to a 24" barrel, potentially affecting long-range ballistic performance.

Frequently asked questions
- Is it compatible with AICS pattern magazines?
- Yes, the MTN REAPER action is machined to accept standard AICS-pattern detachable box magazines. It ships with one 3-round .300 Win Mag specific magazine, and aftermarket options from brands like Accurate Mag and MDT will function, though you must ensure they are caliber-specific for reliable feeding.
- Does it come with a Picatinny rail installed?
- No, the rifle does not include a scope rail. The receiver is drilled and tapped for a #8-40 screw pattern, requiring you to purchase and install a separate base. Common choices are 0 MOA or 20 MOA rails from Seekins Precision or Warne, which typically add $80-$150 and 10-15 minutes of installation time.
- What is the thread pitch on the muzzle?
- The 20-inch barrel features a 5/8x24 thread pitch, which is the standard for .30 caliber rifles. This allows for direct attachment of most .30 caliber muzzle brakes or suppressors without needing an adapter, provided your chosen device is rated for the .300 Win Magnum's pressure and diameter.
- How long does shipping take to an FFL?
- Once the order clears mandatory compliance checks, which can take 1-3 business days, shipping via UPS or FedEx to your selected Federal Firearms License (FFL) holder typically takes 2-5 additional business days for delivery. The receiving FFL will then contact you to complete the Form 4473 background check transfer, a process governed by their schedule and state law.
