Key Features
- 20-Inch Barrel: This shorter barrel keeps the rifle compact for tight cover and climbing steep terrain, while still delivering the velocity needed for ethical shots on big game at extended ranges.
- Grey Finish: The non-reflective grey coating reduces glare in the field, helping you stay concealed from wary game during dawn and dusk hunts.
- .300 Win Mag Chambering: The classic magnum cartridge gives you flat trajectories and hard-hitting energy for elk, bear, and long-range mule deer, with plenty of factory ammo options.
- Lightweight Build: At around 6.5 lbs, this rifle cuts down on pack weight without sacrificing the strength needed for repeated use in backcountry conditions.
- Bolt-Action Reliability: Fierce Firearms’ action is known for smooth cycling and consistent lock-up, which translates to repeatable accuracy shot after shot.
Who It’s For
The MTN REAPER is for the hunter who spends more time hiking than sitting in a blind. If you’re after elk in the Rockies, chasing blacktails in the Coast Range, or packing into the Selway-Bitterroot for mule deer, this rifle is built to carry all day and shoot when it counts. It’s also a solid choice for the precision-minded shooter who wants a production rifle that feels custom.
Pros & Cons
- Pros: Light enough for mountain hunts; accurate out of the box; short barrel handles well in brush; Fierce Firearms has a solid reputation for fit and finish.
- Cons: The 20-inch barrel does reduce muzzle velocity by about 100-150 fps compared to a 24-inch tube, which may matter if you’re shooting past 600 yards. Also, the grey finish can show scratches more than a matte black or camo pattern.

FAQ
What is the barrel twist rate on the Fierce Firearms MTN REAPER 300WIN 20″ Grey?
Per Fierce Firearms specs, the twist rate is 1:10 inches, which stabilizes most factory .300 Win Mag bullets from 150 to 200 grains.
Does this rifle come with a scope or rings?
No, the MTN REAPER is sold as a barreled action only. You’ll need to mount your own scope and rings. Fierce recommends Talley or Leupold rings for a solid fit.
Is the grey finish a Cerakote?
Yes, according to Fierce Firearms, the grey finish is a Cerakote coating that resists corrosion and scratches from field use.
How does the 20-inch barrel affect accuracy?
In my experience, the shorter barrel doesn’t hurt accuracy—it’s still sub-MOA capable with good ammo. You trade a bit of velocity for better handling in tight spots.
Can I use this rifle for elk hunting?
Absolutely. The .300 Win Mag with a 20-inch barrel is a proven elk cartridge. Keep shots inside 500 yards and you’re golden.
