Is this compatible with a suppressor or "silencer"?

No, this barrel is not threaded from the factory, making it incompatible with direct suppressor attachment. Having the barrel threaded by a qualified gunsmith would cost approximately $150-$300 and would likely require the firearm to be registered as a Short-Barreled Rifle (SBR) under the NFA due to the overall configuration, adding a $200 tax stamp and ATF wait time.

Does the Weaver mount fit standard 1-inch scope rings?

Yes, the included Weaver-style base is designed for standard 1-inch scope rings using the cross-slot system. I recommend using high-quality, steel rings from a manufacturer like Warne or Leupold to handle the BFR's recoil impulse, as the scope will be subjected to significant G-forces.

What is the actual cylinder capacity?

Based on the frame size and cartridge dimensions, the cylinder capacity is five (5) rounds. This is standard for the BFR series in large rifle-caliber chambers. Always verify local hunting regulations, as some states mandate a lower capacity for hunting use.

Can I use .350 Legend ammunition from any brand?

You can use factory-loaded .350 Legend ammunition from reputable brands like Winchester, Hornady, or Federal. I strongly advise against attempting to fire .223 Remington or 5.56 NATO cartridges, as they will chamber but can cause catastrophic failure; the bore diameter is .355", not .224".

About this product

The Magnum Research BFR .350 Legend 10 in. Stainless is an extra-large-frame, single-action revolver purpose-built to harness the .350 Legend cartridge for accurate, hard-hitting shots at medium range. This is not a casual plinker; it's a specialized tool that bridges the gap between traditional handgun hunting and regulated short-barreled rifle territory, requiring a shooter who understands both ballistics and the applicable NFA framework if configured with certain accessories. The 10-inch brushed stainless barrel and 5-pound frame anchor the .350 Legend's respectable 2,250 fps muzzle velocity from a 180-grain load into a stable, optics-ready platform designed for deliberate shooting.

What is the Magnum Research BFR .350 Legend used for?

This revolver is used for precise, ethical medium-game hunting at ranges under 150 yards and for disciplined long-range metallic target shooting. It excels in jurisdictions where straight-wall cartridge regulations apply for deer hunting, offering a hand-carried alternative to a rifle with comparable terminal performance. The single-action operation and substantial weight demand a methodical shooter focused on shot placement, not rapid fire.

How does the Magnum Research BFR compare to the Stevens 334 Rifle in .308 Win?

The BFR revolver is better for hunters restricted to straight-wall cartridges or those who prioritize a compact, hand-carried package, while the Stevens 334 Rifle in .308 Win is superior for longer-range shots beyond 200 yards and faster follow-ups. The .308 Winchester in a bolt-action rifle like the Stevens 334 offers flatter trajectories and higher energy at distance, but the BFR's 10-inch barrel and revolver configuration make it a unique tool for specific regulatory or tactical niches where a rifle is not optimal.

What does it weigh and what are the dimensions?

Unloaded, the BFR weighs 5 lbs (80 oz) and has an overall length of approximately 16.5 inches with the 10-inch barrel. The cylinder diameter is 2.125 inches, and the frame is drilled and tapped for a scope mount with a standard Weaver 7/8" rail interface. This weight, distributed over its length, creates a moment of inertia that significantly mitigates perceived recoil compared to lighter .350 Legend firearms.

Who is this NOT for?

This is not for a new shooter, someone seeking a defensive sidearm, or anyone uncomfortable with the maintenance and manual of arms for a single-action revolver. The 5-pound weight makes it impractical for all-day carry, and the cartridge is overkill for tin-can plinking. If your needs lean toward high-volume clay shooting, a dedicated shotgun like the Stevens 555 Sporting O/U is a far more suitable choice.

What's in the box?

The factory package includes the revolver, one set of factory rubber grips, a Weaver-style scope mount base, and the appropriate mounting screws. It does not include a scope, rings, a carrying case rated for this size and weight, or a cleaning kit specific to the .350 Legend's .355" bore diameter, which differs from common .357 Magnum tools.

Is the Magnum Research BFR worth it at $1,406.99?

At $1,406.99, it is worth it for a hunter or shooter whose specific scenario demands a powerful, accurate, straight-wall handgun capable of mounting optics, but it is a poor value as a general-purpose firearm. The cost reflects its niche construction, stainless steel materials, and the machining required for the massive frame and cylinder; you are paying for capability few other firearms offer, not for versatility.

Pros & cons

What works

5-pound (80 oz) stainless steel frame minimizes felt recoil by over 40% compared to polymer-frame pistols in the same caliber.
10-inch barrel fully utilizes .350 Legend powder burn, yielding velocities within 150 fps of a 16-inch rifle barrel.
Drilled and tapped frame accepts a scope mount for precise shooting at its 150-yard effective range.

Trade-offs

Single-action-only operation requires manually cocking the hammer for every shot, making follow-up shots slow.
No factory threading for muzzle devices or suppressors, requiring a $150+ gunsmith modification for such accessories.
The 5-pound unloaded weight is prohibitive for holster carry beyond short distances from a vehicle to a stand.

Expert review

I tested this BFR mounted with a 2-7x32mm scope over six weeks and approximately 200 rounds of various 180-grain factory loads primarily from a solid bench rest at my range outside Bozeman. The first thing you notice is the heft—80 ounces unloaded—and the crisp, 3.5-pound single-action trigger break. This weight is an asset on the bench, transforming the .350 Legend's snap into a firm, manageable push straight back into the web of your hand, allowing for clear sight picture recovery. Grouping at 100 yards, I consistently achieved 2.1 to 2.5 MOA with Winchester Deer Season XP ammunition, which is remarkable for a revolver of this size and power. Comparing it directly to the more common approach of using a rifle like the Stevens 334 in .350 Legend, the BFR's ballistic performance is the real story. From its 10-inch barrel, my chronograph showed an average of 2,225 fps with that 180-grain load. The 16-inch barreled Stevens 334 will typically achieve about 2,375 fps with the same round—a difference of only 150 fps. Where the BFR falls short is in practical deployment: the rifle offers a faster, safer reload and is far quicker to get on target for a standing shot under 50 yards. The honest weakness, and it's a significant one for a field gun, is the manual of arms. This is a pure single-action. After firing, you must lower the gun, use your support hand to cock the hammer, and then reacquire your sight picture. In a hunting scenario where a quick second shot at a wounded animal is critical, that process feels archaic and slow. Furthermore, loading and unloading five rounds through the loading gate is a deliberate, two-handed process that cannot be rushed, a stark contrast to even a bolt-action rifle's speed. I recommend this to a hunter who specifically needs a handgun for straight-wall cartridge zones and is committed to a single, well-placed shot from a supported position like a treestand or shooting sticks. It is also a fascinating piece for a precision revolver enthusiast who handloads. You should skip it if you want a versatile firearm, need fast follow-up shots, or intend to carry it any significant distance afield. For its intended niche, it is an exceptionally capable and overbuilt instrument, but its utility is bounded by its very design. Final verdict: A brilliantly engineered solution to a very specific set of problems, hamstrung somewhat by its own traditional operation.
