Magnum Research BFR .454 Casull 6.5" SS Revolver with Bisley Grips, 6-Round Capacity
Magnum Research
The Magnum Research BFR 45LC/410GA revolver is a true dual-caliber workhorse built for hunters and sport shooters who demand versatility without compromise. This 7.5-inch vent rib model chambers both .45 Long Colt and .410 shotgun shells in the same cylinder, giving you the flexibility to switch loads on the fly—full-power rifle rounds for larger game, or buckshot for close-range defense and pest control. With its brushed stainless steel construction and 6-round capacity, the BFR delivers rugged reliability in a package that handles hard use in the field or at the range.
The Bisley grip frame sets this revolver apart from standard designs, offering a lower hand position and shorter trigger reach that many shooters find more comfortable during extended shooting sessions. The factory black fixed front sight pairs with an adjustable rear sight, letting you dial in your point of aim quickly whether you're shooting .45 LC or .410. At 4.5 pounds and 15 inches overall length, the BFR is substantial enough to manage recoil responsibly but still packable for hunting trips or property defense.
A smooth 3–4 pound trigger pull keeps the action predictable whether you're hunting hogs, deer, or varmints, or pushing brass at the range. The dual-caliber design means one gun handles situations that might otherwise require two, making the BFR a practical choice for overlanders, homesteaders, and serious hunters who value single-gun versatility.

Yes. The BFR's dual-caliber design allows you to load either .45 Long Colt rifle rounds or .410 shotgun shells into the same 6-round cylinder, giving you the flexibility to select the right load for your hunting or shooting situation without changing revolvers.
The vent rib improves your sight picture by raising your line of sight and reducing mirage in bright conditions. The 7.5-inch length also provides better velocity than shorter barrels while remaining maneuverable in field conditions.
The Bisley design positions your hand lower on the frame and shortens the trigger reach, which many shooters find more comfortable and natural for sustained shooting. Combined with the revolver's 4.5-pound weight, it helps manage the recoil of both .45 Long Colt and .410 loads.
The BFR features a factory black fixed front sight and an adjustable rear sight, allowing you to zero the gun for your preferred distance and load.
