Magnum Research BFR

The Magnum Research BFR is a single-action revolver manufactured by Magnum Research. It is made from stainless steel and is manufactured in a variety of heavy calibers, such as .500 S&W Magnum, including some traditional rifle cartridges, such as the .30-30 and .45-70/.450 Marlin. The name "BFR" officially is an acronym for "Big Frame Revolver" or "Big Finest Revolver".

Available Cartridges
The BFR comes in two basic models, one with a long cylinder for larger rifle cartridges, and one with a more traditional revolver cylinder length (called "short" by Magnum Research). Note that some models that use identical bores such as the .45/70 and .450 Marlin can be made with two cylinders for the same gun.

Magnum Research makes these guns in custom calibers and discourages the use of most rimless cartridges in their revolvers due to mechanical issues. The BFR can be customized for the .50 Beowulf cartridge. These revolvers were originally made by DMAX in Springfield, South Dakota until Magnum Research bought them out.
