MRI's Big Frame Revolver is truly the biggest, finest revolver on the market today. Entirely manufactured in the US and like the legendary Desert Eagle pistol it is designed as a magnum from the ground up. The BFR is all stainless and has a cut rifled barrel that delivers unmatched accuracy with lead or jacketed bullets. The BFR is the most powerful production single action gun made and with 12 calibers and two frame sizes to choose from you can take everything from grouse to grizzly. Choose your chambering and frame size and have your favorite gun dealer locate one of the BFRs for you.

    I have several thousand rounds through this gun. It is a very well built gun with very tight tolerances. I've owned many SA revolvers and the BFR is without question the finest. With the right load it'll shoot through the same hole at 50 yards.
