Magnum Research, Inc. (MRI) was an American privately held corporation based in Fridley, Minnesota which manufactured and distributed firearms.

The majority owners, Jim Skildum (President and CEO) and John Risdall (Chairman, COO), had been with the company since its founding in 1979.

In June 2010 Magnum Research, in financial difficulties, was sold to Kahr Arms, an American-based producer of compact pistols.

Since 2009 the Desert Eagle Pistol has been exclusively produced in the USA only, at MRI’s Pillager, Minnesota facility.

[5][7][8][9] MRI offered custom gunsmithing services and had a line of guns that were coated with titanium nitride in artful patterns and designs.
