Sales of Colt's modern sports rifles and handguns fell 30 percent last year and cash dwindled to $11.1 million by May 22, according to regulatory filings.
Colt Defense, whose M1911 was the primary sidearm for the U.S. military for most of last century, missed a $10.9 million payment last month to holders of $250 million in its senior bonds.
The current management team led by President and CEO Dennis Veilleux will remain in place throughout the process which is expected to be completed within 60 to 90 days, Colt said.
Perella Weinberg Partners L.P. served as financial adviser to the company, while Mackinac Partners LLC served as the restructuring adviser.
