Aerospace and defense company ATK (NYSE: ATK) is buying Bushnell Group Holdings Inc. for $985 million in cash.

Bushnell, headquartered in Overland Park, Kan., designs and sells branded sports eyewear. The company’s products include laser rangefinders, trail cameras, riflescopes, binoculars, hunting and shooting accessories along with sun, winter and safety eyewear.

The deal should expand Arlington, Va.-based ATK’s product line to include security ammunition, sporting arms and other accessories. ATK sells shooting equipment, targets, gun-care products, optics and mounting systems for firearms.

In June, the company bought Savage Sports Corp., which added rifles, shotguns and shooting range systems to the company. 

Bushnell is being sold by MidOcean Partners, a middle market private equity firm based in New York. MidOcean acquired the company in August 2007, and made nine add-on acquisitions: Cebe, Gold Tip, Kolpin, Millet, Neo, Night Optics USA, Primos Hunting, Simmons and Ultropics. The firm is also invested in Global Knowledge, South Beach Diet and Water Pik, in which it invested in July. 

Morgan Stanley & Co. LLC (NYSE: MS) and Robert W. Baird & Co. Inc. are acting as Bushnell’s financial advisers. Kirkland & Ellis LLP is providing legal advice to Bushnell. Cravath Swaine & Moore LLP was legal counsel to ATK for the deal.
