Founded in the late 1950s, NAACO aimed to supply high-quality sporting and hunting firearms to the Canadian and international markets. The company operated out of facilities in East York and Scarborough, Ontario. Its leadership included John R. Cavanaugh as president and Major-General Chris Vokes on the board of directors.

NAACO ceased operations around 1962, possibly due to financial difficulties and alleged involvement in international arms dealings.

NAACO's catalog included a wide array of bolt-action rifles and pump-action shotguns, many under the "Grizzly" and "Mallard" brand names.
