Diemaco was a Canadian defence company based in Kitchener, Ontario, that manufactured the C7 family of rifles under a licence from Colt.
History
The company was formed in 1974 under Devtek Corporation,[1] effectively replacing the arms supply from government owned Canadian Arsenal Limited.
In 2000, it was acquired by Héroux-Devtek Inc.[2][3]
On May 20, 2005, it was acquired by Colt Defense for $18.2 million.[4] As a result, Héroux-Devtek revamped the Aerospace and Defense division to the Aerospace division.[5]
