Nammo noted that it has taken over the ownership position in MAC after the US Government reviewed and approved the transaction.

MAC will trade under the Nammo Small and Medium Caliber Ammunition division and will play a key role in Nammo’s US growth plan.

Nammo Small and Medium Caliber Ammunition executive vice-president Reijo Bragberg said: “Through this decision, we are now establishing Nammo and MAC as frontrunners in development of lightweight technologies, which are of great importance for our defence customers.”
