The company said that the contracts comprise of: an award for MUSA's Mk43 Electronic Boresight System (EBS), which is utilised within a weapon system in the precision boresighting of cannons and can be operated by a single person, in support of a US Air Force weapons programme; an award for MUSA's EBS in support of a valuable commercial partner's weapons programmes; an award for MUSA's EBS in support of a US Navy weapons programme; an award for M2 and M3 .50" calibre Aircraft Barrels in support of US weapons programmes, this will initiate production of the .50" calibre barrel production line, which has a potential capacity of over 1,000 barrels per month and an award for rifle components in support of one of MUSA's valuable commercial partners for civilian rifle products.
