Slovenian company Arex might sound like a new name in the firearms industry but this could not be further from the truth. Arex is a renowned company that has already earned its good name in the defense industry. The company has been creating and manufacturing defense products for more than 20 years.


















Employee numbers have been continuously increasing since the company was started. Arex employs mostly engineering professionals. Almost 70% are workers with education levels IV and V, while the percentage of employees with lower levels is less than 5%. Employees with education levels VI and VII, that take care of the development and managing other processes, is 25%.

Most employees are below 40 years old.That proves Arex is future-oriented and by all age groups being strongly represented the company ensures the dynamics of production processes and customer relations on the one hand, as well as expertise and prudence on the other.The knowledge and experience of senior generations are passed on to younger colleagues.


Highly qualified and motivated employees solve customers’ development, design, and product testing problems daily. As a niche manufacturer, Arex is active within several branches, but mostly in the defense industries, where we are becoming more and more established as solvers of unsolvable problems.


The company has accumulated extensive knowledge and experience in the field of CNC machining and tooling, part of it resulting directly from manufacturing key firearms components for some of the major European manufacturers. We acquired and set up our own barrel manufacturing plant in 2012 which was the last missing piece necessary for the self-sufficient design and manufacture of an original firearm. 

REX zero 1 is definitely the first pistol that is in-house designed as well as manufactured, but we have been developing and making firearms parts since 2005.


The REX zero 1 pistol does not claim to be a revolutionary breakthrough but you will find it represents a definitive evolutionary step in modern handgun design and manufacturing. We have achieved improvements over some of the most popular designs, eliminating their weaknesses and enhancing their advantages by applying our expertise and state-of-the-art CAD/CAM processes. The result is a best-in-class defensive pistol that boasts extreme reliability and accuracy along with a competitive price.
