Roller-delayed firearms are known for their reliability and performance under the most extreme conditions. Roller-delayed firearms have been proven by special operations troops in the harshest environments on the planet, from the arctic, to deserts, to jungles. Zenith’s roller-delayed firearms are made by MKE using a combination of original tooling, dies, and data, combined with hi-tech production improvements. MKE has over forty years’ experience crafting roller-delayed firearms. When you buy from Zenith, you are purchasing a first quality roller-delayed firearm from an experienced manufacturer who knows exactly what it takes to create uncompromising quality and reliability.


Zenith’s roller-delayed firearms are available in calibers and sizes to suit most tactical situations. From our 9mm NATO Z-5RS to our 7.62 NATO Z-41 Rifle, our firearms platforms offer the operator flexibility from room clearing in challenging urban environments, to intermediate range target engagement in open terrain. The popularity of the designs means there is never a shortage of aftermarket accessories that increase ergonomics and performance. Why settle for an average rifle, when you can have accuracy, reliability, and endurance in one package?


Zenith stands fully behind our products. We have skilled gunsmiths on staff who are able to meet any maintenance need. We offer everything from complete rebuilds to custom work.
