| [American Rifleman] While the MP5, HK33 and G3 are still very effective platforms, firearms have gained innovations over the past half century that don’t easily fit within the constraints of these legacy designs. Modern manufacturing techniques mean that machined billet aluminum alloy is lighter and more affordable than steel stampings. Modularity can be built-in, rather than requiring some type of adapting interface for mounting optics and other accessories, allowing a firearm to be tailor fit to the shooter. The market is dominated by certain patterns of furniture, magazines and fire control components, meaning that compatibility with these formats allows for the end user to easily upgrade and customize their own firearms. Zenith Firearms has attempted to offer the best of both worlds—a traditional roller-delayed blowback operating system in a firearm with the latest 21st century features with its Modern Roller-Delayed System (MRDS). |
