GMS Plesium

Defense technology is not just about steel, mechanics, and standards. At its heart, it is about the trust that soldiers in the field place in the systems they operate when the pressure is highest.

This is where GMS Plesium comes in.

Rather than developing heavy gun mounts in isolation, the company works closely with operators and listens to their feedback. The result? Every mount reflects conversations with soldiers about what it takes to perform under stress—how a system should handle, how it should hold up, and how it should feel in the hands of those who depend on it. This direct collaboration has enabled the company to refine its products with practical improvements in weight, ergonomics, and durability, establishing it as a leading name in the heavy gun mount space.

CEO Ramon Cabasés says, “Our clients keep coming back because they know we don’t just provide a product; we provide a commitment.”

Quality is at the core of operations. All mounts are manufactured to ISO standards and tested against MIL-STD 810G requirements. These are not just laboratory tests but exercises conducted alongside soldiers themselves. The results are systems that withstand heat, cold, vibration, dust, and impact while remaining easy to maintain in the field. Operators consistently note their robustness and reliability: qualities that translate directly into confidence in high-stakes situations.

The company’s design philosophy is guided by the principles of simplifying and strengthening. By keeping systems straightforward to operate and robust in structure, GMS Plesium ensures that mounts function as extensions of the operator’s body. Each unit is tested repeatedly before delivery, with the goal of making every component 100 percent dependable.

GMS Plesium is also committed to modularity and interoperability. Its product line allows for rapid configuration changes and cross-platform integration, giving armies greater tactical flexibility and, importantly, better resource efficiency, since one system can adapt to multiple missions.

Adaptability has also defined the company’s response to unique client challenges. For example, when a European army approached GMS Plesium for a truck-mounted system with an unusual weapon, the team delivered a working prototype within four weeks. Three months later, more than a hundred units had been manufactured and deployed. The project demonstrated not only technical capability but also the agility and responsiveness that defense partners value.

Being regarded as more than a supplier is central to the company’s identity. GMS Plesium supports clients throughout the entire lifecycle of its products, from design to upgrades and maintenance.

“We like to say that we don’t just sell equipment—we deliver long-term commitment,” says Export Manager Oriol Rubira.

This philosophy has helped the company build long-standing relationships with major names such as UROVESA, the Spanish Army, the Spanish Marines, EINSA, KNDS, MSC Qatar, the Egyptian Army, Cardama, Marine Alutech, SCANIA, Tatra Defense, Heckler & Koch GmbH, FN Herstal UK, Streit Group, or Suncraft International.

With more than 35 years of industry experience combined with the energy of a start-up, GMS Plesium’s trajectory is clear. Its blend of experience, innovation, and hands-on collaboration has enabled the company to build systems trusted by defense forces across the globe—systems proven in environments where trust is everything.

In the end, GMS Plesium is building confidence, one mission at a time.
