Hydra Weaponry—the designer and manufacturer of the modular Marck-15 Hydra Weapon System and Maine’s largest firearm employer—has expanded into a new 20,000-sq.-ft. facility. The addition of a second location significantly increases the company’s production capacity to meet the rising demand for its growing line of Modular Weapon Systems.

“We’re excited to announce this new chapter for Hydra Weaponry,” said Mack Gwinn, III, owner of Hydra Weaponry. “Our growth is a testament to the quality and craftsmanship that our customers have come to expect. As a descendant of Gwinn Firearms, Bushmaster Firearms and Windham Weaponry, we carry a rich legacy, and this new facility will help us continue to raise the bar for firearms manufacturing in the USA.”

The seeds for Hydra Weaponry’s dedication to innovation were planted while Mack Gwinn Jr. served with the U.S. Special Forces in Vietnam. There he dreamed of a more versatile and reliable firearm with which to arm himself and his men. After leaving the military he founded Gwinn Firearms. Its focus was on developing reliable firearms with modular versatility suitable for both the civilian and military markets. The company ultimately became Bushmaster Firearms in the early 1970s.

Then the firm sold. Gwinn, Jr. didn’t lose his passion for firearms, however. He went on to design the .50 Quick Change Barrel for Fabrique Nationale, 75- and 90-round magazines for the AR-15 and the counterpoise AR operating system with Jim Sullivan. His inventions and patents continued until he created the Hydra Carbine—the weapon he dreamed of as a young Special Forces soldier. The company’s Hydra Marck-15 Hydra is based on the AR-15 platform, but it can adapt to multiple calibers without the use of any tools in just under minutes, per caliber.
