Hermon, Maine (June 2024) – Hydra Weaponry, Maine’s largest firearms employer, designers, and manufacturers of the truly modular MARCK-15 Hydra® Weapon System, believe ownership of an AR-style firearm should not be denied to any lawful and legal American, including Californians. In response to all the compliance regulations California has dumped on its citizens, Hydra Weaponry offers a Cali-Compliant MARCK-15 Modular Rifle.

The Cali-Compliant rifle is set up as a 5.56 x 45 on a Hydra® Modular Lower Receiver with an AR mag well. The compliant 10-round AR magazine is fixed. The upper receiver is Hydra’s Quick-Change Barrel upper (QCB-D) with a 16-inch 5.56 bull-nose barrel with no gas port. The Hydra Modified Bolt Carrier with a 5.56 bolt and firing pin and a Hydra D-Fender D-Ring are all part of this unique modular system that serves as the base for additional multiple caliber conversions. The Cali-Compliant MARCK-15 rifle is built on a B5 Systems pistol-grip stock.

“Our Cali-Compliant MARCK-15 rifle features the same key elements of modularity, accuracy, and consistent performance as any of our other MARCK-15 models, but with all the state regulations of California built in,” Mack Gwinn, CEO of Hydra Weaponry added.
