Hydra Weaponry, Maine’s largest firearms employer, designers, and manufacturers of the truly modular MARCK-15 Hydra® Weapon System, introduces the new Hydra MARCK-15 H21 rifle built to use GLOCK-style 10mm magazines. This will become every GLOCK 20 and GLOCK 29 pistol owner’s new rifle partner. With the rise of the popularity of the 10mm again, the Hydra H21 rifle makes a powerful deer hunting tool in most states with the 10mm round for its high-velocity and flat shooting capability.

The 10mm cartridge was designed in response to the cataclysmic 1986 FBI Miami shootout in which FBI agents using 9mm caliber pistols were seriously outperformed. The caliber was later decommissioned as it was found to be too recoil-heavy for trainees and the 10mm pistol grips were too large for smaller-handed agents. The .40 S&W was developed and replaced the 10mm, although it is still used by many law enforcement officers for its greater firepower and flat shooting. Handgun hunters have increasingly switched out to 10mm firearms, including the full-sized GLOCK 20 10mm pistol. This makes the Hydra H21 MARCK-15 modular rifle in 10mm a perfect pairing for those who already carry the GLOCK 20 or compact GLOCK 29, or those looking to utilize a 10mm AR deer hunting platform (check state and local laws for AR and caliber allowances for deer/and or any other hunting regulations).

The Hydra Weaponry team designed a Hydra modular lower receiver with a 10mm H21 magazine well. With the H21 mag well as the starting point, Hydra included the Hydra Quick Change Barrel Upper Receiver (QCB-D) along with a Hydra 16-inch 10mm blowback barrel, a 10mm blowback bolt, and a durable B5 Systems stock and pistol grip.

Owners of the new Hydra MARCK-15 10mm H21 Modular Rifle can use this as the base to expand caliber capabilities through Hydra Weaponry’s growing magazine well and caliber conversion kits. Easy to change out, even in the field, the rifle requires no tools to convert to another caliber with the most the user will ever need to change out is the barrel, bolt, bolt carrier, and the magazine well to the new caliber.

“A modular concept rifle is the most cost-effective system to purchase when money is an issue but you need multiple calibers to accomplish different tasks. That is why our Hydra MARCK-15 Modular Rifles offer the best in the field for quality and accuracy while being kind to your wallet. Now, with our sale in process, it’s the time to get your hands on a base model and as many conversions as possible!” Mack Gwinn III, CEO of Hydra Weaponry, said.

The Hydra MARCK-15 H21 10mm Modular Rifle weighs 10 lbs. and measures 21” x 3” x 7” in a black finish. Inserts for the handguard include MLOK, KeyMOD, and Picatinny. MSRP $1,400 to $1,538.00. Order online and pick up at your local dealer.
