Manufacturer details
In 2010, the US Marine Corps adopted the HK M27 as its new Infantry Automatic Rifle (IAR). The rifle is named for the 1st Marine Division, 2nd Battalion, 7th Regiment, that tested the rifles and IAR (infantry automatic rifle) concept for more than a decade. Replacing the M249 for rifle squads, the M27 was once declared "The most tested weapon in the history of the Marine Corps". The M27 has proven itself again and again, from the test ranges at Twenty Nine Palms to the Global War on Terror - and beyond. With its precision, durability, and reliability, the M27 expanded beyond the initial role of IAR. The M27 is fielded today as an IAR, precision rifle, general infantry rifle, and most recently as a short-barreled upper receiver Reconnaissance Weapons Kit (RWK). Now civilians can own a piece of Marine Corps history with the limited-run HK MR27, a civilian-legal tribute to the M27. The MR27 uses the same HK DNA and offers the battlefield-proven reliability, durability, and precision of a worthy homage to such a proven military rifle.

A note on accuracy. We work hard to keep every listing correct, but specifications, images and compliance details come from many sources and can contain errors or change without notice. Images may show a configuration that is not California-legal. If a detail on this page matters to your decision, call us and we will confirm it against the actual firearm before you order. The compliance information here is general in nature and is not legal advice; California and local laws change, and the configuration described is confirmed at the time of sale. All sales are subject to applicable federal, state and local law and to the buyer's eligibility to purchase.
