The HK MR27 Tribute Rifle honors the Marine Corps' adoption of the M27 Infantry Automatic Rifle (IAR), a testament to its reliability, durability, and precision. Named after the 1st Marine Division, 2nd Battalion, 7th Regiment, this rifle fills the role traditionally held by the M249 SAW, offering lighter weight and maneuverability with magazine compatibility across the inventory. The MR27 is a semi-automatic version of the battle-proven M27 IAR and is available in a limited run of only 1,000 units, with 500 "Deployment Kits" featuring field-ready accessories such as ACOG/RMR optics, a Blue Force Gear sling, and Magpul magazines. The renowned HK gas piston operating system ensures unparalleled reliability, while the ambidextrous safety enhances versatile handling. This tribute rifle captures the essence of the USMC M27, delivering a collector-worthy homage with battlefield-proven performance.
