Origins and Early History of the USMC M27 Infantry Automatic Rifle
The M27 IAR, based on the HK416, was developed to offer a lighter, more accurate alternative to the M249 SAW for USMC infantry. Despite initial resistance and accessory issues, its improved accuracy at range and easier maintenance proved beneficial in combat environments like Afghanistan. Key differences from the HK416 include a heavier barrel and specific USMC additions.
