Facts & Claims

Facts

  • A known commodity: The Barrett M107 is combat proven and User respected—the XM109 possesses much of the same architecture as the M107
  • Ammunition Availability: The 25mm XM109 will use the self-same 25mm armor-piercing ammunition as the Objective Crew-Served Weapon (XM307)

Claims

  • The 25mm XM109 offers significantly greater lethality than the .50 caliber XM107against C4I SAR targets
    • Near term: Penetration potential from optimizing warhead promises over 1 ½ -inches of RHA at 1200 meters and beyond
    • Long Term: Optimized AP ammunition offers 2 + inches of HHA
system characteristics
SYSTEM CHARACTERISTICS
  • WEAPON SYSTEM HAS RAPID CONVERSION CAPABILITY FROM M107 TO XM109
  • XM109 & M107 HAVE 70% COMMONALITY
  • MAJORITY OF REPLACEMENT PARTS ARE CURRENTLY IN SUPPLY SYSTEM
  • WEAPON SYSTEM IS 10 INCHES SHORTER THAN M107
  • CAPABLE OF DEFEATING MOST LIGHT ARMOR AND MATERIEL TARGETS OUT TO 2000 METERS
