25mm Anti-Material Payload Rifle (AMPR-XM109)

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 XM107 against 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

Battelle Weaponeering Study

• Summarized Results: Probability of Target Defeat– Big Bird Radar

• At 800 meters the XM109 required half as many rounds as the XM107.

– BMP-3• At 800 meters the

XM107 required 2 times more rounds than the XM109.
