TRANSCRIPT
7.62x 51 SSP Subsonic Penetrator
Provides superior accuracy, stealth and penetration capability
McLean, VA USA
Typical Problems with Subsonic Ammo
• Significantly limited effective range, often less than 200 yards• Limited penetration capability, due to reduced velocity and terminal
energy• Weapon jamming/ failure to cycle, due to lower gas pressures• Reduced accuracy, due to reduced chance of a ‘clean burn’ and
velocity variation• Increased weapon fouling• Increased chance of projectile obstructing, due to lower pressure
DSG’s SSP -Subsonic Penetrator solves these issues
Introducing the 7.62x51-SSP (Subsonic Penetrator)
The SSP provides military and LE agencies new and innovative subsonic capabilities
• Reliable Source:– Developed and tested in Norway– Manufactured in the USA (Idaho)
• Maximum effective range: 600m• Highly effective materiel and armor penetration• Low angle penetration• Accuracy: 1.4MOA-Non Optimized• Normal weapon function and cycling• Exceptional cross-wind stability
