Designed to destroy light armour from a distance, the M-109 is a semi-automatic 25mm rifle that has a 17.6 inch long barrel and an overall length of 46 inches. It weighs in at 46 pounds and has a 5 round magazine. In comparison, the Barrett M107 .50 caliber sniper rifle in general use today has a 29 inch barrel, overall length of 57 inches, and weighs in at a mere 32 pounds, with a magazine capacity of 10 rounds.
To complement this “rifle” optic is a computerized sight called the ORS (Optical Ranging Sighting System). ORS is specifically designed for long-range shooting at 1,000 meters and longer distances, measuring and compensating for air pressure, temperature, and the angle of the weapon in relation to the target.
Precisely compensating for all these factors and successfully hitting the target on the first shot is possible, but difficult. BORS is designed to take all the sweat-math work out of first-round shots, leaving the operator with simply dialing in the distance to target, selecting the ammunition type, and putting the cross-hairs on the target. Future versions of BORS will incorporate a rangefinder, and night vision capability.
A spiked bipod is included to steady the M-109 for firing and it has a standard M1319 accessory rail for scopes and other accessories. It also has the ability to remove the muzzle break and replace it with a specially designed sound suppressor.
Effective distance armor piercing “lethality” for the rifle is listed at 2000 meters. The 25mm round is derivative design from the AH-64 Apache helicopter’s M789 high-explosive dual purpose (good against armor and personnel) 30mm ammunition and will penetrate at least 50 millimeters of armor plating, making it capable of destroying light armored vehicles, SCUD launchers, and other equipment. The 25mm round is 2.5 times more effective at destroying targets than a .50 caliber armor-piercing round.
The M109 is a special issue weapon, and is not often seen except for some reconnaissance and special forces units. It can be useful in urban situations when a precise light armour piercing capability is required.
