Gunn Ammo. $ 16 per 20 rds. MK319 Mod 0 7.62MM Cartridge, Caliber 7.62mm Ball, Rifle, Barrier MK 319 MOD 0 DODIC: AB50 NSN: 1305-01-572-8492 Federal Part # T762TNB1 The open-tipped rounds until now have been available only to Special Operations Command troops. The first 200,000 7.62 Special Operations Science and Technology rounds are already downrange with Marine Expeditionary Brigade-Afghanistan. SOCOM developed the new rounds for use with the Special Operations Force Combat Assault Rifle, or SCAR, which needed a more accurate bullet because its short barrel, at 13.8 inches, is less than an inch shorter than the M4 carbine’s. Using an open-tip match round design common with some sniper ammunition, SOST rounds are designed to be “barrier blind,” meaning they stay on target better than existing M855 rounds after penetrating windshields, car doors and other objects. This ammo is made by Gunn Ammunition, INC in Blakely, GA. Owned by US Marine veterans and made by Army veterans. We use the same machines as Hornandy, Remington and others.
