Corbon ammunition 125gr JHP at 2400fps 7.62x39 Russian is hard to add to a list of urban defense cartridges, but the popularity of inexpensive rifles such as the Romanian SAR-1, Saiga rifles and carbines, VEPR's (semi-auto AK variants), and SKS rifles and carbines as well as chamberings offered in AR-15's makes this an option for some individuals and departments. The cheap imported ammunition does not do justice to these rifles. Cor-Bon is the only company willing to take the effort to improve the ballistics of this cartridge. New top-quality brass is combined with a super accurate 125gr hollowpoint bullet to give you the best the gun is capable of. It's amazing how much better your gun will shoot when you put in quality ammo.
