RRA LAR-458 .458S SOCOM
A Second Look!
It’s lightweight and compact but packs a car-stopping punch!
It was the Special Forces need for more power and penetration that became the inspiration for the development of the .458 SOCOM cartridge. Firing a projectile twice the diameter of the 5.56 NATO round and churning up more than twice the energy, the new cartridge was designed to function within the parameters of an M-16/AR-15 operating system. Now Rock River Arms (RRA) has started production of their LAR-458: a factory-produced carbine packing the punch of the mighty .458 SOCOM.
Let’s put things in perspective. We all know about the .45-70 that our great grandfathers used to take down buffalos. Remington currently loads a 300-grain JHP bullet with a velocity of 1810 feet per second (fps), which generates 2182 foot-pounds of energy (fpe). The big frontal area of the bullet combined with its velocity made it a devastatingly effective round on game and human alike. But guess what?
