.458 SOCOM AMMO

Shop our selection of .458 ammunition for sale. The .458 SOCOM, a round similar to a lighter .45-70 but with a smaller casing, is engineered to fit AR-15s through the addition of a specific bolt and barrel. This 300-grain projectile achieves a supersonic muzzle velocity of 1,900 ft/s and yields a force of 2,405 ft lbf. It arose from special ops, specifically Task Force Ranger, wanting more firepower than the 5.56 NATO used in M4 and M16 rifles.
