The 458 SOCOM, (SOCOM is an acronym for Special Operations Command), is an awesome cartridge that is basically a lengthened 50AE case, necked down to accept .458 projectiles, a over all length of 1.575", and with a rebated .308 head configuration. This cartridge is chambered in AR-15 platform rifles as well as Bishop Ammunition Manufacturing's Bolt Action Rifle. You can buy a complete AR-15 style rifle, (California Compliant and standard configuration), or just the complete upper receiver (with bolt carrier group), which mounts to any AR-15 style lower receiver with zero modifications, from Bishop Ammunition Manufacturing, LLC.

The 458 SOCOM was developed because of the lack of power inherent in the 5.56 NATO cartridge used in the M4 Carbine and the M16 Rifles currently in use in The United States armed forces. Members of the special operations command, Task Force Rangers, experienced dissatisfaction and concern that multiple shots were necessary to neutralize enemy combatants in Mogadishu.

This cartridge is designed to be 100% compatible with M4, M16, and AR-15 rifle platforms. There is no change to the buffer, buffer spring, charging handle, stock, GI Specification magazines, most aftermarket magazines, or the magazine well, trigger assembly or any other components of the lower receiver. The 458 SOCOM singles stacks in 5.56 magazines. A 10 round 5.56 magazine holds four (4) 458 SOCOM rounds. The 20 round magazine holds seven (7) rounds. The 30 round magazine will hold tern (10) rounds of 458 SOCOM.
