Think of the .458 SOCOM as a .45-70 in a modern AR platform weapon. It’s capable of firing 250gr through 600gr bullets, however is best suited for bullets in the 250gr – 400gr range for hunting. It’s at it’s very best when firing the purpose built Barnes 300gr TAC TX bullet in the 1750fps – 1800fps velocity range. However the SOCOM will also fire 500gr - 600gr bullets subsonic for tactical purposes. Building the .458 SOCOM takes only the following “unique” parts: Barrel, bolt and extractor. However Wilson Combat is optimizing their .458 SOCOMs by also adding their new adjustable gas block and straight gas tube as a standard feature. Having the ability to adjust your gas volume allows the end user to fine tune their carbine for a specific load. In addition minor machining has to be done to the ejection port opening of the upper receiver to allow clearance for the larger cartridge case. The SOCOM feeds flawless from many standard unmodified 5.56 AR magazines, however Wilson Combat has found the Lancer L5 AWM magazine to be optimal. The standard 20rd magazine holds 7 rounds and the 30rd holds 9. One really nice attribute of the SOCOM is the fact that it doesn’t require a long barrel to achieve its optimum performance level, very little can be gained with a barrel length over 16”. In our opinion the .458 SOCOM has several design and performance advantages over the .450 Bushmaster and the .500 Beowulf, two of which are improved functional reliability and the use of a standard AR magazine.
