The lightweight Wilson Combat .458 SOCOM upper receiver is an engineering marvel, specifically devised to optimize the AR-15 rifle. It has been manufactured with uncompromising precision using 7075-T6 aerospace aluminum billet stock at our world-renowned facility in Wilson. Featuring an anodized finish, and a precisely machined bolt raceway, this upper receiver ensures smoother chambering and greater rigidity of receiver walls for reduced firing flex. Plus, it already comes with the ejection port modification for the larger .458 SOCOM round, so you can hit the range right away. Get your hands on this top-of-the-line receiver and experience maximum performance from your AR-15 rifle!

Caliber Notes: The 458 SOCOM cartridge offers the practical ballistics of the legendary .45-70 in a modern AR platform rifle and is capable of firing 250 to 600 grain .458 caliber bullets in a lightweight, controllable package. For hunting medium to large game, bullets in the 250 grain– 400 grain weight range possess devastating killing power. We have found that the .458 SOCOM offers peak downrange performance when firing the purpose built Barnes 300 grain TAC TX bullet in the 1750fps – 1800fps velocity range.

The .458 SOCOM feeds flawlessly from many standard unmodified 5.56 AR magazines. Our extensive testing has found the Lancer L5 AWM magazine to be optimal for this round. The Lancer 20 round 5.56 magazine holds seven SOCOM rounds and the 30 round 5.56 magazine will hold nine. The .458 SOCOM achieves optimum ballistic performance in barrel lengths shorter than 16” so there is no need for longer, less portable barrels.

NOTE: Wilson Combat rifle parts are intended to provide an easy drop-in fit, but due to the variance in manufacturer tolerances it is possible that some minor fitting may be necessary for proper installation. If you lack experience or confidence in your ability to properly install these parts we STRONGLY recommend consulting with a professional gunsmith prior to proceeding. Failure to do so could potentially result in serious injury or death - USE AT YOUR OWN RISK.
