Description

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.

The industry standard 1-14 twist barrels seem to be the best choice for over 350 grain bullets and/or subsonic loads and will shoot all suitable bullet weights acceptably well. We recommend this twist rate if you plan to use a suppressor to eliminate the chance of a baffle strike.

The SOCOM is also capable of launching 500- 600 grain bullets at subsonic velocities for suppressed or tactical use.  We recommend blending and polishing the feed ramps for these heavier rounds.

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.

In our opinion the .458 SOCOM has several design and performance advantages over the.450 Bushmaster and the .500 Beowulf including improved functional reliability and the use of a standard AR magazine.

Our 458 SOCOM Lightweight Billet Complete Upper is a light, fast moving upper incorporating the very best components the industry has to offer.  We start with our billet slick side teflon coated upper receiver. We then mate our 15″ free floating slim keymod rail and add a Tromix lightweight barrel, along with a Strike Industries lightweight, low profile gas block and melonite gas tube.  At the end we use a 4 prong flash hider.

Mate this with one of our Mystic Black BCGs for and incredibly reliable, low maintenance package.
