*It is HIGHLY recommended to run this upper with a D&H Tactical 458 Socom Magazine for zero feed issues and our 458 bolt carrier group. It is a 458 Socom bolt carrier group with a genuine 458 Socom bolt assembly. It is highly recommended to use our brand bolt with 458 Socom uppers/barrels to eliminate feeding and extraction issues that are common to 458 Socom's that do not use this bolt. Our 458 Socom bolt assembly has MANY specific, unique and purposeful features about it that other brand 458 Socom bolts do not have. These features are absolutely critical for reliable, consistent performance in 458 Socom uppers. We have them available for purchase on our website.

***WARNING ABOUT 458 SOCOM's***

  • LOADING:

    .458 SOCOM rifles and upper halves should always be loaded from a magazine. Do not load singly through the ejection port, a slam fire can occur upon bolt release.
  • ALUMINUM GI MAGS ONLY:

    .458 SOCOM rifles and upper halves should only be fed from aluminum magazines. Polymer magazines can swell and rounds can shift creating opportunities for misfeeds, jams, and other issues that don’t occur with the aluminum mags.
