***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.
