***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.

5 of 5 Great parts and service. August 11, 2019
Reviewer: Brenten Young from Wichita , KS United States  
One of the fastest shipping out there and all the parts are high-quality with a very competitive price. My 458 got to my house in 2 days and I didn't have to pay for expedited shipping.

5 of 5 Seriously awesome. March 10, 2019
Reviewer: Nathaniel Tindall from Oregon.  
Always wanted to build a big bore AR. I was very pleased with the quality of the upper and a good price. Very happy with the results. Can’t wait to shoot it once my forarm brace shows up.
