*It is HIGHLY recommended to run this upper with a D&H Tactical 458 Socom Magazine for zero feed issues and a TROMIX bolt carrier group. It is a 458 Socom bolt carrier group with a genuine Tromix brand bolt assembly. It is highly recommended to use this 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. The Tromix 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.

5 of 5 Great find. October 10, 2019
Reviewer: Charlie McCarter from USA  
Arrived well packed and fast too.  Tried initially hand cycling some rounds and action was very stiff.  Took it to the range and after the first magazine it had loosened up and hand cycling was a breeze.  Guess its just stiff when its new.  Ony shot at 50 yards but had very nice groupings and lots of holes touching.  I would recommend.

5 of 5 Great deal September 11, 2019
Reviewer: Lester Smith from Plant City, FL  
Shipping speed is crazy fast.  Ordered on a Friday had it in my hands on a Wednesday.  Works and cycles as it should with site recommended bcg, plus surprisingly accurate at 100 yards.  Should do good work on hogs.  Very pleased and will return for future business since website is easy to navigate for us old guys!

5 of 5 This upper is great September 6, 2019
Reviewer: Robert C. from FLAGSTAFF, AZ United States  
I got this .458 upper in OD green I love it. No problems at all now. the price of ammo is ridiculous but the upper is fantastic. I had quite a few feeding issues with the buffalo bore flat tip lead bullets. Found out a solution after talking to one of the techs. The mag although rounded doesn't push the bullet up it remains flat. If you stretch the sides of the mag it will force feed the bullet at an upward angle. After that 2 minute adjustment I put 150 rounds through it without an issue. 1 in moa at 100 yards off then bench. Safe to say the piggy's I'm after are in for some trouble
Thanks for the great upper thanks for the call and the tip everything runs great. You'll be hearing from me for the 6.5 creedmoore very soon
