***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 Awesome Quality!! January 10, 2020
Reviewer: Mike Brown from Canton, MI United States  
If you are looking to build a 458 Socom and you’re looking for a upper to buy, look no further! Tromix is one of the top brands to go with, the quality is definitely there! After adding in the extras with this (Complete Upper) it was about $600-650 which really isn’t bad especially for getting name brand that has proven to stand behind its name

Yes you can always buy a cheaper brand and I’m sure you’d be fine but buying the Tromix brand buys you the peace at mind knowing that when you complete you’re build and fire your firearm it won’t leave you stranded with low grade quality parts that will not leave you sitting around with a malfunctioning firearm

Folks stop in here and order your Tromix 458 Socom upper, you won’t be disappointed!

Also another tip if you are unsure about which AR15 lower to buy, ANY brand AR15 will work with this

You’re Welcome :)
