The Tromix 458 Socom bolt assembly has MANY specific, unique and purposeful features about it that other brand 458 Socom bolts do not have.

***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 Finally one that works! January 12, 2020
Reviewer: Andrew from USA  
Got so frustrated with my bear creek upper and the constant failure to feed issues that I sold it.  Read through the description and it seemed like these guys had their act together so I rlled the dice.  Upper fits great and performed flawlessly.  Mags work great too.
Really happy I could choose cerakot options too.  Will definately buy here again.

5 of 5 Great deal December 17, 2019
Reviewer: Waylon from Jonesboro, LA  
Best deal I could find after scouring the internet for a new 458 upper.  Quaility build with quality components.  Shoots very well.  Had a two FTFs on the very first mag but none after that.  75 rounds down range and sighted in now.  Can't wait to geaux hunt with it.

5 of 5 458 16 inch - Imma lovin this thing December 9, 2019
Reviewer: Jeff Rogers from West  
First time out I had some feeding issues - totally my fault - was to anxious to try it out and didn't lube anything. I gave it a good clean and lube and next time out zero trouble and very tight groups with the buffalo bore 400 grainers - just loaded the empties with Hornady 325 grainers and FTX bullets and can't wait to try these out.

5 of 5 Great find November 14, 2019
Reviewer: Jake Carter from Texas  
Got this thing to keep in my deer stand to make quick work of hogs that steal deer corn.  Works like a champ with zero issues and absolutely lays the hogs flat out.  No problems punching through that thick armor side plate.  Accuracy is great at about 1.5" MOA but it may get even better with hand loads.  Very happy and a must have for pigs.
