The Best .458 SOCOM Uppers in 2023

The .458 SOCOM (Special Operations Command) round is a powerful defensive round with roots in military history. The best .458 SOCOM Upper Receivers seamlessly handle the firepower this round produces and are engineered to perform in the harshest combat conditions.

We’ve provided our selections in both complete and stripped uppers so you can pick the product that best suits your intended purpose — build or buy. Note: complete uppers are easier to implement but are considerably more expensive than stripped uppers.

That said, you’ll need to bring your own charging handle, dust covers, barrel, and other upper components to complete the build, so price out your options carefully for a true apples-to-apples comparison. This article is part of our ongoing Guide to Everything AR.
