Tromix .458 SOCOM Upper – Serious Power, Straight from the Source

Up for grabs is a high-performance .458 SOCOM upper built by Tromix, the original creators of the .458 SOCOM round. This isn't just another upper — it's the real deal, straight from the source.

Specs:

Tromix .458 SOCOM barrel and bolt

Nickel Boron bolt carrier

Bravo Company (BCM) KMR handguard

Troy fixed sights

Includes 60 rounds of .458 SOCOM ammo

This setup has only been fired a couple of times — it's practically brand new. Just drop it onto your standard AR lower and you're ready to go. The ammo runs in standard AR mags, so no need for anything special.

This upper isn’t a budget build — it’s designed for serious use. Not a Bear Creek toy, but a hard-hitting tool that turns your 5.56 into a sledgehammer.
