Cross Armory LEGION Glock 17 Barrel Gen 1–4

Description

The Cross Armory LEGION Barrel for Glock 17 & G-Series Compatible Frames represents the fusion of historical inspiration and modern engineering. Modeled after the discipline and dominance of the Roman LEGION, this barrel is engineered for shooters who demand uncompromising performance, precision, and reliability.

Crafted from billet RHC45 heat-treated stainless steel, the LEGION barrel is CNC-machined to strict SAAMI specifications with a 1:10 twist rate and held to tolerances as tight as ±0.0005 inches. The result is a match-grade chamber delivering consistent accuracy and repeatable performance.

The fluted barrel profile reduces overall weight while increasing surface area for improved cooling and thermal stability. A polished feed ramp ensures smooth, reliable feeding across a wide range of ammunition types. Roman numeral caliber and model markings reinforce the LEGION theme while providing universal identification.

While designed to visually and mechanically match Cross Armory LEGION slides, this barrel performs flawlessly as a standalone upgrade and is fully compatible with factory Glock slides and Glock-compatible frames.
