The Roman LEGION was the most powerful War Machine in the ancient world. 


While all legions played an important role, only a few gained great fame. Highly disciplined, well-organized, and fearsome, the Roman army was arguably the greatest military force in world history.   The Cross Armory LEGION series of Slides and Barrels are at the forefront of engineering excellence, giving its users an unfair advantage over their adversaries, similar to the history of the Legions, who wielded only the best and defeated all in their way.  We crafted this barrel from the books of history and technology of the future, designed to have function follow form, likening the design to the Romans.  The caliber and model are called out in Roman numerals, that call out the caliber and the model fitment, giving a universal understanding of form and function in any language, on any battle field.  The barrel fluting lending design to the great Roman pillars of the earth, while serving function to your weapon.

The LEGION series is designed to match slide and barrel, but all LEGION parts can work flawlessly and independently with any factory slide or barrel combination.  This barrel is crafted from billet Stainless Steel and CNC machined to the highest SAAMI standards.  With reduced weight and a match grade chamber.  The weight has been reduced on the chamber block without compromising function.  The performance has been increased by fluting the barrel body, increasing the surface area for cooling and increasing material temperature stability and leading to better repeatable accuracy and performance.


At Cross Armory, we elevate accuracy and innovation.
