CMC Triggers 75523 Glock 19 Bronze Threaded Barrel

In the realm of precision shooting, the barrel is not merely a component; it is the heart and soul of accuracy. Our barrels are crafted with an unwavering commitment to excellence, embodying both engineering prowess and meticulous attention to detail.

The foundation lies in our choice of material—pre-hardened 416R stainless steel—selected for its superior strength and durability. This alloy undergoes a rigorous stress-relief process post-rifling, ensuring stability that withstands even the most demanding conditions. With a final hardness rating between 38-42 on the Rockwell C scale, this barrel promises reliability under pressure.

Each barrel features a six-groove cut rifled design with a right-hand twist rate of 1:10. Such configuration enhances bullet stabilization during flight, contributing significantly to shot consistency—a critical factor for those who demand nothing less than match-grade performance.

Our manufacturing precision does not end there. The bore is double honed—both rough and finish—to deliver an unparalleled smoothness with a maximum Roughness Average (RA) of just 12. Finished dimensions are held within an astonishing tolerance level of ±0.0005 inches from nominal groove measurements but maintain uniformity within an incredible margin of only ±0.0002 inches across all points.

This dedication extends into chamber crafting as well, adhering strictly to SAAMI Match Grade specifications with chambers meticulously cut and finished to achieve up to RA16 smoothness.

Finally, each barrel receives bead blasting treatment resulting in an elegant satin finish before plating—a testament not only to aesthetics but also corrosion resistance enhancement.
