CMC Triggers 75521 Glock 19 Match Grade Threaded Barrel

In the realm of precision firearms, the barrel is not merely a component; it is the very heart of accuracy and performance. The barrels in question are crafted with an unwavering commitment to excellence, embodying principles that would satisfy even the most discerning marksman.

These barrels feature six-groove cut rifling with a right-hand twist at 1:10 ratio—a specification that ensures optimal bullet stabilization for consistent shot placement. Each barrel undergoes rigorous quality control inspections to guarantee reliability and performance under varied conditions.

Attention to detail continues with double honing processes—both rough and finish—yielding an exceptionally smooth bore surface, achieving a maximum Roughness Average (RA) of 12. Such meticulous craftsmanship results in finished bore dimensions held within a tolerance of +/- 0.0005 inches from nominal groove specifications, while ensuring uniformity within 0.0002 inches. This level of precision translates directly into superior consistency and accuracy on target.

Chambers are manufactured to SAAMI Match Grade specifications, precisely cut and polished to achieve a maximum RA of 16, enhancing both function and longevity during operation. The core material used here is pre-hardened 416R stainless steel—a choice made not lightly but through careful consideration for its durability and resistance against wear over time.

Post-rifling stress relief follows an exacting recipe designed to maintain integrity throughout use, resulting in final hardness between Rockwell C38-42 before undergoing profile machining completion. A satin finish achieved via bead blasting provides not only aesthetic appeal but also further protection against environmental factors.

For those who understand that true mastery demands equipment capable of matching their skill set—these barrels represent nothing less than uncompromising dedication towards delivering match-grade performance every time you take aim.
