By utilizing their proprietary in-house production system to ensure consistent machining and quality control, CMC is able to produce some of the most precise barrels on the market. This bronze drop-in Glock 17 fluted barrel features an enhanced slide fit and lock up to improve its accuracy, and its finished bore dimensions held to +/- 0.0005" tolerance while staying uniform within 0.0002" for consistency and quality.
Production of this barrel starts with pre-hardened 416R stainless steel that's stress relieved after rifling with a final hardness of 38-42 Rockwell C. Final profile machining is completed and the barrel is bead blasted to give it a satin finish before plating. This drop-in barrel is incredibly user-friendly.
