Two Grades.
One Manufacturing Standard.
Service Grade and Air Gauged Match Grade are built from the same materials and core manufacturing process. The difference is the level of dimensional qualification and selection.
Service Grade vs.
Air Gauged Match Grade.
Built To Run.
MNKY Service Grade barrels are designed for duty rifles, training rifles and high-round-count applications where reliability, durability and long service life are the priority.
Service Grade barrels are manufactured using the same core processes as Match Grade barrels and receive the same chrome-lined bore and chamber, HP proof testing and MP inspection.
They meet MNKY production acceptance requirements but are not selected to the tighter bore and groove dimensional-consistency requirements established for Air Gauged Match Grade barrels.
Selected For Precision.
Air Gauged Match Grade barrels are for shooters who want the durability of a hard-use chrome-lined barrel with enhanced dimensional consistency.
Each Match Grade barrel is precision air gauged and must meet tighter requirements for bore diameter, groove diameter and dimensional consistency throughout the length of the barrel.
Only barrels meeting those requirements receive the MNKY Air Gauged Match Grade designation.
What Makes Match Grade Different?
The client material recommends treating Air Gauged Match Grade as a measurable specification rather than simply a marketing label. That means establishing internal limits for bore diameter, groove diameter and allowable deviation over the barrel length.
