Stainless steel sleeve, plus stainless steel and tungsten inserts
help cure pressure and cycling problems caused by high-pressure,
heavy-bullet loads. Up to 4.05 ounces of additional weight lets you
keep the bolt locked longer and tune carrier inertia to soften
rearward movement. Improves brass life and velocity, plus reduces
bolt stop overtravel for increased engagement and life span.
