(1) Fluted Bolt Aids Reliability. Flutes sweep mud and grit away, helping to keep the action operating smoothly in harsh environments.

(2) Tight Benchrest Tolerances. Decades of experience in the benchrest circuit have shown that absolute concentricity of the bolt and the action body around the axis defined by the
bore line of the barrel is paramount to precision shooting. Each McMillan action is CNC machined from a centerless ground billet blank, not a casting. The face of the action is absolutely perpendicular to the axis of the bolt. Tolerances on general metalwork are held to within 0.005". Critical parts are held to 0.0005" tolerances.

(3) Accepts Remington-Style Trigger. Even the Underside of the McMillan action is a work of art. In a production action, this area is finished poorly with burrs and tool marks to save costs. In contrast, every component of a McMillan action shows precision engineering and attention to detail throughout, whether the area is hidden or exposed.
