Dial Indicator

The Dial Indicator by COMP CAMS is a precision measurement instrument built for professionals who demand accuracy in engine building, firearm assembly, and mechanical diagnostics. Whether you're a gunsmith, law enforcement armorer, military small arms technician, or automotive enthusiast, this tool delivers repeatable measurements critical to performance tuning and component verification. The dial indicator is an indispensable asset for anyone who needs to verify runout, measure bearing clearances, check timing chain stretch, or validate chamber dimensions with sub-thou tolerances.

Engineered by COMP CAMS—a trusted name in precision measurement and engine performance—this dial indicator features a robust design built to withstand field and workshop environments. The mechanism reads incremental movement with the precision required for critical clearance work, making it essential for bolt carrier group inspection, bolt carrier key gap verification, or piston rod measurement in direct impingement systems. The compact 6.4 x 2.7-inch footprint and 0.7 lb weight make it portable enough for range diagnostics while maintaining the rigidity necessary for stable, repeatable readings on metal and composite surfaces.

Tactical armorers, gunsmiths, and maintenance personnel rely on dial indicators to troubleshoot feeding reliability issues, validate headspace, and detect component wear before failures compromise mission capability. This tool pairs seamlessly with calipers, micrometer stands, and V-blocks for comprehensive part assessment. Professionals in law enforcement firearms units, military small arms repair facilities, and civilian gunsmith shops use COMP CAMS dial indicators as a core diagnostic instrument for quality control and performance verification. For anyone managing a fleet of firearms or performing precision mechanical work, this indicator delivers the measurement confidence required for consistency and safety.
