Trijicon ACOG Adjuster Caps & Lanyard AC10003

Keeping your ACOG's adjustment turrets properly protected and the lanyard system intact is one of those maintenance details that keeps a combat optic in proper working condition through hard use over time. The Trijicon ACOG Adjuster Caps and Lanyard AC10003 gives ACOG owners a direct replacement for the original adjuster caps and lanyard assembly - restoring complete turret protection and the tethered cap system that prevents small components from being lost in the field during adjustments.

The Trijicon scope cap AC10003 adjuster caps seal the elevation and windage turret adjustment mechanisms against moisture, dust, and debris that work their way into unprotected turrets during field use. Exposed turrets on a combat optic accumulate the kind of contamination that affects the tactile feel of adjustments, accelerates corrosion on adjustment components, and in worst cases allows unintended movement that shifts zero without any intentional input. Properly fitting adjuster caps prevent all of that, keeping your ACOG's adjustment mechanisms clean, protected, and functioning properly under the demanding conditions combat and tactical use regularly produce.

The lanyard assembly tethers the adjuster caps to the ACOG housing, keeping them connected to the scope during adjustments and preventing them from being set down and forgotten or dropped in conditions where retrieving a small component is difficult. For operators who make field adjustments in demanding environments where losing small parts is a real operational concern, the tethered lanyard is the practical detail that eliminates that risk. The Trijicon ACOG accessories AC10003 lanyard system restores that tethered connection when the original becomes damaged or worn.

The AC10003 is designed specifically for compatible ACOG configurations - a direct replacement that installs correctly on the original turret threads without modification.
