Trijicon ACOG Adjuster Caps for 1.5x16, 1.5x24, 2x20, 3x24, 3x30 Scopes
ACOG scopes are built tough for serious shooters, but those adjustment caps protecting your windage and elevation turrets? They're easy to lose in the field. The Trijicon ACOG Adjuster Caps replacement set keeps your dial adjustments protected and your zero secure. This two-pack fits five popular ACOG models—1.5x16, 1.5x24, 2x20, 3x24, and 3x30—so whether you're running a compact combat optic or a higher-magnification hunting scope, you've got a spare handy.
Dust, dirt, and accidental knocks against gear or hard cover can shift an unprotected turret. Those caps aren't just cosmetic—they're functional armor for the adjustments that hold your duel zero. Keep a replacement set in your range bag or backup kit so a lost cap doesn't mean a trip back to zero or a scope swap mid-mission.
Installation is straightforward: the caps seat firmly on the turrets and remove cleanly when you need to dial. They're black to match standard ACOG finishes, and they're made to the same tight tolerances as Trijicon's originals, so you get the same solid fit and feel.
