Trijicon MRO Objective Flip Cap AC31016

The objective lens on your MRO is exposed to everything your rifle encounters — range dust, field debris, rain, and the general wear of a rifle that gets used hard and carried regularly. A dirty or scratched objective lens affects the red dot brightness and sight picture in ways that matter when fast, accurate target acquisition is the priority. The Trijicon MRO Objective Flip Cap AC31016 keeps the objective lens covered and protected between uses, and completely clears it the instant you need the sight ready to go.

The scope flip cap's spring-loaded mechanism opens with a single fast motion, throwing the cap completely clear of the objective lens without any partial obstruction or delay. For a red dot sight that is used in fast, dynamic shooting situations, that instant clearance matters — you need the sight ready the moment the rifle comes up, not after fumbling with a slow or stiff lens cover. The optic cover spring mechanism remains durable and reliable with regular use, without weakening or becoming inconsistent over time.

The Lens protector AC31016 is designed specifically for the Trijicon MRO objective housing — not a generic flip cap that approximately fits the right diameter. The precise fit means the cap seats securely against the objective bell without gaps that allow dust and debris to reach the lens surface underneath. A cap that fits the specific optic it was designed for stays in place through transport, brush contact, and active field use without loosening or falling off at inconvenient moments.

The scope accessories MRO objective flip cap keeps the objective lens clean and protected during storage, transport, and movement through the field — so the first thing you do when a target presents itself is shoot, not clean the lens.
