Trijicon 4x32 RCO Modular ARD AC11011

The Trijicon 4x32 RCO is one of the most widely issued and trusted combat optics in military service — and the Trijicon 4x32 RCO Modular ARD AC11011 gives operators the anti-reflection protection that a field-deployed optic of this caliber deserves. The modular ARD places a precision honeycomb filter over the RCO's objective lens, eliminating forward light reflection that could reveal a shooter's position under bright lighting conditions, with no effect on the sight picture the shooter sees through the optic.

The TA91 modular construction is what distinguishes this ARD from fixed configurations. The modular design allows the anti-reflection device to be attached and removed without tools as the situation demands — keeping the ARD in place when anti-reflection concealment is a priority and removing it quickly when conditions change. For operators who move between different environments and lighting conditions where the ARD's value varies, the modular flexibility is a practical operational advantage that fixed ARD designs cannot provide.

The Trijicon ARD honeycomb structure allows normal light transmission through to the objective lens from the shooter's end while killing the forward reflection that an unprotected 4x32 objective produces in bright light. The result is an objective lens that appears dark from the front — no telltale glint that reveals the shooter's position to targets or observers scanning for equipment signatures in the field. The ARD anti-reflective honeycomb filter produces no vignetting or image quality degradation visible to the shooter.

The AC11011 is designed specifically for the Trijicon 4x32 RCO objective housing — a precise fit that seats correctly on the objective bell and stays securely in place during field use and recoil, without looseness or misalignment that would affect performance.
