Calibrated for 0.233, the TRIJICON ACOG 5.5x Red Chevron Riflescope (TA55) offers precision sighting in any light conditions without the use of batteries for a fail-safe performance. Coming complete with an ACOG TA51 flattop, Picatinny rail adapter mount with colt style thumbscrews, the scope is easy to mount on most military standard rails. The scope's Chevron reticle is designed to be zeroed using the tip at 100 meters. The width of the chevron at the base is 5.53 MOA, which is 19 inches at 300 meters. This allows range estimation for silhouette targets.
With the revolutionary, both-eyes-open Bindon Aiming Concept (BAC), the scope provides 'instinctive' target acquisition and increased hit potential. The TA55 scope is further distinguished by its crystal-clear and distortion-free Broad Band Anti-Reflective Coated Lens, Trijicon fiber optics and self-illuminated tritium phospor lamp for totally battery free operation, and maximum eye-relief and large exit pupil for ease of use.
Constructed of military-grade aluminum alloy, the scope is dry nitrogen filled, and waterproof to 100 feet/30 meters. The scope's metal structure and optical system are backed by a lifetime warranty and the tritium lamp is guaranteed to glow for 15 years. The TA55 Scope comes complete with a Scopecoat to safeguard the scope from dings and scratches, dust, dirt, and moisture in the field and a Lens pen that makes it safe and easy to clean the scope's lens in the field.
