Calibrated for 0.308, the ACOG (Advanced Combat Optical Gunsight) TA55A 3.5x35 scope with Red Chevron BAC Reticle 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 TA55A 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 TA55A Scope comes complete with a Scopecoat to safeguard the scope from dings and scratches, dust, dirt, and moisture in the field and a Lenspen that makes it safe and easy to clean the scope's lens in the field.

Features:

• Trijicon Fiber Optics: Automatically adjusts the brightness level and contrast of the reticle to available light conditions.
• Bindon Aiming Concept (BAC): Trijicon ACOG models equipped with BAC allow use of the both-eyes-open aiming method along with scope magnification sighting for rapid target acquisition--in any light.
• Broad Band Anti-Reflective Coated Lenses: Multi-coated lenses provide superior clarity and light gathering capabilities with zero distortion.
• Trijicon Tritium Phospor Lamp: Aiming reticle glows in low-light conditions for quick target acquisition--with no batteries to fail. Lamp is guaranteed to illuminate for up to 15 years.
• Internally Adjustable: Since only the prism housing moves, the ACOG is much more rugged than conventional designs.
• Longer Eye-Relief: Maximum eye-relief for larger caliber rifles and large exit pupil for faster target acquisition.
• Military-Grade Aluminum Alloy Housing: Forged 7075-T6 aircraft aluminum alloy housing provides for a nearly indestructible sighting system.
• Waterproof to 100 Feet/30 Meters: Dry nitrogen filled to eliminate fogging.
• Totally Battery Free: Trijicon ACOG delivers increased hit potential in all lighting conditions--without the use of failure-prone batteries.

    About ACOG (Advanced Combat Optical Gunsight) Riflescopes:
    Trijicon ACOG riflescopes are internally adjustable, compact telescopic sights with tritium illuminated reticle patterns for use in low light or at night. The ACOG's combine traditional, precise distance marksmanship with close-in aiming speed. Designed for use with the M16 family, every feature of the ACOG's mechanical and optical design was chosen for a single purpose: to provide increased hit potential in all lighting conditions--without failure-prone batteries.

    With a dual-illuminated reticle, the Trijicon ACOG provides shooters with a distinct aiming point in all light conditions--without batteries. Powered by a tritium-phosphor lamp, the gunsight's reticle glows in low-light conditions, while advanced fiber optics automatically adjust the brightness level and contrast of the reticle in brighter light conditions. Broadband, anti-reflective coated lenses provide superior clarity and light gathering capabilities with zero distortion. The ACOG also offers large eye volume, giving you greater leeway--fore and aft, and from side to side--with which to see through the lens. Of course, once the target is acquired, the ACOG is a trusted ally to help you zero in on a perfect shot.

    The ACOG is crafted with a tough, military-grade, aluminum-alloy housing and is waterproof to depths of 500 feet--making it nearly indestructible. Only the prism housing moves, so it's much more rugged than conventional designs. And the ACOG does not require failure-prone batteries--so you can rely on it to perform in practically every situation.

    Bindon Aiming Concept (BAC):
    Bindon Aiming Concept (BAC) ACOG Riflescopes feature bright daytime reticles using fiber optics, which collect ambient light. This revolutionary, both-eyes-open aiming method provides you with 'instinctive' target acquisition and increased hit potential. And, the scope's ranging is built into many of its reticles, so you only need to set zero once for a multitude of ranging distances.

    ACOG Scopecoat:
    The Scopecoat is constructed of the highest quality neoprene laminated with nylon. Its simple design safeguards the scope or sighting system from dings and scratches, dust, dirt, and moisture. Neoprene has 5 percent greater moisture absorbency, which takes moisture (condensation and sweating) away from the scope or sight and helps protect it from rust and corrosion. The nylon laminate shields the scope against the elements. Simply stretch both ends of the Scopecoat over your ACOG sight for optimum field protection.

    Lenspen:
    The Lenspen features a safe and easy to use retractable dust removal brush and a special non-liquid cleaning element, designed to never dry out.
