Product description ------------------- Trijicon Acog , 5.5x50, Red Chevron Reticle .308, Includes Flattop Adapter, Matte Finish Ta55a Model: ACOG Product Type: Finish/Color: Matte Accessories: Flattop Adapter .com ---- Calibrated for 0.308, the ACOG (Advanced Combat Optical ) TA55A 3.5x35 with Red Chevron BAC Reticle offers precision ing in any light conditions without the use of batteries for a fail-safe performance. Coming complete with an ACOG TA51 flattop, Picatinny rail adapter with colt style thumbscrews, the is easy to on most standard rails. The '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 ing Concept (BAC), the provides 'instinctive' target acquisition and increased hit potential. The TA55A 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- and large exit pupil for ease of use. Constructed of -grade aluminum alloy, the is dry nitrogen filled, and waterproof to 100 feet/30 meters. The '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 comes complete with a coat to safeguard the from dings and scratches, dust, dirt, and moisture in the field and a Lenspen that makes it safe and easy to clean the 's lens in the field. Features: * Trijicon Fiber Optics: Automatically adjusts the brightness level and contrast of the reticle to available light conditions. * Bindon ing Concept (BAC): Trijicon ACOG models equipped with BAC allow use of the both-eyes-open ing method along with magnification ing 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: ing 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-: Maximum eye- for larger caliber s and large exit pupil for faster target acquisition. * -Grade Aluminum Alloy Housing: Forged 7075-T6 aircraft aluminum alloy housing provides for a nearly indestructible ing 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.

TA55A dual illuminated , TA51 , 5.5x50 coat, Lenspen, Trijicon Logo Sticker, Manual, warranty card Manufacturer Warranty Limited Lifetime: optical systems and metal structure; 15-years: Tritium lamp About ACOG (Advanced Combat Optical ) s: Trijicon ACOG s are internally adjustable, compact telescopic s with tritium illuminated reticle patterns for use in low light or at night. The ACOG's combine traditional, precise distance marksmanship with close-in ing 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 ing point in all light conditions--without batteries. Powered by a tritium-phosphor lamp, the '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 . The ACOG is crafted with a tough, -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 ing Concept (BAC): Bindon ing Concept (BAC) ACOG s feature bright daytime reticles using fiber optics, which collect ambient light. This revolutionary, both-eyes-open ing method provides you with 'instinctive' target acquisition and increased hit potential. And, the 's ranging is built into many of its reticles, so you only need to set zero once for a multitude of ranging distances. ACOG coat: The coat is constructed of the highest quality neoprene laminated with nylon. Its simple design safeguards the or ing 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 or and helps protect it from rust and corrosion. The nylon laminate shields the against the elements. Simply stretch both ends of the coat over your ACOG 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.
