From the legendary ACOG® family of products the LED ACOG is the first to offer user-selectable brightness controls. Users can select from six adjustable brightness levels with an off between each setting allowing the operator to determine how much to illuminate the reticle-even in transitional lighting. Powered by a single AA battery the LED ACOG can run for over 12000 continuous hours (on setting #4). Like all ACOG models it is forged from rugged 7075-T6 aircraft-aluminum resulting in a nearly indestructible sighting system and electronics that offer outstanding reliability. Users can select multiple bullet drop compensating and ranging reticle options. Fully night vision device compatible the Trijicon 3.5×35 LED ACOG is also compatible with most other 3.5×35 ACOG accessories available. – Package Includes: – 1 Thumbscrew Flattop Adapter (TA51) – 1 AA Battery – 1 LENSPEN® (TA56) – 1 Lanyard Assembly for Adjuster Caps (TA71E) – 1 Lanyard Assembly for Battery Cap – 1 Trijicon Logo Sticker (PR15) – 1 LED ACOG Manual – 1 Warranty Card – Magnification: 3.5x – Objective Size (mm): 35mm – Bullet Drop Compensator: Yes – Length (in): 8.0 in. – Weight (oz): 16.8 w/out mount – Illumination Source: LED – Reticle Pattern: Chevron – Day Reticle Color: Greem – Night Reticle Color: Green – Calibration: .223 – Bindon Aiming Concept: Yes – Eye Relief (in): 2.4 in. / 61.0mm – Exit Pupil (mm): 0.39 in. / 10.0mm – Field of View (Degrees): 5.5 – Field of View @ 100 yards (ft): 28.9 – Mount Comes With: TA51 – Housing Material: Forged Aluminum – Batteries: 1 AA Alkaline or Lithium Battery – Battery Life: Over 12000 hours on setting #4 using supplied alkaline battery at 21ºC (70ºF) – Adjustment Increments (Range to Target): 2 click per in. @ 100m – Adjustment Range: 40 MOA Total Travel – Illumination Settings: 6 – Dimensions (LxWxH): 8.0 x 3.0 x 2.6 in 203 x 76 x 66mm
