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 3.5x35 LED ACOG is also compatible with most other 3.5x35 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: Horseshoe Dot - Day Reticle Color: Red - Night Reticle Color: Red - 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
