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). The body has been optimized by moving the RMR mount forward to maximize its performance in conjunction with the ACOG. 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. Fully night vision device compatible the Trijicon 4x32 LED ACOG is also compatible with most other 4x32 ACOG accessories available. - The 300 blackout reticle with merged aiming points has been optimized for simplicity and efficiency. It allows the user to instantly switch between supersonic and subsonic ammunition without having to re-zero the weapon. The supersonic BDC (out to 600 yds.) has been merged with the subsonic BDC (out to 200 yds.) to provide one set of aiming points for both types of ammunition. The reticle drops are based on an average of commonly available off-the-shelf subsonic and supersonic ammunition. This BDC reticle is not limited to one or two specific bullets: a majority of commonly available ammunition will fall within the 2 MOA diamond aiming points. The 2 MOA diamonds offer a balance of speed and versatility based on the unique performance of the 300 Blackout caliber. The drops for each aiming point are provided for users who wish to develop their own handloads or for those who wish to deviate from the recommended zero distances. - 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 Manual - 1 Warranty Card - Magnification: 4x - Objective Size (mm): 32mm - Bullet Drop Compensator: Yes - Length (in): 6.0 in - Weight (oz): 18.1 oz. with TA51 Mount and Alkaline Battery - Illumination Source: LED - Reticle Pattern: Crosshair w/ Merged Aiming Points - Day Reticle Color: Red - Night Reticle Color: Red - Calibration: 300 BLK - Bindon Aiming Concept: Yes - Eye Relief (in): 1.5 - Exit Pupil (mm): 8 - Field of View (Degrees): 7 - Field of View @ 100 yards (ft): 36.8 - Adjustment @ 100 yards (clicks/in): 2 - Mount Comes With: TA51 - Housing Material: Forged Aluminum - Batteries: Single AA Lithium or Alkaline Battery - Battery Life: Over 12000 hours on setting #4 using supplied alkaline battery at 21ºC (70ºF)
