With the same rugged precision as the legendary Trijicon ACOG, the Trijicon 4x32 Battery ACOG delivers robust engineering and enhanced user control. Powered by a single AA battery, the electronics offer an outstanding level of reliability with a straightforward brightness dial, allowing the operator to determine how much to illuminate the reticle-even in transitional lighting. The body has been optimized by moving the RMR mount forward to maximize its performance in conjunction with the ACOG. Fully night vision device compatible, the Trijicon 4x32 Battery ACOG is also compatible with most other 4x32 ACOG accessories available.Bullet Drop CompensatorWeight: 18.1 oz with TA51 Mount & Alkaline BatteryLED Illumination SourceBindon Aiming Concept7 Degrees Field of ViewAdjustment @ 100 yards: 2Forged Aluminum HousingBattery Life: 12,000 hrs on setting #4Includes:1 Thumbscrew Flattop Adapter (TA51)1 AA Battery1 LENSPEN (TA56)1 Lanyard Assembly for Adjuster Caps (TA71E)1 Lanyard Assembly for Battery Cap1 Trijicon Logo Sticker (PR15)1 Manual1 Warranty Card
