Trijicon ACOG 4x32mm Tritium Illuminated Riflescope - .223 / 5.56 NATO BDC Amber Crosshair Reticle, Integrated Back-Up Iron Sights, Thumbscrew Flattop Mount, Forged 7075-T6 Aluminum Housing, Cerakote Flat Dark Earth (FDE) Finish - TA01-D-100319 / 719307307339
Product Description
Staging an AR-15 for combat readiness, low-light tactical operations, or long-range target identification requires an optical sight engineered to perform without relying on vulnerable electronic batteries. Variable power scopes and standard red dots introduce battery depletion risks, fragile turrets, or slow eye-box alignment that fails under dynamic high-stress conditions on your bench. The **Trijicon® ACOG® 4x32mm Tritium Riflescope (TA01-D-100319 / 719307307339)** flatlines these optical limitations, delivering fixed **4x magnification** backed by a self-luminous tritium illuminated ballistic reticle clad in Cerakote Flat Dark Earth (FDE).
Proudly designed, CNC-machined, and hand-assembled in Wixom, Michigan by Trijicon, the TA01-D-100319 features a heavy-duty housing forged from ultra-dense **7075-T6 aircraft-grade aluminum alloy** treated with a durable Cerakote FDE finish. The combat-proven optics package incorporates multi-coated broadband glass lenses that yield crystal-clear light transmission with zero distortion. Operating completely battery-free, the reticle uses a black crosshair during daylight hours that seamlessly transitions to a self-luminous **amber tritium glow in total darkness**. Calibrated specifically for 55-grain to 62-grain .223 Remington / 5.56x45mm NATO ballistics out to 800 meters, this optic includes integrated back-up iron sights (BUIS) mounted directly on top of the scope body and comes paired with a TA51 thumbscrew flattop mount straight from your armorer bench.
Engineered to mount directly onto standard MIL-STD-1913 Picatinny receiver rails, this combat-proven fixed-power sight guarantees absolute zero retention directly from your workspace bench.
*Armorer Bench Notes & Real-World Combat Optic Staging Guidance: The Trijicon TA01-D-100319 ACOG arrives workspace ready inside a heavy-duty padded hard storage case complete with a TA51 thumbscrew mount, rubber scopecoat cover, LENSPEN cleaning tool, and instruction manual. BATTERY-FREE TRITIUM ILLUMINATION & BDC MATRIX: This model relies on an internal **tritium lamp** that glows continuously in low-light environments without batteries, switches, or external fiber optic tubes. *Ballistic Drop Calibration Checklist:* The amber crosshair BDC reticle is calibrated for standard **.223 Rem / 5.56mm NATO ammunition fired from a 16-inch barrel**; range hashmarks allow instant holdover corrections out to 800 meters without dialing windage or elevation turrets. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host rifle is completely clear of live ammunition, the magazine is removed, and the chamber is checked safe and empty. 2. Clean the upper receiver Picatinny rail slots using a dry lint-free shop towel to remove excess oil or storage grease. 3. Position the ACOG onto the top rail, ensuring proper eye relief (~1.5 inches) before tightening the base mount. 4. Hand-tighten the two TA51 side thumbscrews clockwise, then add a 1/4 turn using a coin or flathead driver to achieve approximately **50 to 65 inch-pounds** of torque on your bench. 5. Remove the tethered turret caps and adjust windage/elevation dials (1 click = 1/2 in at 100 yards) using a coin to zero the reticle. 6. Verify line-of-sight alignment through the integrated top iron sights before rolling downrange.*
