Frequently Asked Questions - ACOG TA33 3x30 Trijicon
How do I mount the Trijicon ACOG TA33 3x30 to my rifle?
The ACOG TA33 comes with an integral mounting system that attaches directly to a Picatinny (MIL-STD-1913) rail. Place the scope on the rail, align the recoil lug, and tighten the mounting screws to the specified torque (typically 65 in-lbs) using a torque wrench. Ensure the scope is level before tightening.
Does the ACOG TA33 3x30 require batteries?
No, the reticle is illuminated using fiber optics and tritium. The fiber optic collects ambient light to adjust brightness, and tritium provides a constant low-light illumination for up to 15 years. No batteries are needed.
How do I zero the ACOG TA33 3x30?
Zeroing is done by adjusting the windage and elevation turrets. Each click equals 0.5 MOA (approximately 0.5 inches at 100 yards). Loosen the locking screws, turn the turrets in the desired direction, then retighten. A typical initial zero at 100 yards with a 5.56mm rifle is recommended.
What is the eye relief on the TA33?
The eye relief is 1.5 inches. This is relatively short, so mount the scope as far back as possible on the receiver for comfortable shooting. It is designed for fast target acquisition.
Is the ACOG TA33 waterproof?
Yes, the scope is waterproof to a depth of 66 feet (20 meters). It is also fogproof due to nitrogen purging, ensuring clear viewing in harsh conditions.
What reticle options are available for the TA33?
The TA33 3x30 typically features a BAC (Bindon Aiming Concept) reticle with a chevron or crosshair. Common reticles include the Red Chevron (for 5.56mm) or Green Crosshair. The reticle is illuminated and color depends on model.
How do I clean and maintain the lenses?
Use a soft, lint-free cloth or lens brush to gently remove dust. For smudges, use a lens cleaning solution designed for optics. Avoid solvents like alcohol or acetone, as they may damage lens coatings. Keep the lens covers closed when not in use.
Can I use the TA33 on a .308 or other calibers?
Yes, the TA33 is calibrated for 5.56mm but can be used on other calibers like .308 with proper holdover adjustments. The factory BDC (Bullet Drop Compensator) reticle is tuned for specific loads; for other calibers, you may need to calculate your own holds.
What is the field of view at 100 yards?
The field of view is 36.8 feet at 100 yards. This provides a wide viewing area for quick target acquisition and situational awareness.
Does the ACOG TA33 come with a warranty?
Yes, Trijicon offers a limited lifetime warranty that covers defects in materials and workmanship. It does not cover damage from misuse, abuse, or unauthorized modification. Register your product online for warranty service.
