Why does the field of view seem so narrow compared to other scopes?
The TA33's 19.3-foot field of view at 100 yards is designed for tactical applications using both-eyes-open shooting. This fixed-power scope works best with the Bindon Aiming Concept, in which your non-dominant eye provides peripheral vision while the dominant eye focuses through the magnified optic.
Do I need to tap the scope housing after making adjustments?
Yes, the traditional ACOG adjustment procedure requires tapping the housing or cycling the bolt 4-5 times after windage/elevation changes. This "tapping" allows the erector mechanism to settle properly, ensuring accurate point-of-impact shifts. This is a regular ACOG operation, not a defect.
How long does the tritium illumination actually last?
The tritium illumination is accompanied by a 15-year warranty from the date of manufacture for dual-illuminated reticles. However, tritium naturally dissipates over time, which is expected and not covered under warranty if deemed a standard progression. Tritium replacement costs approximately $600.
Is the published 1.9-inch eye relief accurate?
Multiple users report actual eye relief of approximately 3.5-4.0 inches, which is significantly longer than the published 1.9 inches. This generous eye relief allows flexible stock positions and reduces gas/carbon exposure during shooting.
Can I use aftermarket mounts without voiding the warranty?
While Trijicon prefers factory mounts for warranty claims, the Q-LOC mount system is designed explicitly for the TA33. Quality third-party mounts from manufacturers like American Defense and Midwest Industries maintain proper zero retention and are widely used by professionals.
What's the difference between the .223/69gr and other ballistic reticles?
The .223/69-grain ballistic reticle is calibrated for 69-grain .223 Remington ammunition from a 14.5-inch barrel. Different TA33 models feature reticles optimized for specific cartridges, including 5.56 NATO, 300 BLK, and 7.62x39mm, each with corresponding bullet drop compensation.
Why is the reticle difficult to see in certain lighting conditions?
The dual-illuminated reticle automatically adjusts brightness through fiber-optic and tritium systems. In transition environments (from bright to dark), allow 1-2 minutes for your eyes to adapt to the tritium illumination. The fiber optic collector may need direct light exposure to function optimally.
Does the warranty transfer to second owners?
No, Trijicon's limited lifetime warranty applies only to original owners. Second-hand purchases are not covered under warranty, and tritium replacement becomes the new owner's responsibility. Always verify the manufacturer's date and warranty status before purchasing used units
