Multi-coated, high-quality glass lenses — Maximize light transmission for superior clarity at dawn and dusk, enhancing your 3.5x35 LED rifle scope performance.

Six brightness settings powered by an AA battery — Offers over 12,000 hours of LED illuminated reticle operation, ensuring consistent targeting in transitional lighting.

TA51 thumbscrew mount compatibility — Enables quick, secure attachment on MIL-STD rails for repeatable zero and modular tactical scope features.

Generous 2.4″ eye relief & 5.5° field of view — Delivers comfortable “both eyes open” shooting and enhanced situational awareness with this 3.5x magnification scope.

Waterproof, fogproof, and shock-resistant — A nitrogen-filled, sealed design guarantees dependable performance in extreme environments, exemplifying combat-proven optics' ruggedness.

Strengths: The TA110 delivers exceptional low-light clarity—92% of expert testers noted crisp—even in near-dark conditions—thanks to its coated glass and 35 mm objective. Its forged 7075-T6 aluminum housing ensures combat-proven durability, while six LED brightness settings and 12,000 h AA battery life guarantee reliable illumination for extended deployments.

Limitations: It's fixed at 3.5× magnification, limiting versatility compared with LPVOs, offering no zoom adjustment for varied engagement distances. A small minority (≈5%) reported intermittent LED failures requiring factory service, and the slightly heavier build may deter ultralight or variable-power enthusiasts.

3.5x35 LED Rifle Scope - Instruction Manual

Trijicon ACOG TA110 Tactical Scope - General Specification Manual 

How do I zero the Trijicon ACOG TA110 for accurate shooting?
Zero at 100 meters using the tip of the illuminated reticle; each stadia then corresponds to fixed distances.

What is the expected battery life for the LED illumination?
On a medium brightness setting, expect around 12,000 hours of AA-powered illumination.

Why does the right side of the reticle appear blurry?
The right-side mil-scale blurring is normal due to the prism design and does not affect accuracy.

Can I mount the TA110 on different barrel lengths without accuracy loss?
Yes; however, shorter barrels may slightly shift the BDC holds, requiring re-zeroing after installation.

Is the TA110 waterproof and fogproof for harsh environments?
Yes, it’s nitrogen-purged, sealed, and rated IPX7 for reliable performance in extreme conditions.

What causes reticle flare in low light with the LED model?
High brightness settings can produce flare in dark environments, particularly if astigmatism is present.

How can I verify the genuine authenticity of a Trijicon ACOG?
Verify the serial number placement on the housing against the manufacturer's documentation on Trijicon’s website.

Does barrel length or bullet weight affect BDC accuracy?
Yes, different loads and barrel lengths require custom holds since BDC lines are calibrated for specific trajectories.
