Trijicon ACOG 3.5x35 Scope Red XHR Reticle .223
The Trijicon ACOG 3.5x35 Red XHR .223 is a battle-tested fixed-power riflescope engineered for shooters who demand peak optical performance and rock-solid reliability in every lighting condition — from bright daylight to complete darkness.
- 3.5x magnification with a 35mm objective lens for extended target acquisition
- Red XHR (Crosshair) reticle calibrated specifically for .223 / 5.56mm ballistics
- Dual-illumination system: fiber optic (daylight) and tritium (low/no light)
- Bullet drop compensated (BDC) reticle for accurate holds out to 800 meters
- Aircraft-grade aluminum alloy housing — waterproof, fogproof, and shockproof
- Both-eyes-open design for enhanced situational awareness in CQB environments
Who This Is For
The ACOG 3.5x35 is the go-to optic for AR-15 and M16-platform shooters who need a single optic capable of handling close-quarters engagements and precision shots at distance. It's equally at home on a duty rifle, a competition build, or a dedicated home-defense AR, and it's proven in the harshest operational environments on the planet. If you refuse to compromise between speed and accuracy, this is your optic.

Frequently Asked Questions
Is the Trijicon ACOG 3.5x35 compatible with my AR-15 or M4 platform?
Yes. The ACOG 3.5x35 is designed to mount directly on any Picatinny (MIL-STD-1913) or Weaver-style rail, making it fully compatible with AR-15, M4, and M16 platforms. The XHR .223 reticle is specifically calibrated for the ballistics of .223 Remington and 5.56x45mm NATO ammunition, so you get accurate BDC holdovers without any guesswork. Always confirm your mount or base is included or purchased separately, as some ACOG variants ship without a mount.
Does the ACOG require batteries to stay illuminated?
No — that's one of the ACOG's most distinctive advantages. The dual-illumination system uses a fiber optic collector on top of the scope to harvest ambient light during the day, automatically brightening or dimming the reticle as conditions change. At night or in low-light environments, a tritium lamp (with a rated 15-year service life) keeps the reticle visible without any batteries. This zero-battery-dependency design makes the ACOG uniquely reliable for extended field use.
What does the XHR reticle look like, and how does it differ from the standard ACOG chevron?
The XHR (Extra Heavy Reticle) features a thick crosshair design rather than the traditional chevron or triangle tip found on many ACOG variants. The heavier crosshair lines make it faster to acquire a sight picture in dynamic or close-quarters situations, while the BDC stadia lines along the vertical post allow precise holdovers at extended ranges. The red illumination provides strong contrast against most target backgrounds in daylight and twilight conditions, making it a versatile choice for both speed and precision shooting.
