Frequently Asked Questions
Is the Trijicon ACOG 3x30 compatible with my AR-15?
Yes. The ACOG 3x30 (TA33) is designed to mount directly onto any standard flat-top AR-15, M4, or M16 with a Picatinny/MIL-STD-1913 rail. The included mount provides a co-witness-friendly height for use with or without backup iron sights. Always verify your specific upper receiver rail length before ordering.
Does the ACOG reticle work in total darkness?
Yes. The dual-illumination system combines a fiber optic collector (for daylight brightness) with a tritium phosphor lamp for low-light and nighttime use. The reticle glows automatically based on ambient light — no switches, no batteries, and no risk of the optic going dark at a critical moment. Tritium has an approximate 12-year half-life, so the glow will gradually dim over many years of use.
What does the Green Horseshoe/Dot reticle look like, and how do I use it?
The horseshoe is a large, open chevron-style circle that frames your target for rapid acquisition, while the center dot provides a precise aiming point at the intended zero distance (typically 100 yards for .223). Stadia lines below the dot correspond to bullet drop at extended ranges per the .223/5.56 ballistic trajectory, allowing holdover corrections without dialing turrets. This reticle is optimized for fast close-range shooting as well as precise longer-range engagement out to 600+ meters.
