Who This Is For
The Trijicon ACOG 3.5x35 HS .308 is purpose-built for serious .308/7.62x51mm shooters — including hunters, competitive marksmen, and defensive rifle owners — who demand a zero-battery, always-ready optic that excels from room distance out to several hundred meters. It's an ideal upgrade for AR-10, DPMS, SR-25, and similar .308 platforms running a standard Picatinny rail.

Frequently Asked Questions
Is this ACOG compatible with my .308 AR-10 or DPMS-pattern rifle?
Yes. The Trijicon ACOG 3.5x35 HS .308 (TA11H-308) is specifically calibrated for .308 Winchester / 7.62x51mm NATO cartridges and ships with the TA51 flattop mount, which attaches directly to any standard Picatinny (MIL-STD-1913) rail. It is compatible with AR-10, DPMS, SR-25, SCAR 17, and similar .308 platforms without additional adapters.
Does this ACOG require batteries to illuminate the reticle?
No batteries are required. The ACOG uses a patented dual-illumination system: a fiber optic collector automatically adjusts reticle brightness in daylight conditions, while a tritium phosphor lamp provides hands-free illumination in low-light and no-light environments. This makes the optic always operational regardless of battery availability.
What does the Horseshoe (HS) reticle offer compared to a standard crosshair?
The Horseshoe reticle features a bold open-circle aiming point at center — fast to acquire under stress — combined with calibrated stadia lines below for bullet drop compensation (BDC) out to approximately 800 meters with .308 Win / 7.62x51mm ammunition. It also supports ranging estimation for man-sized targets, making it significantly more versatile than a traditional duplex or mil-dot reticle for real-world field use.
