Frequently Asked Questions
Is this ACOG specifically calibrated for .308 Winchester or 7.62×51mm NATO?
Yes. The Red XHR reticle in this ACOG variant is purpose-built with a bullet drop compensator (BDC) calibrated for .308 Winchester and 7.62×51mm NATO ballistics. The hash marks and stadia lines are designed to deliver accurate hold-over references out to extended distances using standard .308 load trajectories, making it an ideal choice for AR-10, SR-25, SCAR 17, and similar .308-platform rifles.
Does the Trijicon ACOG 3.5x35 require batteries to illuminate the reticle?
No — the ACOG's dual-illumination system uses a combination of tritium phosphor (for low-light and nighttime use) and a fiber optic cable that harvests ambient light during the day. This means the reticle is always illuminated and ready without any batteries, switches, or charging. It is one of the defining advantages of ACOG optics for field and tactical applications.
What mount or rail does this ACOG use, and is a mount included?
The Trijicon ACOG 3.5x35 is designed to mount on a standard MIL-STD-1913 Picatinny rail or STANAG 4694 rail. Depending on the specific SKU, a flattop or carry-handle mount may be included — always verify the package contents when ordering. Trijicon also offers a wide range of optional quick-detach and co-witness mounts compatible with this optic for AR-platform rifles and other .308 hosts.
