Trijicon 6x48 ACOG Rifle Scope Matte, .308 Red Chevron Reticle with Picatinny Rail Adapter

The Trijicon 6x48 ACOG rifle scope is purpose-built for shooters who need magnified precision at extended range without sacrificing reliability or speed on target. This 6-power optic combines Trijicon's proven fiber optics and tritium illumination—no batteries required—with the red chevron reticle and Bindon Aiming Concept that have made the ACOG a standby for serious hunters and precision rifle competitors. The TA648-308 is calibrated specifically for .308 Winchester ballistics and includes a bullet drop compensator (BDC) with additional aiming points out to 1200 meters, so you can dial in holds for shots well beyond typical hunting ranges.

What sets the ACOG apart is its dual-illumination system: the chevron reticle glows in low light thanks to tritium, while natural and artificial light are amplified through the fiber-optic collector, giving you a bright, usable sight picture in nearly any condition. The 48mm objective gathers plenty of light, and the 3.3-degree field of view keeps distant targets crisp and centered. At 2.7 inches of eye relief, you get comfortable positioning and solid cheek weld, even on recoiling rifles. The forged aluminum housing is matte-finished and waterproof to 328 feet, built to handle harsh conditions without complaint.

The scope ships with a Picatinny rail adapter (TA75), a LENSPEN for keeping glass clean, a lanyard assembly for your adjuster caps, and a manual—everything you need to mount and use it right out of the box. This is a glass-and-steel optic for hunters and marksmen who value certainty over gadgetry: set it, forget it, and trust it to work.

The scope ships with a Picatinny rail adapter (TA75), a LENSPEN lens cleaning tool, a lanyard assembly for the adjuster caps, a Trijicon logo sticker, a user manual, and a warranty card.

What rifles is this ACOG calibrated for?

The TA648-308 is specifically calibrated for .308 Winchester and includes a bullet drop compensator with aiming points out to 1200 meters, estimated for the ballistics of the 7.62mm M80 cartridge.

Does the ACOG need a battery?

No. The reticle is illuminated by Trijicon's patented combination of fiber optics (which gather ambient light) and tritium (which self-illuminates in darkness). There is no battery to install, charge, or replace.

Is this scope waterproof, and will it work in bad weather?

Yes. The scope is waterproof to 328 feet and fully sealed against moisture and weather. The dual-illumination system—fiber optics for bright conditions and tritium for low light—works reliably in rain, fog, and near-dark hunting scenarios without any power source.
