My first impression of Trijicon ACOG 3.5x 35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope
The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope is an optic that needs little introduction. Trijicon‘s ACOG (Advanced Combat Optical Gunsight) series has a reputation for ruggedness, reliability, and battlefield-proven performance. I’d been running a traditional magnified optic on my .308 AR, but I wanted something more compact and quicker to acquire targets with at various distances, particularly within 500 meters.
I’ve always admired the ACOG’s simplicity and durability, but I was hesitant about the fixed magnification at first. However, the promise of a crystal-clear image, a bright reticle without batteries, and a ballistic drop compensator (BDC) specifically calibrated for the .308 cartridge piqued my interest. Unboxing the Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope, I immediately noticed the robust build quality.
The ACOG felt solid in my hands, noticeably more compact than my previous variable power scope. The included accessories – the flattop adapter, Scopecoat, LENSPEN®, lanyard, sticker, manual, and warranty card – added to the sense of value. I was cross-shopping this ACOG with a Leupold VX-Freedom and an EOTech Vudu, but I went with the Trijicon for its reputation for bombproof reliability and reticle clarity without the need for batteries. I was impressed with the initial feel and build.
Real-World Testing: Putting Trijicon ACOG 3.5x 35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope to the Test
First Use Experience
I tested the Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope at my local range and during a weekend hog hunt in central Texas. The range session focused on zeroing the optic and confirming the BDC at known distances, out to 600 yards. The hog hunt provided a more dynamic testing environment, with shots taken from various positions and under different lighting conditions.
The ACOG excelled in bright daylight, the fiber optic reticle glowing brightly. The green crosshair was easy to pick up against various backgrounds. I found the eye relief of 2.4 inches to be sufficient, though requiring a consistent cheek weld. After the first range session, I was very impressed with the sight picture.
Extended Use & Reliability
After several months of use, the Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope has proven to be incredibly durable. It has withstood a few bumps and scratches without losing zero. The finish shows minimal wear, even after being exposed to the elements.
Cleaning the lens is easy with the included LENSPEN®. I simply brush away any debris and then polish the lens with the cleaning tip. The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope outperforms any other optic I’ve used in similar conditions, especially in terms of its always-on reticle and ruggedness.
Breaking Down the Features of Trijicon ACOG 3.5x 35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope
Specifications
The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope features 3.5x magnification and a 35mm objective lens. The field of view is 28.9 feet at 100 yards. The eye relief is 2.4 inches, the length is 8 inches, and the weight is 14 ounces.
The reticle is a dual-illuminated green crosshair with a ballistic drop compensator (BDC) calibrated for the .308/7.62 cartridge. Adjustment size is 3 clicks per inch at 100 yards. These specifications contribute to the optic’s balance of magnification, field of view, and compact size, making it a versatile choice for a .308 platform.
Performance & Functionality
The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope performs exceptionally well in its intended role. The reticle is always illuminated, thanks to the fiber optic and tritium illumination, eliminating the need for batteries. This provides a clear aiming point in a wide range of lighting conditions.
The BDC is accurate when using .308 ammunition with similar ballistics to what the reticle was designed for, allowing for quick and easy target engagement at extended ranges. The fixed 3.5x magnification is a good compromise, providing enough magnification for longer shots while still allowing for relatively quick target acquisition at closer ranges. The only weakness is that very close range targets (under 25 yards) can be challenging without an offset red dot or canting the rifle. The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope meets and, in some cases, exceeds expectations.
Design & Ergonomics
The ACOG is known for its robust and simple design. The housing is made from forged aluminum, providing exceptional durability. At 14 ounces, it’s lightweight enough to not significantly impact the rifle’s balance. The compact size of the Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope also helps to maintain maneuverability.
The optic is user-friendly, with simple elevation and windage adjustments. There’s virtually no learning curve; mount it, zero it, and you’re ready to go.
Durability & Maintenance
The ACOG is built to last. Its rugged construction and lack of electronic components contribute to its exceptional durability. The tritium illumination is rated to last for many years, ensuring the reticle remains visible in low-light conditions.
Maintenance is minimal, requiring only occasional lens cleaning. The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope can be expected to provide years of reliable service with minimal care.
Accessories and Customization Options
The Trijicon ACOG 3.5x35mm Green Crosshair 308 / 7.62 BDC Reticle Rifle Scope comes with a flattop adapter for mounting on military-style rails. It also includes a Scopecoat for lens protection, a LENSPEN® for cleaning, a lanyard for the adjuster caps, a Trijicon logo sticker, an ACOG BAC manual, and a warranty card. While the ACOG itself has limited customization options, it is compatible with various aftermarket mounts for different rail systems and heights.
It’s also common to see ACOGs paired with offset red dot sights for close-quarters engagements, offering a more versatile sighting solution. Aftermarket lens filters and covers are available to further protect the optic.
