The Trijicon ACOG 4x32mm with Green Chevron Reticle, model 100229, stands as a benchmark in combat optical design. KFF Defense provides this internally-adjustable, compact telescopic sight for operators demanding unflinching reliability and precise target engagement across diverse operational environments. Engineered to integrate seamlessly with the M16 family of rifles, its design prioritizes mission success without reliance on external power sources or fragile components.
Key Features
Optical Performance
The ACOG 100229 features a fixed 4x magnification with a 32mm objective lens, providing a balanced field of view and target identification capability. Incorporating the Bindon Aiming Concept (BAC), the optic facilitates rapid target acquisition through a bright, daylight-illuminated reticle. This system leverages fiber optics to collect ambient light, ensuring the reticle remains highly visible without wash-out, critical for maintaining situational awareness during dynamic engagements.
Illumination System
A distinct advantage of the ACOG platform is its dual-illumination system. The Green Chevron reticle is powered by a combination of a tritium phosphor lamp for low-light and night operations, and a fiber optic light collector for daytime brightness. This fully passive, battery-free illumination ensures continuous reticle visibility, eliminating power source failures that plague lesser optics in critical scenarios. The chevron reticle offers a precise aiming point for both close-in engagement and extended-range marksmanship.
Robust Construction
The ACOG 100229 is built to withstand extreme conditions. Its housing is precisely machined from a single piece of forged 7075-T6 aircraft-grade aluminum alloy, then finished with a Mil-Spec hardcoat anodization for superior resistance to abrasion and corrosion. Internally, the optic is nitrogen-filled to prevent fogging and is waterproof to 100 meters (330 feet). This construction ensures consistent performance and zero retention under severe shock, recoil, and environmental exposure.
Precision Engineering
Equipped with internally-adjustable windage and elevation, the ACOG 100229 allows for precise zeroing and corrections. Each adjustment click provides 1/2 MOA of movement, facilitating fine-tuned ballistic compensation. The integrated TA51 mount ensures a secure and repeatable attachment to Picatinny rails, maintaining integrity under sustained fire and harsh use.
