The Trijicon ACOG 4x32 is the legendary battery-free combat optic — a fixed 4× prism scope that has served militaries and serious shooters for decades. Its genius is illumination with no batteries at all: fibre optics gather daylight and tritium glows in the dark, so the etched BAC .223/5.56 reticle is always lit and automatically matches the ambient light.
Because the reticle is etched into the glass, your aiming point is always there even without illumination — and the forged-aluminium housing is famously tough, waterproof and built to take a beating. This is the Crosshair reticle version with green illumination — often quicker to pick up in bright daylight and against foliage. In stock for fast UK dispatch.
Reticle Colour: Green — also available with Red illumination.

Frequently Asked Questions
Does the ACOG need batteries?
No — it is battery-free. Fibre optics power the reticle in daylight and tritium illuminates it in the dark, adjusting automatically to ambient light.
Why choose green illumination?
Green sits nearer the eye's peak sensitivity, so many shooters find it brighter in daylight and faster to pick up against foliage — see our green vs red guide.
What happens if the illumination fades?
The reticle is etched into the glass, so your aiming point remains fully usable even without illumination.
