A UK-based specialist retailer of premium optics and tactical gear from trusted global brands — with no import fees and secure checkout.
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, offered with red or green illumination. In stock for fast UK dispatch.

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.
What is "BAC"?
The Bindon Aiming Concept — the bright reticle encourages both-eyes-open shooting for very fast target acquisition, while the BDC element is calibrated for .223/5.56.
What happens if the illumination fades?
The reticle is etched into the glass, so your aiming point remains fully usable even without illumination.
What's the difference between the red and green versions?
Illumination colour only — choose whichever your eye picks up faster.
Does it come with a mount?
Yes — it includes a Trijicon mount; reticle options also include Horseshoe/Dot and Chevron versions.
