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 with red illumination. In stock for fast UK dispatch.
Reticle Colour: Red — also available with Green 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.
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.
Does it come with a mount?
Yes — it includes a Trijicon mount; reticle options also include Horseshoe/Dot and Chevron versions.
