Description
Specification

Fast target acquisition, both colours

The Aim-O M3 is a full-metal replica of the classic Aimpoint Comp-M3 red dot, built for quick, both-eyes-open shooting. Switch between a red or green dot and dial in one of five brightness levels per colour so the reticle pops whether you are in dark woodland or bright open ground.

Correct height, ready to shoot

The integral L-shaped high mount sets the optic at the right eye line for M4 and AR-platform replicas, so you snap onto the dot without hunting for it. It clamps securely to any 20mm Picatinny or Weaver rail with a screw-tightened base.

Built to take hits

The housing is CNC-machined from aluminium alloy with a matte, non-reflective finish that shrugs off skirmish knocks and will not flash and give your position away. Windage and elevation are fully adjustable to zero the dot to your gun.

Long runtime

Power comes from a single CR2032 coin cell tucked in the brightness dial, giving long life from a cheap, easy-to-find battery. Keep a spare with your other gear from our airsoft accessories range.

Who it suits

An ideal first optic or reliable backup for skirmishers who want fast CQB target acquisition without paying real-steel prices.

Frequently asked questions

Can I switch between red and green?

Yes. The rotary brightness dial cycles through 5 red levels and 5 green levels, so you can pick the colour and intensity that stands out best against your background and the light on the day.

What does the L-shaped mount give me?

The integral L-shaped high mount raises the optic to a comfortable, correct eye line on M4 and AR-platform replicas, so you can get behind the dot quickly without craning your neck. It clamps to any 20mm rail.

Which battery does it take?

A single CR2032 3V lithium coin cell, which sits in the brightness dial housing. It is a common battery and gives long runtime, so keep a spare in your kit.

Will it fit my rifle?

It mounts to any standard 20mm Picatinny or Weaver rail, which covers the vast majority of airsoft M4s, AKs with rail systems, and other rail-equipped replicas.

Is the body metal?

Yes. It is CNC-machined from aluminium alloy with a matte, non-reflective black finish that resists knocks and glare in the field.
