AIM-O Multi Reticle Red/Green Dot

Most reflex sights give you a dot and that is the end of the conversation. A dot is the right answer indoors, where speed is everything and the target fills the window, and it is the wrong answer at the far end of a long lane, where a bare dot covers the thing you are aiming at.

This one carries four patterns and you cycle between them. A plain dot for room clearing, a circle-dot for a faster centre reference at mid distance, and crosshair patterns that give you something to hold over with when the BB starts dropping. Switching takes a second and does not move the zero.

Colour switches too. Red reads cleanly against foliage and dull daylight; green separates better from brown and orange leaf litter, which is most of a UK woodland site from October onwards. Five brightness steps cover a bright open field down to a dark building.

The housing is aluminium with multi-coated glass, a rubber cover in the box, and it clamps to any 20 mm rail. At 119 g it is light enough to sit on a pistol-calibre carbine without changing how the gun handles.

Good to know before you buy

Four patterns is useful and it is also four things to get wrong in a hurry. Pick the one you will use for the day in the safe zone rather than cycling mid-game.

The battery is not in the box. A CR2032 is a supermarket item, but it is worth having a spare in a pouch because the cell dying mid-game is the only real failure mode on a sight like this.

Coated glass means a slight tint to the view. On a clear day you will not notice; at last light through tree cover it is there.

Frequently asked questions

Which reticle should I start with?
The plain dot. It is the fastest to pick up and the least cluttered, and you can experiment with the others once the sight is zeroed and you trust it.

Red or green for UK woodland?
Green, usually. Autumn and winter ground is brown and orange, and a red dot sits closer to that palette than a green one does. Red is the better choice against grass and open sky.

Does changing the reticle shift the zero?
No. The patterns are projected onto the same optical centre, so the point of aim stays put.

Will it fit a pistol-calibre carbine or an SMG?
Yes. It clamps to a standard 20 mm rail and at 119 g it is light enough not to upset the balance of a short gun.

How do the crosshair patterns help?
They give you a reference below centre to hold over with as the BB drops, which a plain dot does not. At skirmish distances that is most useful past about thirty metres.
