Fast target acquisition, both eyes open

The Aim-O M2 is a 1x tube-style red dot built to the popular Micro pattern, giving you quick, both-eyes-open aiming for CQB and skirmish play. There is no magnification to slow you down, just a clear illuminated dot placed on target. It is one of the best value entry points into a proper reflex optic.

Red or green, five levels each

A rotary control selects between a red and a green dot with five brightness settings for each. Red suits most general conditions, green cuts through dark woodland and shade, and the brightness range covers everything from bright open days to dim indoor sites. You always have a dot that shows up against your background.

Built for the field

The housing is machined aluminium with a non-reflective black anodised finish, and it is splash-proof and fog-resistant so British weather and safe-zone condensation will not blind you mid-game. At roughly 300 to 310 grams complete with mount, it adds capability without unbalancing your replica.

The cantilever mount advantage

It ships on a cantilever L-mount that raises the sight line, which is a real benefit when you are running full-face protection or lower-sitting goggles. It clamps to any 20mm Picatinny, RIS or Weaver rail and runs on common 2x LR44 batteries. Browse more optics and rail gear in our airsoft accessories range.

Frequently asked questions

Does the mount raise the sight enough for a face mask or goggles?

Yes, that is the point of the cantilever L-mount. It lifts the optic to a higher, more natural sight line, which makes it far easier to get behind when you are wearing full-face protection or lower goggles. It clamps to any 20mm rail.

Red or green dot, which should I use?

Both are included on the same unit. A red dot is easy on the eye in most conditions, while green tends to pop against dark woodland or shaded backgrounds. Five brightness steps let you dial either colour up for bright days or down for indoor CQB.

What battery does it take and is it included?

It runs on 2x LR44 button cells. Whether batteries are pre-fitted varies by batch, so it is worth keeping a spare pair in your kit. They are cheap, common and last a long time on a 1x dot.

Will it survive being hit by BBs?

The body is full aluminium with a protected lens, and it is splash-proof and fog-resistant, so it stands up well to typical skirmish knocks and British weather. It is not a submersible or ballistic-rated optic, so treat direct lens hits with sense.

Does it fit my rifle?

It fits any 20mm Picatinny, RIS or Weaver top rail, which covers almost all airsoft AEGs, gas rifles and many pistols with a mounted rail. The cantilever mount clamps on with a screw fixing for a secure hold.
