Reactive shooting, sorted

The Aim-O EXPS holo hybrid sight is built for fast, reactive shooting on airsoft rifles. Its projected reticle lets you snap onto targets with both eyes open, making it a superb close to mid-range optic for skirmishers who value speed. The raised profile gives a natural, heads-up sight picture that many players find quicker to acquire.

Red or green at the push of a button

A single NV button toggles the reticle between red and green, while dedicated up and down buttons adjust brightness. That makes it easy to keep the aiming point crisp whether you are pushing through dark buildings or holding an open lane in daylight.

Magnifier-ready and rail-friendly

The EXPS sits slightly higher than the 551 and works well with a G43 or G33-style flip-to-side magnifier for added reach. A QD lever locks and releases it from any 20mm Picatinny or RIS rail without tools, fitting virtually all AEGs. Browse more airsoft accessories to build out your rifle.

Solid build, simple upkeep

A heavyweight metal mount base and removable metal lens hood give the sight a reassuringly rugged feel, and horizontal and vertical dials make zeroing straightforward. The front-access battery compartment takes a single CR123A cell, so power changes are quick and hassle-free.

Frequently asked questions

How does the EXPS differ from the 551?

The EXPS/558 sits slightly higher than the 551 and older AA-powered 558, giving a raised, comfortable sight picture that pairs neatly with a magnifier.

Can I switch the reticle colour?

Yes. A single NV button toggles the reticle between red and green, while the up and down buttons adjust brightness to suit the light.

Does it work with a magnifier?

It does. It pairs well with a G43 or G33-style flip-to-side magnifier (sold separately) for fast close-range aiming plus extra reach.

How does it mount?

A QD lever locks and releases the sight from any 20mm Picatinny or RIS rail with no tools, fitting virtually all AEGs with a 20mm rail.

What battery does it use?

It runs on a single CR123A battery accessed through the front battery compartment, so you can swap cells without removing the optic.
