Aim-O Delta Type Open Red Dot — Black

The Delta Type is an open-frame red dot sight designed for RAS rail systems. Its compact profile makes it a practical choice for lightweight builds on carbines, airsoft rifles and training replicas, where target acquisition speed matters more than magnification.

The red dot offers 6 manually adjustable brightness levels, letting you match intensity to the environment: lower settings prevent blooming indoors or in low light, while higher levels keep the dot visible in direct sunlight without losing it in the field of view. Adjustment steps are evenly spaced with no sudden jumps, so the shooter can quickly dial in the right level without shifting focus from the target area.

Power comes from a single standard CR2032 battery, widely available anywhere. Switching off requires a 3-second press-and-hold: a deliberate design choice that prevents accidental shutdowns during weapon handling, but one that demands a conscious action at the end of a session. Shooters who prefer instant-off will find this trade-off less convenient; on the other hand, the risk of draining the sight from an unintended bump on the button is essentially zero.
