OLIGHT Osight SE DPP 2/32 MOA – Enclosed Red Dot Sight with DPP Footprint
The OLIGHT Osight SE DPP 2/32 MOA is a compact enclosed red dot sight with a DeltaPoint Pro (DPP) footprint, designed for sport shooting, range training and demanding outdoor use. It combines a protected enclosed emitter, a selectable 2 MOA dot and 32 MOA circle reticle, 1× magnification, a side-loading CR1620 battery, and a lightweight CNC-machined 7075-T6 aluminium housing.
The enclosed design protects the emitter from rain, dust, mud and debris, making the Osight SE DPP a practical alternative to open-emitter reflex sights when environmental protection is important. At approximately 38 g, it remains compact and lightweight while offering the durability required for regular range sessions and outdoor use.
Optical Performance and Reticle
The OLIGHT Osight SE DPP uses a 1× parallax-free optical system with an aspherical, multi-coated lens and an approximately 23 × 18 mm viewing window. The 1× configuration provides a natural sight picture and supports both-eyes-open aiming, helping the user maintain awareness of the surrounding environment.
The red Multi-Reticle System (MRS) provides three selectable configurations:
- 2 MOA dot – a fine aiming reference for controlled shooting and precise shot placement.
- 32 MOA circle – a larger visual reference for faster reticle acquisition.
- 2 MOA dot + 32 MOA circle – combines the speed of the circle with the precision of the central dot.
This flexibility allows the reticle to be adapted to different shooting situations instead of relying on one fixed aiming point.
The sight provides 10 brightness levels, including 8 daylight settings and 2 night-vision-compatible settings. This allows the reticle intensity to be adjusted according to ambient light and background conditions.
Enclosed Emitter and Durable Construction
The enclosed emitter is one of the main advantages of the Osight SE DPP. Unlike an open-emitter reflex sight, the emitter is protected inside the optic housing, reducing the chance of rain, dust, mud or debris interfering with the projected reticle.
The housing is CNC-machined from 7075-T6 aluminium, combining high rigidity with low weight. The optic measures approximately 46.4 × 28.5 × 28.2 mm and weighs around 38 g, making it suitable for compact optic-ready setups where size and weight matter.
The IPX7 waterproof rating provides protection against water exposure, making the optic suitable for use in rain and wet outdoor conditions.
Battery, Memory Function and Motion Activation
The Osight SE DPP uses one CR1620 lithium battery installed in a side-loading battery compartment. This allows the battery to be replaced without removing the optic from its mounting position, helping avoid unnecessary reinstallation after the sight has been zeroed.
OLIGHT specifies a battery runtime of up to 75,000 hours when using the 2 MOA dot at brightness level 3. Actual battery life depends on brightness, temperature and usage.
The optic features Motion Activation and automatically enters sleep mode after approximately three minutes without movement. When movement is detected, it activates again.
A Memory Function remembers the previously selected brightness level, so the sight can return to the user's preferred setting after activation.
The Osight SE DPP also provides a low-battery warning. When battery voltage falls below the specified threshold, the reticle provides a visual warning to indicate that the battery needs to be replaced.
DPP / DeltaPoint Pro Footprint
The OLIGHT Osight SE DPP uses the DPP (DeltaPoint Pro) mounting footprint. This makes footprint compatibility an important consideration when selecting the optic for a particular platform.
On a platform with a native DPP optic cut, the sight can be mounted using the appropriate mounting hardware. Other optic-ready platforms may require a DPP-compatible adapter plate.
Before installation, check the compatibility of the specific optic-ready cut or mounting plate, as well as the required screws and installation specifications. The DPP footprint should not be confused with other OLIGHT Osight variants that use different mounting standards.
Recommended Applications
Sport Shooting and Range Training
The Osight SE DPP is suitable for regular range training and sport shooting where fast target acquisition and a clearly defined aiming point are important.
The 2 MOA dot is useful for controlled shooting and sight-in work, while the 32 MOA circle provides a larger visual reference that can be acquired quickly during dynamic drills. The combined reticle offers a practical balance between speed and precision.
Outdoor Use
For outdoor applications, the enclosed emitter provides an important advantage when the optic is exposed to rain, dust, vegetation and debris.
The combination of IPX7 waterproofing, compact dimensions and approximately 38 g weight makes the Osight SE DPP suitable for users who want additional environmental protection without adding a large or heavy optic to their setup.
The 1× optical system also supports a natural field of view and both-eyes-open aiming.
Low-Light Conditions
The 10 brightness levels allow the red reticle to be adjusted for changing light conditions, including shaded environments, wooded areas, indoor ranges and lower-light situations.
The optic provides 8 daylight settings and 2 night-vision-compatible settings, giving users more control over reticle visibility as ambient light changes.
Who Is the OLIGHT Osight SE DPP For?
The Osight SE DPP is a good choice for users looking for a compact enclosed red dot sight with a DPP footprint and selectable reticles.
It is particularly suitable for:
- Sport shooters who want both fast reticle acquisition and a precise central aiming point.
- Outdoor users who value an enclosed emitter and waterproof construction.
- Users moving from an open-emitter reflex sight who want additional protection from environmental exposure.
- Owners of DPP-compatible optic-ready platforms looking specifically for a DeltaPoint Pro footprint sight.
- Users who prefer low-maintenance equipment, thanks to motion activation, memory function, long claimed battery life and side-access battery replacement.
