Delta Optical Compact Dot HD 28mm 2 MOA Red Dot Sight Weaver/Picatinny
The Delta Optical CompactDot HD 28 is a compact 1× red dot sight with a 28 mm objective, ideal for fast target acquisition in hunting and shooting applications where simplicity, speed and robustness matter.
It uses a single fixed dot size (2 MOA) with adjustable brightness levels, giving clear aiming without obscuring the target.
Features & Benefits
-
Large 28 mm Objective Window
Bright, clear view and good situational awareness at 1× — excellent for close to mid-range engagement. -
2 MOA Red Dot
Small dot size helps improve precision at moderate distances while still being fast to pick up with both eyes open. -
Adjustable Illumination with Brightness Control
Dot brightness can be adjusted over multiple steps to suit bright daylight or low-light conditions. -
Weaver/Picatinny Integrated Mount
Easy mounting on standard rails out-of-the-box without additional adapters. For other rails such as 11mm or 13mm adpater required. Ask us if unsure. -
Robust, Lightweight Build
Compact and portable at around 155 g and typical length ~70 mm — practical for rifles, shotguns and AR-type platforms. -
Waterproof & Durable Construction
Designed to withstand recoil and outdoor use. -
Japanese-Made Optics & Engineering
High-precision optical assembly and mechanical durability consistent with other Delta Optical products.
Best suited for:
-
Hunters and shooters wanting quick, intuitive aiming without fuss.
-
Rifles, shotguns or PCP/air rifles where a compact red dot improves speed of engagement.
-
Field shooters and driven hunt scenarios where eye-speed and situational awareness matter.
-
Plinking, small game and general shooting where fine precision is helpful but a reflex style sight is preferred.
Less ideal if:
-
You want variable dot sizes for different ranges (this model has a fixed 2 MOA). Or larger dot for short range fast/moving targets
-
You need advanced reticle shapes/holds — specialist reflex units with multi-reticle options are better.
-
Ultra-long-range precision beyond typical red-dot engagement ranges — scopes or magnified optics will suit better.
- Objective diameter: 28 mm
- Field of view: 12.2 m / 100 m
