1x Reflex Optic: Fast, Both-Eyes-Open Shooting
A 1x red dot sight is all about speed and simplicity. With no magnification, you can shoot with both eyes open, keep full situational awareness, and focus on the target while the dot provides an easy aiming reference.
Why shooters love 1x red dot optics:
Faster target acquisition compared to traditional irons in many scenarios
Simple aiming concept—put the dot on target and press
Great for close to mid-range use depending on firearm and setup
Ideal for dynamic range drills, steel targets, and general practice
Helps newer shooters get confident with sight alignment faster
Whether you’re plinking, training, or setting up a dedicated range carbine, a 1x reflex optic is one of the most practical upgrades you can make.
30mm Tube with a 30mm Objective: Spacious Sight Picture
The 30mm tube / 30mm objective format offers a roomy sight window that many shooters find comfortable and quick to use. A larger objective can make it easier to:
Pick up the dot quickly during presentation
Track the dot during recoil and follow-up shots
Maintain a clear view of the target area
Feel less “tunnel-like” than smaller micro-style optics
For shooters who want a traditional tube-dot feel with a generous viewing area, 30mm is a classic, proven configuration.
3 MOA Dot: A Balanced Size for Speed and Precision
This optic uses a 3 MOA dot, a popular middle ground that balances quick acquisition with practical accuracy potential.
Why 3 MOA is a favorite:
Large enough to see quickly during fast shooting
Not so large that it overwhelms typical targets
Works well for general-purpose range use
Helps maintain a clean aiming reference at common distances
If you want an “all-around” dot size that fits a wide range of shooting styles, 3 MOA is a smart choice.
Red + Green Illumination: Match Your Dot to Your Environment
The NcStar DMRG130 features both red and green dot illumination, allowing you to pick what’s easiest to see based on lighting conditions and target/background colors.
Benefits of dual-color dots:
Better visibility options in bright sun vs. shaded areas
Ability to choose a dot color that contrasts your surroundings
Personal preference—some shooters see green more easily than red (or vice versa)
Flexible use across different firearms, ranges, and lighting environments
When your background changes—foliage, dirt berms, indoor backstops—having two colors can help you keep your dot easy to track.
Black Anodized Finish: Durable, Low-Glare Look
Finished in black anodizing, this optic is designed to hold up to normal range and field handling while maintaining a clean, low-glare appearance that pairs well with modern firearms.
Why anodized finishes matter:
Helps resist wear from regular handling and transport
Keeps a professional, understated look
Reduces glare in bright conditions compared to glossy finishes
Matches most black rails, mounts, and accessories
Great for Range Carbines, Shotguns, and Rimfire Builds
The NcStar 30mm red/green dot optic is a strong choice for:
AR-style range carbines and training setups
PCCs and lightweight plinking builds
Rimfire rifles used for practice and steel
Shotguns used for fast target acquisition at close distances
Shooters who prefer a traditional 30mm tube dot format
It’s an easy way to modernize your aiming system and get more out of every range session.
