Red Dot Sights

Red Dot Sight Selection Guide

A red dot sight projects an illuminated aiming point that appears on the target, so the user can aim with both eyes open and without lining up front and rear sights. JOVSTAR makes 1× red dot sights in full-size and compact formats, a 1× holographic sight with day and night vision modes, a 3× flip-to-side magnifier and a 1×/6× variable sight, all in IP67 sealed housings.

Choose a full-size red dot for the widest choice of reticles and a large window. Choose the compact red dot when weight and size matter most. Choose the holographic sight for a large window, a crisp reticle and night vision compatibility. Add the 3× magnifier behind a red dot or holographic sight for more detail at distance, or choose the 1×/6× sight when one optic must cover both close and mid range.

Values are each model’s stated specifications. See each product page for full details.

How Red Dot and Holographic Sights Work

Both types put an illuminated reticle in the user’s view, focused at a distance so it appears on the target rather than on the glass. They differ in how the reticle is made.

Reflex red dot sights

A small LED shines onto a curved lens with a coating that reflects the LED’s color and lets other light pass. The curve collimates the light, so the dot appears far away and stays on the target even if the eye moves slightly. LED sights use very little power: the JV-HRDS series and JV-ZS-01 are rated for ≥10,000 hours on one CR2032 cell.

Holographic sights

A holographic sight uses a laser diode to illuminate a reticle recorded as a hologram in the viewing window. The reticle stays sharp and keeps its shape across the window. The JV-HS-01 has a ≥28 × 18 mm window, parallax of ≤1.5′ and dedicated daytime and night vision modes. Holographic sights draw more power, so the JV-HS-01 uses AA batteries for ≥8 hours of continuous operation.

Magnifiers and variable optics

A magnifier such as the JV-TS-03 sits behind a 1× sight and enlarges both the target and the reticle 3×, then flips to the side when not needed. A variable optic such as the JV-ZS-01 builds both settings into one sight, switching between 1× with a 21° field of view and 6× with 3.5°.

Red Dot vs Holographic vs Magnified Optics

The right choice depends on distance, weight, battery life and whether the sight will be used with night vision.

• Red dot (reflex): light, simple and very efficient. The JV-HRDS series weighs ≤50 g and the JV-RDS-01 <150 g. Best for close-range use and for buyers who want long battery life.
• Holographic: larger window, a crisp reticle and night vision modes, at the cost of more weight (≤300 g with mount) and shorter battery life.
• Magnified: a 3× magnifier or a 1×/6× sight adds detail for observing and aiming at longer distances, with more weight (≤300 g and ≤465 g).

What to Compare When Choosing a Red Dot Sight

Most red dot sights look alike on paper. These are the specifications that separate them.

• Dot size (MOA). One minute of angle covers about 2.9 cm at 100 m. A small dot (1 MOA on the JV-RDS-01) covers less of a distant target; a large circle (30 MOA) is faster to pick up up close.
• Parallax. How far the dot appears to move against the target when the eye moves off-center: ≤1 MOA on the JV-RDS-01, ≤1.5′ on the JV-HS-01 and ≤2 MOA on the JV-HRDS series.
• Brightness and night vision modes. The dot must be bright enough in sunlight and dim enough not to flare at night or through night vision. The JV-HS-01 has dedicated night vision modes.
• Adjustment and zero retention. Adjustment range and click value set how precisely the sight can be zeroed: ≥±40 MOA in 0.25 MOA clicks on the JV-ZS-01 and ≥±10 mil on the JV-HS-01. Zero position variation after remounting is ≤1 mil on the JV-HS-01 and ≤1.8 MOA on the JV-RDS-01.
• Battery life. ≥10,000 hours on one CR2032 for the JV-HRDS series and JV-ZS-01, compared with ≥8 hours on AA batteries for the holographic JV-HS-01.
• Durability. All JOVSTAR sights are IP67. Shock ratings run from 1000 g on the red dots to 1200 g on the JV-ZS-01 and 1500 g on the JV-HS-01 and JV-TS-03, with 6061-T6 aluminum housings on the full-size models.

Mounting and Compatibility

The JV-HS-01 and JV-TS-03 weights include their mounting bases, and the JV-HS-01 uses interchangeable connectors for different platforms. The JV-TS-03 magnifier mounts on a Picatinny rail with a flip-to-side mount and has 60 mm of eye relief and -4 to +3 diopter adjustment, so it can sit behind a red dot or holographic sight and swing clear when not needed. The JV-ZS-01 has a 40.4 mm center height. When combining a sight and magnifier, check that the heights of the two optical axes match.

Red Dot Sight Applications

JOVSTAR sights are supplied to distributors and equipment makers for four main uses.

Sport and competition shooting

Fast, both-eyes-open aiming with a 1× red dot or holographic sight, with a magnifier for longer stages.

Hunting

A small dot for precise aiming in daylight and adjustable brightness for dawn and dusk; the JV-ZS-01 covers both close and mid range in one optic.

Night use with night vision

The JV-HS-01’s night vision modes keep the reticle visible through night vision devices without flare. See our night vision goggles range.

Private label and equipment programs

Distributors and equipment makers can source JOVSTAR sights under their own brand, with options for reticles, housings, finishes and packaging.
