RTS3 Red Dot Sight

The RTS3 is more than just an upgrade—it’s a completely new design, engineered for maximum performance, durability, and reliability.

Prior to its market launch, the RTS3 underwent extensive testing and was used in competition by shooting legends such as 10-time world champion Eric Grauffel, 4-time world champion Todd Jarrett, and 1-time world champion JJ Racaza.

The sight immediately proved its worth with Eric Grauffel’s overall victory at the 2024 USPSA Carry Optics National Championships.

The RTS3B-V2D also continued this winning streak, winning the 2025 IPSC World Shoot in the Production Optics division—Eric Grauffel’s 10th world championship title. With this victory, the RTS3 platform definitively established itself as one of the highest-performing optics in the world.

Key Features

Larger performance-coated aspheric lens
Delivers a clear, distortion-free field of view for faster target acquisition and smoother target switching.

Reinforced aircraft-grade aluminum housing
Features an integrated baseplate and reinforced construction for maximum stability in slide-mounted applications.

High-Performance Point-Source LED
Extremely high brightness combined with efficient energy consumption and longer battery life. The emitter is shielded by a robust LED protector to ensure consistently stable brightness over time.

Reinforced electronics
Designed to withstand even the recoil of high-powered, large-caliber rounds.

Available dot sizes
3 MOA, 6 MOA, or 9 MOA—suitable for competition or defense applications.

1-MOA Click Adjustment
Precise internal locking screws allow for repeatable fine adjustments without external locking screws.

IPX7 waterproof
Fully sealed construction with an O-ring-protected battery compartment.

V2 Upgrades

The new RTS3B-V2D builds on the proven RTS3B-V1 and offers key improvements:

New dual-pattern base plate compatible with:

Standard C-MORE mounting diagram

DeltaPoint Pro (DPP) mounting diagram

Button lockout mode

Improved low brightness levels
For optimal performance in extremely dark conditions.

Brightness & Power Management

12-level push-button brightness control with memory function for the last setting used

2 night vision-compatible levels + 10 daylight levels

MSS – Motion Sensing System (Shake-to-Wake)
Automatically switches to standby mode after 3 minutes of inactivity and reactivates immediately upon detection of motion or vibration.

User-programmable auto-off
Set to 4 hours of inactivity by default. Can be disabled so that the visor remains in Shake-to-Wake mode permanently.

Battery

Uses a widely available CR2032 lithium battery in a new aluminum battery holder.

The battery can be replaced without removing the sight from the firearm—no need to re-zero. The battery holder is sealed with an O-ring and contributes to the IPX7 waterproof rating.

Mounting

The RTS3B-V2D uses the same mounting profile as STS2 and RTS2 sights and has a length of 1.83" (identical to the STS2).

Since it is shorter than the RTS2, it remains fully compatible with STS2 and RTS2 mounts and fits securely within the longer 2.00" RTS2 mounting slot.

The new dual-pattern baseplate allows for direct mounting on slides or mounts with:

Standard C-MORE pattern

DeltaPoint Pro (DPP) pattern

Package Contents & Mounting

RTS3B-V2D models come with direct-mount screws:

2× 8-32×9/16"

2× M4×14

Installation can be performed:

directly onto compatible slides

using a C-MORE mounting kit (sold separately)

or via aftermarket/custom mounts that meet C-MORE specifications.
