RTS3B-V3 High Performance Red Dot

The RTS3 is more than an upgrade — it’s a complete redesign engineered for maximum performance, durability, and reliability.

Prior to release, the RTS3 was extensively tested and competed with by shooting legends 10x World Champion Eric Grauffel, 4x World Champion Todd Jarrett, and 1x World Champion JJ Racaza.

The sight quickly proved itself by winning 1st Overall at the 2024 USPSA Carry Optics National Championship with Eric Grauffel.

The RTS3B-V2D continued that dominance by winning the 2025 IPSC World Shoot in Production Optics — Eric Grauffel’s 10th World Title — further cementing the RTS3 platform as one of the top-performing optics in the world.

Key Features

• Larger Performance-Coated Aspherical Lens – Delivers a clear, distortion-free sight picture for faster target acquisition and smoother transitions.
• Reinforced Aircraft-Grade Alloy Housing – Features an integrated base plate and reinforced construction for superior strength on slide-mounted applications.
• High-Performance Point Source LED – Provides ultra-high brightness with excellent efficiency and longer battery life. The emitter is protected by a tough LED shield to maintain consistent brightness over time.
• Hardened Electronics – Designed to withstand the recoil of the hottest large-caliber loads.
• Available Dot Sizes – 3 MOA, 6 MOA, or 9 MOA to suit any application from competition to defensive use.
• 1 MOA Click Adjustments – Precision internal locking screws deliver repeatable, pinpoint accuracy with no external locking screw required.
• IPX7 Waterproof – Fully sealed construction with O-ring protected battery tray.

V3 Upgrades

The new RTS3B-V3 builds on the proven RTS3B-V2D with important enhancements:

• New - DeltaPoint® Pro Footprint – Now compatible with both Deltapoint® Pro / SIG® PRO and standard C-MORE footprints.
• New - Fits ROMEO® 3 Max/XL Footprint – Shortened length on the rear of the sight to allow direct fit to Romeo 3 Max/XL slide cuts.

Brightness & Power Management

• Button Lockout Mode
• 12-position push-button intensity control with return-to-last-setting memory
• Brightness levels = 2 NV, 2 low light, 6 day light, and 2 super bright levels
• MSS – Motion Sensing System (Shake to Wake) – Automatically powers down to standby after 3 minutes of inactivity and instantly wakes with motion or vibration
• User-Programmable Auto-Off – Default is 4 hours of inactivity. Can be turned off to remain in Shake-to-Wake mode indefinitely.

Battery

Uses a common CR2032 lithium battery housed in a new aluminum battery tray. The tray allows battery changes without removing the sight from the firearm, eliminating the need to re-zero. The tray is O-ring sealed as part of the IPX7 waterproof rating.

Mounting

The RTS3B-V3 adds the DeltaPoint Pro (DPP) footprint and includes the dual pattern bottom plate. This allows direct mounting to slides and mounts using either the standard C-MORE pattern or the DeltapointV Pro (DPP) pattern, including SIG® PRO footprint.

Now fits SIG® ROMEO® 3 Max/XL slide cuts. (Shortened length on the rear of the sight to allow direct fit).

C-MORE mounting pattern is the same as the STS2 and RTS2 sights and has a 1.83" footprint (identical to the STS2). Because it is shorter than the RTS2, it is fully compatible with both STS2 and RTS2 mounts — it fits securely within the longer 2.00" RTS2 footprint.

Sights are shipped with the following components:

1 RTS3 Sight, 1 Protective Sight Cover, 1 CR2032 Battery (Installed), 1 Sight Adjustment Tool, 2x 8-32 Direct Mounting Screws w /Wrench,  2x M4 Direct Mounting Screws w /Wrench, 1 Instruction Manual, 1 Cleaning Cloth, 1 LensPen Micro.
