Description
Vector Optics SIG P226 Red Dot Mount, TEK (Docter/Noblex) - Black
The Vector Optics SCRDM-03 is a lightweight aluminium red dot mounting plate designed for SIG Sauer P226 pistols with a compatible standard rear sight dovetail. It uses the Vector Optics TEK footprint, corresponding to the widely used Docter/Noblex mounting standard. The plate allows compatible Vector Optics Frenzy and Sphinx sights, as well as other Docter/Noblex-pattern red dots, to be installed in place of the original rear sight without requiring an optics-ready slide.
Manufactured from 6061-T6 aluminium alloy with a matte black finish, the mount weighs approximately 16 g and is only 3 mm thick. Its low-profile construction keeps the optic close to the slide without adding unnecessary height or weight.
TEK Footprint - Docter/Noblex Compatibility
The SCRDM-03 uses the Vector Optics TEK footprint, which corresponds to the Docter/Noblex mounting standard. The mounting surface features four locating posts arranged in a rectangular pattern and two screw holes for securing the optic. The locating post spacing is 40 × 20 mm.
According to Vector Optics, the following red dot sights use the compatible TEK footprint:
- Vector Optics Frenzy FM SCRD-19II
- Vector Optics Frenzy FM SCRD-F19II
- Vector Optics Frenzy FM SCRD-G19II
- Vector Optics Frenzy FM SCRD-35
- Vector Optics Frenzy FM SCRD-40
- VictOptics SPX V3 RDSL16 and RDSL18
Vector Optics also lists the Sphinx SCRA-10A as compatible with this type of mounting plate.
The Docter/Noblex standard is also used by several other manufacturers, including compatible Docter/Noblex, Vortex Venom and Viper, and Burris FastFire sights. When using an optic from another manufacturer, check the exact footprint, locating post dimensions and mounting screw compatibility before installation.
Which Red Dot Sights Are Not Compatible?
Not all Vector Optics Frenzy sights use the same mounting footprint. The Frenzy product name alone does not guarantee compatibility with this plate.
The SCRDM-03 is not directly compatible with the following mounting standards:
- Trijicon RMR / SRO footprint - Vector Optics MOJ
- Shield RMSc / SMS footprint - Vector Optics MGT
- Aimpoint ACRO footprint - Vector Optics VOD
- C-More RTS / STS footprint - Vector Optics GIN
For example, Vector Optics Frenzy SCRD-36, SCRD-37 and SCRD-58 use the MOJ footprint and will not fit this plate. Frenzy-S SCRD-43 uses the smaller MGT footprint and is also incompatible.
Always check the exact model number and footprint of your red dot sight. A TEK/Docter-compatible optic is required for direct mounting.
SIG P226 Installation and Compatibility
The SCRDM-03 is designed to replace the original rear sight on a SIG Sauer P226 pistol. The factory rear sight must be removed before the adapter can be fitted into the rear sight dovetail.
The mounting plate is intended for compatible standard SIG P226 rear sight dovetails rather than factory optics-ready slide cuts. Vector Optics also confirms compatibility with standard SIG P229 slides that use the corresponding rear sight mounting arrangement.
This is a rear sight dovetail adapter, not a mounting plate for factory optics-ready slide cuts. SIG Sauer pistols can use different sight mounting arrangements depending on the model and slide version, so the original rear sight dimensions and construction must be checked before installation.
Airsoft SIG P226 Compatibility
The mounting plate was originally designed for real SIG Sauer firearms. Compatibility with airsoft P226 pistols is not guaranteed. Airsoft slides may use different rear sight dovetail dimensions, screws or proprietary mounting arrangements, even when their external appearance resembles the real pistol.
Installation on airsoft pistols may therefore require modification. This is particularly important on models where the rear sight is secured through the slide or forms part of the blowback unit mounting arrangement. Check the original rear sight construction and dimensions before purchasing.
