Toni System Aluminum Red Dot Base Mount Plate (Type B) for Tanfoglio 1911 Witness
The Toni System Aluminum Red Dot Base Plate (Type B) is a high-precision optics adapter custom-engineered for Tanfoglio 1911 Witness pistols. This premium hardware component allows you to securely mount an electronic red dot sight directly into the factory rear sight dovetail slot, eliminating the need for expensive and permanent slide milling. It is the definitive upgrade for marksmen looking to update their classic 1911 platform for optics-ready competition divisions or to enhance target clarity in recreational shooting.
Precision CNC-machined from a solid block of aluminum, this adapter plate establishes a rock-solid, wobble-free interface with the slide. Utilizing high-strength aluminum keeps the accessory remarkably lightweight, preventing any added inertia that could disrupt the slide’s cycling timing, while providing excellent durability against continuous recoil shocks.

Technical Specifications & Key Features:
- Non-Destructive Drop-In Fitment: The base plate slides directly into the factory rear sight channel of the Tanfoglio 1911 Witness. The firearm can easily be reverted to its original factory configuration with iron sights at any time.
- Ultra-Low Profile Geometry: The mounting plate is calculated to position the red dot as close to the bore axis as possible, minimizing parallax error and ensuring natural, lightning-fast dot acquisition.
- Premium Material Build: High-grade billet aluminum treated with a protective matte black anodized surface finish to eliminate glare and resist handling wear.
Installation Guide: For a clean setup, a proper sight pusher tool should be used to remove the factory rear sight. Prior to final torque application on the mounting and optic hardware, applying a small drop of medium threadlocker is highly recommended to prevent any backing out caused by heavy rotational firing vibrations.
