Holosun 509T Adapter Plate for Zev OZ9 and Brownells Glock Slides

Elevate your shooting experience with the Holosun 509T Adapter Plate, a meticulously engineered solution designed for the mounting of Holosun 509T optics onto the RMR footprint of standard ZEV Technologies Glock slides. This innovative adapter plate stands out from the competition, having been specifically crafted to work with slides that feature rear index posts and 4-40 screws. Compatibility extends to a range of models, including ZEV Glock slides, Brownells Glock slides, and P320 slides, ensuring that this adapter meets the needs of various firearm enthusiasts.

Robust and Lightweight Construction

One of the key features of the 509T adapter plate is its lightweight design, which is achieved through the use of high-strength billet 7075 aluminum. The plate’s underside is heavily relieved to minimize weight without compromising durability. This thoughtful engineering allows it to weigh less than half of comparable steel plates while providing the robustness needed for demanding professional and competitive shooting environments.

Designed with Holosun’s 45-degree dovetail mounting system and a recoil lug, this adapter plate provides secure and stable optics mounting. The 4-40 threaded post RMR cut ensures a perfect fit, reducing the chance of slippage or misalignment during critical moments of use.

Compatibility and Verified Fit

The Holosun 509T Adapter Plate has been tested and verified to fit a variety of popular models, including:

• All standard ZEV Tech slides, including Citadel, Hellbender, Duty, and Cryo slides, Gen3-5.
• Zev OZ-9 pistols.
• Zev P320 slides.
• Brownells Glock slides.
• Battlewerx slides featuring rear index posts and 4-40 screws.

Included with the adapter plate are two IP8 drive 4-40 screws, designed for easy installation on Zev Tech and Brownells slides. This plate comes with screws that utilize a Torx-Plus IP8 driver bit, which allows for a smaller overall head diameter, enhancing the aesthetic and functional profile of your setup.

Installation Considerations

For optimal installation, a torque-limiting screwdriver is highly recommended to ensure that the torque does not exceed the manufacturer’s specified limits. This will help maintain the integrity of your slide and ensure the longevity of your optics mounting.

Upgrade your firearm setup with the Holosun 509T Adapter Plate and experience the perfect combination of strength, precision, and lightweight design. Whether you’re a professional shooter or a dedicated enthusiast, this adapter plate is an essential component for mounting your Holosun 509T optics with confidence and reliability.

Notes:

The price difference from the Acro adapter plates is due to 7075 aluminum being roughly 2x more expensive than 6061, and is required for extra strength in the small areas of the dovetail.

Due to variances in Holosun’s production of the 509 optic, there may be some deformation of the adapter plate dovetail when tightening the optic past the recommended spec. This should not affect the performance, and could actually increase long term reliability due to minorly bedding in the optic and preventing any possible movement. All installation should be performed by a qualified gunsmith, and Dauntless Engineering is not responsible for damages due to incorrect installation or overtightening
