DPP Titanium Rear Sight Dovetail Mount For RMR/SRO & Holosun
The DPP Titanium rear sight dovetail mount is precision CNC machined from 7075-T6 aluminum with black anodizing for corrosion resistance. It supports Trijicon RMR/SRO and Holosun 407C/507C/508T footprints, offering an ultra-low profile that preserves the pistol’s natural silhouette. The mount emphasizes strength, using 7075 aluminum to exceed common 6061 options while remaining lightweight. It is not designed for counterfeit Trijicon RMR units. Installation is straightforward for shooters looking to maintain a compact, reliable setup.
DPP Titanium Rear Sight Mount For Glock Venom & Viper
This mounting plate is designed for Glock variants and popular red dot options like Vortex Venom, Viper, Burris Fastfire, Docter, and Ade. Its ultra-low profile keeps the optic close to the slide, aiding speed and consistency. The one-piece design provides a secure zero hold, and the 30MOA elevation is intended to address optics with limited adjustment range. The solution is lightweight and easy to install, though it explicitly notes non-fit with counterfeit Venom variants.
DPP Titanium Rear Sight Dovetail Mount For Holosun 507K & Shield RMS
Engineered from 6AL4V aerospace-grade titanium with a black finish, this mount supports Holosun 507K, Shield RMS/RMSC, and Sig Romeo Zero footprints. The upgraded 30MOA design helps with higher mounting elevations, reducing gaps between the optic and the pistol mount. It includes installation hardware and is designed to maintain a rock-solid fit without shimming, ensuring a stable long-term zero for practical shooting or competitions.
DPP Titanium Rear Sight Mount For Venom, Fastfire & Docter (Version 3)
Version 3 features a sturdier dovetail and easier installation. Constructed from 6AL4V titanium with a black PVD finish, it supports 30MOA elevation and addresses common issues with insufficient optic elevation. The mount is designed to be robust while maintaining a slim, non-intrusive profile suitable for competition and range use.
Cross Armory Dovetail-to-RMSC Adapter
Cross Armory’s dovetail-to-RMSC adapter converts OEM Glock dovetails to the RMSC footprint for red-dot sights. Built from 17-4 stainless steel and CNC machined, it offers a drop-in fit with no milling required. It is compatible with many Glock non-MOS slides and preserves the slide’s geometry for reliable co-witnessing. The product includes a tall co-witness option and features a black nitride finish for durability and corrosion resistance.
DPP Titanium Rear Sight Dovetail Mount For Smith & Wesson M&P
Compatible with Trijicon RMR/SRO and Holosun 407C/507C/508T, this mount uses 6AL4V titanium with a black PVD finish. It’s designed for Smith & Wesson M&P non-optical-ready models, featuring a one-piece design for secure zero holds and simple installation. It also emphasizes a robust, lightweight profile suitable for ongoing use and competition.
Buying Guide
- Footprint compatibility: Ensure the mount matches your red dot’s footprint (RMR/SRO, Holosun 407C/507C/508T, RMS/RMSC, etc.) to avoid alignment problems.
- Material and finish: Titanium (6AL4V) and 7075-T6 aluminum offer strength with minimal weight. Black PVD or anodized finishes add corrosion resistance and durability in field conditions.
- Elevation and retention: Look for designed elevation options (30MOA) to address sights with limited up elevation. A secure one-piece design helps maintain zero under recoil.
- Installation: Preference for drop-in or simple mount-without-gunsmithing solutions reduces downtime and risk. Check included hardware and tools.
- Compatibility scope: Some mounts are tailored for specific Glock generations or other platforms; confirm slide compatibility (non-MOS vs. MOS, or specific compact frames).
- Warranty and support: A warranty (including money-back guarantees) provides recourse if the zero shifts or parts fail under normal use.
- Real-world use: Consider user feedback on zero retention under recoil, ease of installation, and how the mount affects concealment and draw time.
Why choose a premium dovetail red dot adapter?
Premium adapters combine robust materials, precise machining, and thoughtful design to preserve sight picture and accuracy. They reduce the risk of misalignment, improve elevation control, and maintain a compact silhouette that does not interfere with holster compatibility. For competitive shooting or personal defense, a reliable, well-supported adapter is essential to ensure quick and consistent target acquisition.
