DPP Titanium Rear Sight Dovetail Mount for Glock (RMR/SRO, Holosun)
This mount is crafted from 7075-T6 aerospace-grade aluminum, offering a stronger alternative to common 6061 builds. Its ultra-low profile preserves the pistol’s natural sight picture while adding a secure plate for popular red dot footprints. The design specifies compatibility with Trijicon RMR/SRO and Holosun 407C/507C/508T, with a note that it does not fit counterfeit RMR units. Lightweight construction and precise CNC machining contribute to a consistent zero and reliable performance under field conditions.
DPP Titanium Dovetail Mount for Glock Vortex/Venom & Viper
This mounting plate emphasizes an ultra-low profile and lightweight construction for a secure, reliable zero. It’s designed for Glock-compatible red dots like Vortex Venom and Viper, as well as Burris Fastfire and Docter ADE. The one-piece design aids straightforward installation and zero retention. The adapter features a 30MOA elevation option to ensure adequate sight alignment, addressing common issues with insufficient elevation on some red dots.
DPP Titanium Dovetail Mount for Glock Holosun 507K & Shield RMS
Engineered from 6AL-4V aerospace-grade titanium with a black finish, this adapter supports Holosun 507K and Shield RMS/RMSC footprints. The updated 30MOA design resolves elevation limitations for down-mounting sights on pistol slides. The one-piece construction ensures a secure zero hold, and installation hardware is included for a straightforward setup, enabling a solid, repeatable shooting platform.
DPP Titanium Dovetail Mount for Glock Vortex/Venom & Burris Fastfire
The third-generation version strengthens the dovetail for easier installation and a firmer hold. Made from 6AL-4V titanium with a black PVD finish, it employs a 30MOA design to accommodate additional elevation adjustment. This model notes compatibility with Venom/Viper and Burris Fastfire, while explicitly stating non-fit with Venom Enclosed designs. A robust solution for shooters seeking a lightweight, reliable mounting option.
Cross Armory Dovetail-to-RMSC Adapter (Glock)
Constructed from 17-4 stainless steel and CNC-machined for precision, this adapter converts OEM Glock dovetails to the RMSC footprint. It’s designed for a broad range of Glock slides (Gen 3–5) and uses a drop-in fit that installs quickly without milling or gunsmithing. The tall co-witness design blends rear iron sight with a green fiber-optic front sight, maintaining a familiar silhouette while enabling modern red-dot use. Black nitride finish provides wear resistance for long-term use.
DPP Titanium Dovetail Red Dot Mount for Smith & Wesson M&P
This mount combines 7075-T6 aluminum construction with a black anodized finish and a 30MOA elevation design, tuned for RMR/SRO and Holosun 407C/507C/508T footprints. The one-piece design ensures a secure zero, with a strong emphasis on compatibility with Smith & Wesson M&P models that are configured for non-optical-ready frames. The adapter is designed to be lightweight and straightforward to install, offering a reliable platform for a variety of red-dot configurations.
Buying Guide: Key Purchase Considerations
Material and strength: Titanium and aerospace-grade aluminum (7075-T6) offer high strength-to-weight ratios, resisting deformation under recoil. Titanium is typically more corrosion-resistant and lighter but comes at a higher cost. Evaluate whether you need maximum strength or budget-friendly lightness for your build.
Elevation and zero retention: Many adapters feature 30MOA elevation to address limited sight adjustment on some pistols. If your current red dot sits high or low on the mount, a 30MOA design can help achieve proper point-of-aim without compromising reliability.
Compatibility footprint: Ensure the adapter supports your specific red dot footprint (RMR, SRO, RMSc, Holosun 407C/507C/508T, Shield RMS/RMSC, Burris Fastfire, etc.). Some mounts list “not for counterfeit” or “not for Venom enclosed”; verify your exact sight version before purchasing.
Installation and fit: Look for one-piece designs that reduce slippage and simplify installation. A straightforward, gun-sling-free setup minimizes the risk of misalignment. Some adapters require no gunsmithing or milling, which saves time and preserves firearm warranties.
Profile and silhouette: A low-profile mount preserves the original sight radius and keeps the slide’s silhouette consistent. This can aid in accuracy and speed, especially in competition or duty carry scenarios where drawing and target acquisition matter.
Warranty and support: A clear warranty, including money-back or lifetime coverage, signals manufacturer confidence in the product’s durability. Read the terms to understand what qualifies as a warranty claim and the return policy.
Final considerations: When choosing, match the mount material, elevation needs, and footprint compatibility to your pistol model and preferred red-dot sight. Always follow safe firearm handling practices and verify fitment with a professional if you are unsure about installation or compatibility.
