C+H Optics MOS Adapter Plate For G17/G19 MOS
The C+H MOS Adapter Plate is designed for MOS optics-ready Glock models, offering compatibility with Trijicon RMR, SRO, and several Holosun models (407C/507C/508C/508T). The patented T-Nut mounting system provides six to seven threads of engagement, delivering enhanced security and reliability compared to standard plates. This plate targets MOS variants such as G17, G19, G22, G23, G34, G40, G41, G45, and G47, but will not fit non-MOS or slimline MOS versions.
Key features include a robust double-thread design for stronger engagement and broad optic compatibility, including RMR and SRO types. The USA-made build emphasizes durability under recoil, with a focus on secure zero retention. Installation requires standard caveats for MOS setups and precise alignment to ensure proper return-to-zero after disassembly.
C+H Optics MOS Adapter Plate For G17/G19 MOS (Second Variant)
This variant mirrors the first C+H MOS plate with similar MOS compatibility and optic options, including Trijicon RMR/SRO and Holosun models. It uses the patented T-Nut mounting system to enhance thread engagement, offering approximately double the threads of many competitors. The plate is engineered for reliable mounting on MOS-enabled Glocks, ensuring secure alignment with minimal risk of drift during use.
Users should verify that their firearm is MOS-equipped and compatible with the listed optics. As with other adapter plates, alignment and torque specification during installation are crucial for optimal sight picture and retention over time.
Osight RMR To RMSc Adapter Plate
The Osight RMR to RMSc Adapter Plate provides universal compatibility with RMSc and K footprints across multiple brands. Constructed from SUS420 stainless steel, it offers strong wear resistance and durability. The CNC-machined design plus PVD matte black coating provides a low-profile, corrosion-resistant mounting platform. Included screws and installation tools support straightforward installation, enabling precise alignment for repeatable accuracy.
Guardtier T10 Red Dot Mounting Plate
The Guardtier T10 mounting plate targets Glock MOS models and supports Holosun 407/507C/508T alongside Trijicon RMR/SRO. Crafted from precision 7075 aluminum with stainless steel hardware, this plate delivers a balance of strength and light weight. It is designed to fit MOS-configured Glocks (excluding slimmer 43X/48 MOS variants and aftermarket cut slides), providing a solid base for a reliable red dot setup under recoil.
TSA Adapter Plate For Glock MOS
The TSA Adapter Plate is designed for Glock MOS Gen 4/5 models, including a broad range of optics footprints such as RMR/SRO, Holosun 407C/507C/508T, ADE RD3, and more. CNC-machined from 7075-T6 aluminum, this plate emphasizes a high-strength fit, secure mounting, and compatibility resilience under varied recoil. It is not intended for slimline MOS variants like G43X or G48. A comprehensive mounting kit is included to facilitate installation and alignment.
DPP Titanium Mounting Kit For Glock RMR/SRO
The DPP Titanium kit is machined from 6AL4V aerospace-grade titanium, delivering a lightweight, super-strong mounting solution for RMR/SRO and Holosun 407C/507C/508T. The one-piece design promotes a secure zero hold, with a black finish that reduces glare. It is not compatible with counterfeit Trijicon RMRs. The titanium construction yields substantial weight savings while maintaining rigidity under recoil, appealing to shooters prioritizing low weight without sacrificing durability.
DAXISONN RMR Dovetail Adapter Plate
The DAXISONN RMR Dovetail Plate is designed for non-MOS Glock models and supports RMR, SRO, Holosun 407C/507C/508T and similar footprints. It is machined from 7075 T6 aluminum with hard-anodized coating for durability and corrosion resistance. The plate emphasizes compatibility with Glock lines that do not feature MOS, providing a secure interface for various red dot sights. It is not compatible with Glock MOS variants, Slimline models, or certain proprietary slides.
ohhunt RMSC To RMR Adapter Plate
The ohhunt plate converts RMSC footprints to RMR, enabling use with RMR footprint optics on RMS-cut slides. It is compatible with authentic RMR optics, including various Trijicon and Holosun models. The plate requires compatibility with X2-DB setups and accommodates slides with or without thread post features, delivering a flexible option for users transitioning to RMR optics.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm your firearm model (Glock MOS, non-MOS Glock, etc.) and the specific optic footprint (RMR, RMSc, SRO, Holosun 407C/507C/508T, etc.).
- Material and Finish: Aluminum (7075-T6) and titanium plates offer strong strength-to-weight ratios; stainless variants provide durability with different wear characteristics. Consider coatings (PVD, hard-anodized) for wear resistance.
- Engagement and Mounting: Look for multiple-thread engagement (e.g., 6-7 threads) for improved security. Ensure screws and a mounting tool are included if offered.
- Weight and Profile: Titanium plates are lighter; some plates emphasize ultra-low profiles to minimize holster fit issues and snag risk.
- Installation and Alignment: Check whether the kit includes installation tools, shims, or alignment aids. Proper torque and zero retention are essential for reliable performance.
- Non-MOS Considerations: If using non-MOS Glock or other brands, verify that the plate supports non-MOS dovetails and does not misfit generic slides.
- Brand and Warranty: Reputable brands with USA manufacturing or robust warranties can reduce risk of failure and misalignment over time.
In selecting an MOS-to-RMR adapter, balance the firearm model, the desired red dot footprint, weight considerations, and the intended shooting discipline. Evaluate whether you prioritize maximum strength (7075 aluminum or titanium), minimal recoil shift, or fastest installation. Consider reading user reviews about long-term retention, return-to-zero performance after field disassembly, and compatibility notes for specific optics to ensure the plate meets your needs.
