How to Mount Your Red Dot Optic

Required Tools & Materials:

• Torx T10 screwdriver (usually included with MOS kit)
• Blue Loctite 243 (recommended)
• Torque wrench (10–15 in/lbs recommended)
• Optic-specific mounting screws (often included with optic)

Step-by-Step MOS Installation:

1. First, remove the MOS cover plate using the T10 screwdriver by backing out the two retaining screws.
2. Next, identify the correct MOS adapter plate for your specific optic model from the included plate set.
3. Then, attach the adapter plate to the slide using the provided screws with a small drop of Blue Loctite on each thread.
4. After that, mount your red dot optic to the adapter plate, torquing all screws to the optic manufacturer’s specifications.
5. Finally, apply witness marks to all screws and perform an initial bore-sight or live-fire zero at your intended distance.

Pro Tips for MOS Installations:

• Always verify your optic is compatible with the standard full-size MOS footprint before ordering adapter plates
• Replace MOS screws if they show any signs of thread damage or stripping
• Check optic screw torque every 200–300 rounds during initial break-in, then every 500 rounds thereafter
• Consider co-witness or suppressor-height sights as an upgrade for iron sight backup with your red dot

Fit and Compatibility

Compatible with This MOS Slide:

• Glock 17 Gen 5 frames (all variations including MOS and standard)
• Aftermarket Gen 5 G17-compatible frames
• All major red dot optics via MOS adapter plate system (RMR, DPP, Romeo1, Venom, DeltaPoint Pro, and more)
• OEM Gen 5 internals and factory-specification aftermarket components

NOT Compatible with This MOS Slide:

• Glock 17 Gen 1, Gen 2, Gen 3, or Gen 4 frames (different rail and component specifications)

Care and Maintenance Guide

nDLC Finish Care – The nDLC finish is among the most durable available on any production pistol slide. Clean with a soft cloth and quality solvent. Unlike traditional finishes, nDLC resists fingerprints, fouling, and corrosion exceptionally well, requiring minimal maintenance to maintain its appearance and protective qualities.

MOS Plate and Optic Interface – Periodically remove the optic and clean the interface between the adapter plate and slide. Specifically, carbon fouling and debris at this interface can affect zero retention and optic stability over time. Furthermore, inspect adapter plate screws for wear after every cleaning.

Optic Screw Maintenance – Check optic mounting screw torque every 500 rounds under normal use. Additionally, during high-volume range sessions or competition use, verify torque more frequently. Always re-apply Blue Loctite if screws are removed and reinstalled.

Gen 5 Recoil Spring Maintenance – The Gen 5 dual recoil spring assembly should be inspected regularly and replaced every 5,000 rounds for optimal carry reliability. Moreover, a worn recoil spring can cause cycling issues that affect both reliability and accuracy.

Striker Channel Cleaning – Regularly clean the striker channel to prevent carbon and primer residue buildup. Consequently, a clean striker channel ensures consistent primer ignition and reliable function across all ammunition types.

Barrel Maintenance – If running the complete assembly, clean the Marksman barrel after every range session. Thus, consistent bore maintenance preserves the enhanced accuracy the Gen 5 Marksman barrel is specifically designed to deliver.
