This guide details the process of mounting a Vortex Defender XL red dot sight onto a Glock 47 MOS pistol using an Arise Manufacturing Low Rider plate. It emphasizes the importance of using a torque wrench for proper screw tension, applying blue Loctite to prevent loosening, and performing witness marks to monitor the optic's security. The instruction is provided by Joel Park, who has extensive experience with Ben Stoeger's firearms.

Quick Summary

To securely mount a red dot optic on a Glock 47 MOS, use blue Loctite on all screws and tighten them to the manufacturer's specified torque, typically around 14-15 inch-pounds, using a torque wrench. Witness marks should be applied to screws to easily detect any loosening over time. Allow Loctite to cure fully before extensive use.

Frequently Asked Questions

What is the recommended torque setting for mounting a red dot optic on a Glock 47 MOS?

For mounting optic plates and the optics themselves on a Glock 47 MOS, the recommended torque is typically around 14-15 inch-pounds. It's crucial to use a torque wrench and adhere to the specific recommendations from the optic and plate manufacturers to avoid damaging components.

What type of Loctite should be used when mounting a red dot sight on a firearm?

Blue Loctite, such as Loctite 242 or a Loctite stick, is recommended for mounting red dot sights and their plates. This provides sufficient hold to prevent loosening from recoil but allows for disassembly without excessive force or heat, unlike red Loctite.

How do you ensure a red dot optic stays securely mounted on a Glock MOS system?

Security is achieved through proper installation techniques: using blue Loctite on screws, tightening them to the manufacturer's specified torque with a torque wrench, and performing witness marks to easily detect any loosening over time. Allowing the Loctite to cure fully is also critical.

What is the purpose of witness marks when installing a red dot sight?

Witness marks are lines drawn from a screw head to the surface it's mounted on (like the optic housing or mounting plate). They serve as a visual indicator to quickly check if a screw has backed out or loosened due to recoil, ensuring the optic remains securely attached.
