If you're upgrading your Glock 20 MOS and want the cleanest, most secure red dot solution — this is it.

These red dots are made to mount directly to your Glock 20’s MOS slide without an adapter plate. That means less bulk, better co-witnessing, and faster target acquisition with no extra hardware.

Whether you're building a duty pistol, a backcountry sidearm, or just want better optics for range days, a direct mount red dot is the most efficient upgrade for your Glock 20.

✅ Why Choose a Direct Mount Red Dot for Glock 20 MOS?

Glock’s MOS platform is designed for modularity, but most red dots still require an adapter plate to fit.

With a direct mount optic, you skip that step entirely. Here’s why it matters:

• No plate = fewer parts to fail

• Lower optic height improves sight alignment and co-witnessing

• Stronger mount — direct contact with the slide

• Smoother draw for holsters and better concealment

If reliability and simplicity are top priorities, direct mount is the way to go.
