What Is the Docter Footprint?
The Docter footprint (also called Noblex or Docter/Noblex footprint) is a standardized pattern of red dot sight mounting. Docter Optics (now Noblex) introduced it, and it has since become one of the most popular footprints in the micro red dot arena.
It features:
- Two mounting screw holes (in line)
- Four shallow recoil lugs (two front, two rear)
This design enables red dot sights to be directly clamped to a cut slide, mounting plate, or adapter of the same pattern.
Why Choose a Red Dot with a Docter Footprint?
A red dot that uses a Docter (Noblex) footprint is a good choice when you seek maximum compatibility, a low-profile installation, and when you want to have a large variety of optics available. This footprint was originally designed by Docter Optics, but is now one of the most prevalent mounting standards in the red dot market, particularly among micro red dots on pistols.
Key Reasons to Choose a Docter Footprint Red Dot:
- Widespread Compatibility
Many popular red dot producers, such as Vortex (Venom, Viper), Burris (FastFire), Leapers UTG, Noblex, and others, use the Docter footprint. This means:
- There is no requirement to change the mounting plate to change optics.
- A variety of handguns and adapter plates are already compatible with this footprint.
- Low Profile/Co-Witness Friendly
Docter footprint optics are mounted closer to the slide than something bulkier, such as RMRs. This enables:
- Improved iron sight co-witnessing
- Quicker acquisition of sight picture
- A smaller, snag-free configuration, particularly ideal in a concealed carry
- Time-tested and Trusted Design
It has a two-screw and four-recoil-lug mounting pattern, which offers a positive grip that is not readily displaced by recoil. It has been in the market for years and has proven to be effective in a shooting range of uses.
- Cross-Platform Flexibility
Docter footprint gives you flexibility when you are mounting a red dot to a pistol, shotgun, or rifle without being locked into proprietary mounts.
How to Mount a Docter Footprint Red Dot on Your Firearm
The procedure of mounting a red dot that has a Docter/Noblex footprint is quite easy, provided you have the correct setup. So here is a brief outline of the way it is done:
1. Verify Compatibility
Make sure your gun is either:
- Optics ready featuring a Docter footprint slide cut, or
- I have a mounting plate or adapter that allows the Docter footprint.
- A lot of pistols (e.g., Glock MOS, CZ P-10, Walther PDP) are supplied with replaceable plates.
2. Assemble the Appropriate Equipment
You’ll need:
- The mounting screws (often M3 or 6-32 screws) are included.
- Torque driver (to manufacturer spec, usually 10 -15 in-lbs)
- Thread locker (blue Loctite preferred)
3. Put in the Red Dot
- If a cover plate is present, remove it.
- Position the optic over the mounting holes.
- Install and torque the screws to requirement.
- Thread locker will help to keep them tight against recoil.
4. Confirm Zero
After mounting:
- Go to the range and sight in your red dot at your optimal distance (usually 1025 yards with pistols).
- Change elevation and windage as required (typically 1 MOA per click).
