Hey guys! Ever found yourself in a bit of a pickle, trying to mount an optic on your favorite handgun and realizing the footprints just don't match up? Well, you're not alone! Many of us have faced the frustrating situation where our desired optic's footprint doesn't jive with our slide's pre-cut pattern. Today, we're diving deep into a handy solution to this problem: the Doctor Footprint to RMR Adapter. We'll cover everything, from what these adapters are, why you might need one, and how to choose the right one, to installation tips and some common FAQs. Let's get started!

What is a Doctor Footprint to RMR Adapter?

So, what exactly is this magical adapter? Simply put, a Doctor Footprint to RMR Adapter is a small, precision-engineered plate designed to bridge the gap between two popular optic mounting standards: the Doctor (Docter/Noblex) footprint and the Trijicon RMR footprint. Confused? Let me break it down. The footprint refers to the pattern of screw holes and mounting features on the slide of your handgun, or on the adapter plate itself, which is what the optic is mounted on. The Doctor footprint, often found on optics like the Docter, Noblex, and some Vortex models, features a unique hole pattern. The Trijicon RMR (Ruggedized Miniature Reflex) footprint, on the other hand, is one of the most widely adopted standards in the pistol optic world, known for its robust design and compatibility with a vast array of optics, including the ever-popular Trijicon RMR itself. So, if you have a slide cut for a Doctor footprint, and you want to mount an optic with an RMR footprint (or vice-versa), this adapter is your new best friend. It essentially acts as a middleman, allowing you to mount an optic with one footprint onto a slide designed for the other. These adapters are typically made from durable materials like aircraft-grade aluminum or steel, ensuring they can withstand the recoil and abuse that comes with shooting. This guarantees reliability and longevity, making sure your optic stays securely mounted, shot after shot. These adapters often include the necessary screws for installation, making the process as straightforward as possible. Choosing the correct adapter is crucial for the proper and secure mounting of your optic. Always double-check the specifications of your slide and optic to guarantee compatibility.

Why Use an Adapter?

Now, you might be wondering, why not just get a slide cut specifically for the RMR footprint? Well, there are several reasons why a Doctor Footprint to RMR Adapter might be the perfect solution for you:

• Cost-Effectiveness: Getting a slide milled or buying a new slide can be expensive. An adapter is a far more affordable option, allowing you to use the optic you want without breaking the bank. It is cost-effective since it is an accessory and its value is lower than a slide milling.
• Flexibility: Adapters offer flexibility in terms of optic choices. You're not locked into a single footprint. You can easily switch between different optic models that use the RMR footprint without modifying your slide. This also allows you to test out different optics before committing to a permanent slide modification.
• Convenience: The process of installing an adapter is generally quick and easy, requiring minimal tools and expertise. This is great for those who don't want to deal with the complexities of slide modifications or sending their slide off for milling. This is a simple plug-and-play solution.
• Preservation of Value: Keeping your original slide intact can preserve the resale value of your firearm. Slide modifications can sometimes reduce the value, so using an adapter can be a smart move if you might consider selling your gun down the road.
• Availability: RMR footprint optics are very popular, but you may have a Doctor footprint slide. The adapter expands your optic choices greatly.

Choosing the Right Adapter

Alright, so you're sold on the idea of using a Doctor Footprint to RMR Adapter. Awesome! But how do you choose the right one? Here's what you need to consider:

• Footprint Compatibility: This is the most crucial factor. Double-check that the adapter is specifically designed to convert from the Doctor footprint to the RMR footprint. Make sure it's the right fit.
• Material: Look for adapters made from high-quality materials like aircraft-grade aluminum or steel. These materials are durable and can withstand the recoil of your handgun, ensuring your optic stays secure.
• Finish: The finish of the adapter is also important. A good finish will protect the adapter from corrosion and wear. Options include anodized finishes, which provide a durable and aesthetically pleasing coating. Also, consider options like Cerakote for an ultra-durable finish.
• Height/Thickness: Consider the thickness of the adapter. Some adapters are designed to sit flush with the slide, while others may raise the optic slightly. Choose an adapter that provides the desired sight picture and allows for proper co-witnessing with your iron sights if that's a priority. Keep in mind the height, and how it will affect your ability to get a good sight picture, the higher it is, the harder it is to get a good sight picture.
• Screw Quality: The screws included with the adapter should be high-quality and properly sized for your optic and slide. Check the material and thread pattern. Stainless steel screws are a good choice for corrosion resistance. Make sure you use the right tools when installing to avoid stripping the screws.
• Brand Reputation: Research the brand and read reviews. Look for reputable brands known for producing high-quality and reliable adapters. Brands with good customer feedback are often a safe bet. Take a look at the ratings and make a good decision based on this.
• Ease of Installation: Consider the installation process. Look for adapters that are easy to install and come with clear instructions. Some adapters may require specialized tools, so make sure you have everything you need before you start.

Installation Guide: Doctor Footprint to RMR Adapter

Installing a Doctor Footprint to RMR Adapter is generally a straightforward process. But always refer to the specific instructions provided with your adapter. However, here's a general guide to get you started:

1. Preparation: Gather your tools: You'll typically need a set of Allen wrenches or a Torx wrench (depending on the screws included with the adapter), a torque wrench (highly recommended for precise tightening), and a clean workspace. Make sure you have a clean workspace and good lighting.
2. Remove the Slide: Field strip your handgun and remove the slide from the frame. This allows for easier access to the mounting surface.
3. Clean the Slide: Clean the mounting surface of your slide thoroughly. Remove any dirt, debris, or old thread locker. A clean surface ensures a proper fit.
4. Install the Adapter: Place the adapter onto the Doctor footprint cut on your slide. Ensure it fits flush and aligns with the screw holes. Check the fit; it should be secure.
5. Install the Optic: Place the optic onto the RMR footprint on the adapter, aligning the screw holes.
6. Tighten the Screws: Using the appropriate Allen or Torx wrench, tighten the screws. Important: Use a torque wrench and follow the manufacturer's recommended torque specifications for both the adapter-to-slide and optic-to-adapter screws. Over-tightening can damage the adapter or your optic, while under-tightening can cause the optic to come loose under recoil. Apply thread locker if recommended by the manufacturer. Follow torque specs to the letter, a good set of torque wrenches will go a long way.
7. Final Checks: After installation, double-check that all screws are securely tightened and that the optic is properly aligned. Shake the slide to ensure nothing is loose. Verify your zero at the range before you consider the job complete.

Frequently Asked Questions (FAQs)

Let's tackle some common questions about Doctor Footprint to RMR Adapters:

• Q: Will this adapter affect my gun's accuracy?
  • A: If the adapter is properly installed and torqued to the manufacturer's specifications, it should not negatively affect your accuracy. Accuracy is more dependent on the quality of your optic, your shooting skills, and the stability of the mounting system. The adapter itself, when used correctly, will not cause any problems.
• Q: Can I use this adapter with any Doctor footprint optic?
  • A: Not necessarily. While the adapter is designed to work with Doctor footprint slides, some variations exist in the Doctor footprint itself. Always double-check the specific dimensions of your optic and slide to ensure compatibility. If your slide has been modified, then there may be issues.
• Q: Will the adapter raise my optic's height?
  • A: Yes, in most cases, the adapter will add some height to your optic's mounting. This may affect your ability to co-witness with your iron sights. Consider this factor when choosing an adapter and optic combination. Check how high it will raise the optic, and how this will affect the ability to aim.
• Q: Is thread locker necessary when installing the adapter?
  • A: It is generally recommended to use thread locker on the screws, especially for firearms that experience significant recoil. This helps prevent the screws from loosening over time due to vibration. Blue thread locker is typically preferred, as it allows for easy disassembly if needed. Read the instructions and adhere to these guidelines for the best results.
• Q: How do I remove the adapter if I need to?
  • A: To remove the adapter, simply unscrew the mounting screws using the appropriate wrench. If thread locker was used, you may need to apply some heat to the screws to loosen the adhesive. Be careful not to damage the slide or optic during removal. Follow the same procedures in reverse for the best results.
