Build Your Own: A Guide to the DIY MagnetoSpeed Mount & Chronograph Review

Status: Available (337 KB) Download

As a long-time shooter and outdoor enthusiast, I’ve spent countless hours at the range and in the backcountry, always striving for accuracy and reliable data. One tool that has consistently proven invaluable is the MagnetoSpeed chronograph. However, the standard mounting options can sometimes be limiting. That’s why I’ve become a big advocate for the DIY MagnetoSpeed mount. In this article, I’ll share my experience with the MagnetoSpeed chronograph, explore its benefits, and provide a comprehensive guide to building your own custom mount for enhanced performance and portability. We’ll cover everything from choosing the right materials to ensuring accurate readings, and even a quick MagnetoSpeed chronograph review to help you decide if it’s the right tool for you.

Understanding the MagnetoSpeed Chronograph: A Deep Dive

Before diving into the DIY MagnetoSpeed mount, let’s talk about the chronograph itself. The MagnetoSpeed is a ballistic chronograph that measures the velocity of projectiles without requiring a trip to the shooting range or setting up traditional optical sensors. It utilizes a dual sensor system that detects the projectile twice – once as it passes the first sensor and again as it passes the second. This allows for incredibly accurate velocity readings, even with varying light conditions. (MagnetoSpeed Official Website)

Why Choose a MagnetoSpeed?

  • Portability: Unlike traditional chronographs, the MagnetoSpeed is compact and easy to transport.
  • Accuracy: It consistently delivers reliable and accurate velocity data.
  • Versatility: Compatible with a wide range of firearms, including rifles, pistols, and shotguns.
  • Ease of Use: Simple setup and operation, even for beginners.

I’ve personally used the MagnetoSpeed S2 model for years, and it’s become an essential part of my load development process. I’ve found it particularly useful when testing handloads and verifying factory ammunition performance. The data it provides is crucial for achieving optimal accuracy and consistency.

MagnetoSpeed Chronograph Review: Pros and Cons

Let's be honest, no piece of gear is perfect. Here's my take on the MagnetoSpeed, based on years of use:

Pros Cons
Highly accurate and reliable Can be sensitive to mounting stability
Portable and easy to transport Requires a compatible barrel adapter
Versatile – works with many firearms Price point is higher than some alternatives
Simple to use Battery life can be a concern with frequent use

Overall, the benefits far outweigh the drawbacks, especially if you’re serious about ballistics and accuracy. However, the sensitivity to mounting stability is where the DIY MagnetoSpeed mount comes into play.

The Problem with Standard MagnetoSpeed Mounts

The MagnetoSpeed typically comes with a barrel adapter and a mounting bracket. While functional, these standard mounts can have limitations. They can be bulky, prone to loosening during rapid fire, and may not be ideal for all firearm configurations. I found that the factory mount wasn’t always secure enough for my heavier rifles, leading to inconsistent readings. This is where a custom, DIY MagnetoSpeed mount can make a significant difference.

Designing Your DIY MagnetoSpeed Mount: Considerations

When designing your own mount, several factors should be considered. The goal is to create a stable, secure, and repeatable mounting platform. Here’s what I’ve learned:

  • Firearm Type: The mount should be compatible with your specific firearm and barrel adapter.
  • Stability: Minimize vibration and movement during firing.
  • Repeatability: Ensure the chronograph is positioned consistently for each shot.
  • Portability: Keep the mount lightweight and easy to transport.
  • Material: Choose durable materials that can withstand recoil and environmental conditions.

I’ve experimented with various materials, including aluminum, steel, and even high-strength polymers. Aluminum is a good balance of weight and strength, while steel offers maximum durability. For my primary mount, I opted for 6061 aluminum.

Step-by-Step Guide: Building a DIY MagnetoSpeed Mount

This guide outlines the process for building a simple, yet effective, DIY MagnetoSpeed mount. I’ll focus on an aluminum mount designed to attach to a Picatinny rail, as this is a common mounting system. Disclaimer: Always prioritize safety when working with tools and firearms. If you are not comfortable with metalworking, consider purchasing a pre-made mount.

Materials Needed:

  • Aluminum plate (approximately 4” x 6” x ¼”)
  • Picatinny rail section (length depends on your needs)
  • MagnetoSpeed barrel adapter
  • Screws and nuts (compatible with aluminum)
  • Drill and drill bits
  • Tap and die set (for threading holes)
  • Saw (bandsaw or hacksaw)
  • Files and sandpaper
  • Vise

Instructions:

  1. Cut the Aluminum Plate: Cut the aluminum plate to the desired size and shape.
  2. Drill Mounting Holes: Drill holes in the aluminum plate to match the mounting holes on the Picatinny rail section.
  3. Tap the Holes: Use a tap and die set to thread the holes for the screws.
  4. Attach the Picatinny Rail: Securely attach the Picatinny rail section to the aluminum plate using screws and nuts.
  5. Drill Holes for the MagnetoSpeed Adapter: Carefully position the MagnetoSpeed barrel adapter on the aluminum plate and mark the mounting holes. Drill and tap these holes.
  6. Attach the MagnetoSpeed Adapter: Securely attach the MagnetoSpeed barrel adapter to the aluminum plate.
  7. Deburr and Finish: Use files and sandpaper to remove any sharp edges or burrs. You can also apply a protective finish to prevent corrosion.

I’ve found that adding a rubber pad between the chronograph and the mount helps to dampen vibrations and improve accuracy. I sourced a small piece of neoprene from a local hardware store.

Testing and Calibration: Ensuring Accuracy

Once your DIY MagnetoSpeed mount is complete, it’s crucial to test and calibrate it. Here’s how I do it:

  1. Secure Mounting: Ensure the mount is securely attached to your firearm.
  2. Leveling: Verify that the chronograph is level.
  3. Multiple Shots: Fire a series of shots with the same ammunition and record the velocity readings.
  4. Compare to Known Data: Compare the readings to known velocity data for the ammunition.
  5. Adjust as Needed: If the readings are inconsistent, check the mounting stability and make any necessary adjustments.

The National Shooting Sports Foundation (NSSF) offers excellent resources on firearm safety and accuracy. Always follow safe shooting practices.

Beyond the Basics: Advanced DIY MagnetoSpeed Mount Options

For those looking for more advanced options, consider these ideas:

  • Adjustable Mount: Design a mount with adjustable height and angle for greater versatility.
  • Quick-Detach Mount: Incorporate a quick-detach mechanism for easy installation and removal.
  • Integrated Bubble Level: Add a bubble level to the mount for precise leveling.
  • 3D Printed Mounts: Explore 3D printing for creating custom mounts with complex geometries.

Leave No Trace: Responsible Shooting Practices

When shooting outdoors, it’s essential to practice Leave No Trace principles (Leave No Trace Center for Outdoor Ethics). This includes packing out all trash, respecting wildlife, and minimizing your impact on the environment. The USDA Forest Service (USDA Forest Service) provides guidelines for responsible shooting on public lands. Always be aware of your surroundings and follow all applicable regulations.

Final Thoughts on the DIY MagnetoSpeed Mount

Creating a DIY MagnetoSpeed mount is a rewarding project that can significantly improve the accuracy and portability of your chronograph. While the MagnetoSpeed is a fantastic tool on its own, a well-designed mount can unlock its full potential. I hope this guide has provided you with the knowledge and inspiration to build your own custom mount and take your shooting to the next level. Remember to prioritize safety, accuracy, and responsible outdoor practices. Happy shooting!
