Optics Mounting DIY Guide: A framework of zeroing optics
Introduction
Optics significantly improve a firearm’s accuracy for hunting, competitive shooting, or just for fun at the range. Proper installation and zeroing of your scope or red dot sight are critical for optimal performance. This guide will provide you a framework to follow regardless of your firearm being a long gun or a handgun using the tools that I use on my bench.
Tools and Materials
- Real Avid Master Grade Scope Mounting and Bore Sighting Kit
- Real Avid Master Gun Workstation (for rifles)
- LaserLyte laser bore sight (for pistols)
- Selected scope or red dot sight
- Firearm (rifle or pistol)
- Ammunition (for live fire zeroing)
- Screwdrivers (as required by your optic’s mount)
- Torque wrench (included in the Real Avid Master Grade Scope Mounting and Bore Sighting Kit)
Recommended Torque Specifications for Mounting Optics
| Component | Torque Specification (inch-pounds) | Notes |
|---|---|---|
| Scope Base Screws | 25-30 | Check firearm manufacturer’s spec if mounting to aluminum receivers |
| Ring Cap Screws | 15-20 | Common range for most rifle scopes |
| Picatinny Rail Screws | 30-35 | Can vary based on rail and firearm material |
| Side Mount Screws | 35-45 | For larger tactical mounts, check specific mount requirements |
| Cantilever Mounts | 20-25 | Common for red dot sights |
Note: Always confirm with the scope and mount manufacturer’s instructions before applying these settings, as incorrect torque can damage your equipment. Additionally, ensure that all threads are clean and that you are using a calibrated torque wrench. It’s advisable not to use thread locking compounds unless specifically recommended by the manufacturer, as this can affect torque values.
Step 1: Secure Your Firearm
Ensure the firearm is unloaded. Secure it within the Real Avid Master Gun Workstation, which provides a stable platform necessary for precision work.
Step 2: Attaching the Optic
For Rifles: Attach the scope mount base to the rifle using the Real Avid Smart-Torq, ensuring it is tightened to the manufacturer’s recommended torque, usually between 25-35 inch-pounds for most bases.
For Pistols: Attach your red dot sight to the pistol’s slide, ensuring all screws are tightened according to manufacturer’s specifications to prevent any movement during firing.
Step 3: Aligning and Leveling the Scope
For Rifles: Install the scope within the rings, adjusting for proper eye relief and ensuring the scope is perfectly horizontal using the Reticle level provided in your kit. Lightly tighten the scope ring screws so the scope can still be adjusted but is secure enough to stay in place.
Step 4: Precision Torquing of Scope Rings
Use a torque wrench to apply the correct torque to the scope ring screws. Vortex recommends 15-18 inch-pounds for their rings, which is a common setting for many manufacturers. Ensure to incrementally tighten the screws in a crisscross pattern to evenly distribute pressure and avoid damaging the scope tube.
Step 5: Bore Sighting
For Rifles: Use the bore sighting tool to align the crosshairs with a predetermined point at a set distance. Adjust the scope’s elevation and windage until the crosshairs center on the point indicated by the bore sighter.
For Pistols: Insert the LaserLyte laser bore sight into the barrel. Adjust the red dot sight so its point of aim matches the laser’s point on a target.
Step 6: Live Fire Zeroing
Conduct live firing at a range to fine-tune the zero:
- For Rifles: Start at a short distance to verify the bore sight zero, shooting a three-round group and adjusting as necessary. Gradually increase the distance and repeat the process.
- For Pistols: Ensure the red dot consistently aligns with the point of impact and adjust as needed.
Conclusion
Proper installation and zeroing of optics are crucial for achieving optimal performance from your firearm. Using precise tools like those from Real Avid ensures that your optics are not only mounted securely but are also accurately aligned. Patience during setup leads to better performance downrange, ensuring reliability whether you’re competing, hunting, or practicing.
By adhering to the specific torque settings recommended by scope manufacturers and following a methodical installation process, shooters can ensure their scope maintains accuracy and stability over time.
