Mounting a rifle scope correctly isn't just about slapping it on and tightening screws. Whether you're a seasoned hunter, competitive shooter, or weekend range-goer, how you mount your scope affects your accuracy, consistency, and confidence. At MCJ Optics, we believe that a properly mounted scope is the foundation of precision shooting.
Why Proper Scope Mounting Matters
Improper mounting leads to poor eye relief, misaligned reticles, and inconsistent point-of-impact shifts. This can ruin an otherwise reliable optic. Mounting your rifle scope the right way ensures:
- Optimal eye relief and shooting comfort
- Consistent reticle leveling
- Secure, torque-balanced installation
- Maximum repeatability and zero retention
Step-by-Step Guide to Mounting Your Rifle Scope
1. Gather the Right Tools
- Torque wrench or driver
- Bore sighter (optional but recommended)
- Bubble level or leveling kit
- Properly sized rings and base mount (Picatinny, Weaver, etc.)
- Thread-locking compound (non-permanent)
2. Secure the Rifle
Place the rifle in a gun vise or a stable rest to ensure a level and stationary platform. This prevents any movement during the installation process.
3. Install the Base Mount
Attach the base to the rifle’s receiver using manufacturer-recommended torque settings (usually 15–20 in-lbs). Use a thread-locker to prevent screws from loosening over time.
4. Position the Scope Rings
Align your rings evenly on the base and loosely tighten them. Ensure they're spaced to support the scope body without interfering with turrets or adjustment dials.
5. Set Eye Relief
Slide the scope into the rings and position it for optimal eye relief. A good rule of thumb is to mount the scope so the image is full and crisp when you shoulder the rifle naturally.
6. Level the Reticle
Place a bubble level on the elevation turret and another on the rifle’s rail or bolt face. Rotate the scope until both are level. A canted reticle leads to shot placement errors at distance.
7. Torque the Ring Screws
Evenly tighten the top screws in a crisscross pattern using 15–18 in-lbs torque. Over-tightening can damage the scope tube. Under-tightening risks movement under recoil.
8. Confirm Alignment and Zero
Use a bore sighter to get on paper at 25–50 yards. Then live-fire zero your scope at your preferred distance. Check and adjust reticle level if needed.
Pro Tips from the Experts
- Always use a torque wrench: Guessing leads to stripped screws or inconsistent pressure.
- Don't skip leveling: A canted scope throws off windage and elevation adjustments.
- Use quality mounts: Cheap mounts often fail under recoil or cause scope shift over time.
- Protect your investment: MCJ Optics scopes are backed by a lifetime warranty — but even the best scope can underperform if mounted poorly.
