How To Avoid The Most Common Mistakes While Mounting A Scope

How To Avoid The Most Common Mistakes While Mounting A Scope

Mounting a rifle scope might seem straightforward, but even seasoned shooters can fall into traps that compromise accuracy, waste time at the range, and burn through expensive ammunition. Jon LaCort of TRACT Optics breaks down the most frequent mistakes and how to avoid them—so your scope performs exactly as it should.

Why Scope Mounting Mistakes Matter

Improper mounting leads to a host of frustrating issues:

• Scope won’t hold zero
• Tracking inconsistencies
• Internal damage to the erector assembly
• Stripped screws and uneven pressure
• Wasted ammo chasing phantom problems

Avoiding these pitfalls means more time shooting tight groups and less time troubleshooting.

Common Mistake #1: Over-Tightening the Rings

One of the most common errors is cranking down the ring screws too hard. It’s tempting to think tighter is better—but overtightening compresses the scope tube and interferes with the internal erector system, causing tracking issues and loss of zero.

Best Practice:

• Use a torque wrench.
• Do not exceed 18 inch-pounds on ring screws.
• Evenly tighten screws in a cross-pattern to distribute pressure.

Common Mistake #2: Mismanaging Base Screws

Base screws are a different story. They require more torque and a touch of thread locker—but only in the right places.

Best Practice:

• Torque base screws to 25 inch-pounds.
• Apply blue Loctite only to base screws—not to ring screws or ring-to-base screws.
• For ring-to-base screws, consult the ring manufacturer. TRACT recommends 25 inch-pounds for MDT rings.

Whether you’re mounting a TORIC 30mm LR or the TORIC 34mm ELR series, these rings deliver the secure fit and sleek finish that serious shooters demand.

Avoid The Most Common Scope Mounting Mistakes

Common Mistake #3: Not Positioning Rings Correctly

Recoil naturally pushes the scope forward. If your rings aren’t seated properly, the scope can shift over time.

Best Practice:

• Push rings toward the muzzle before tightening.
• Ensure rings are fully seated in the Picatinny or Weaver slots.
• Use rings like MDT’s double-screw design for added stability.

Common Mistake #4: Uneven Screw Tightening

Uneven torque across screws can warp the scope tube and cause internal misalignment. This is especially problematic with traditional ring tops.

Best Practice:

• Tighten screws incrementally and evenly.
• Use rings that allow balanced tightening (MDT rings are a great example).
• Avoid gaps on one side of the ring top—aim for symmetry.

Common Mistake #5: Using the Wrong Tools

The wrong bit can strip screws and ruin your mounting hardware.

Best Practice:

• Use hollow-ground bits that fit snugly.
• Invest in a quality toolkit like the Real Avid set.
• Avoid bits that wiggle or don’t seat fully in the screw head.

Recommended Tools

Jon recommends the Capri Tools torque wrench, which covers a wide range from under 10 inch-pounds up to 50—perfect for scope mounting, action screws, and more.

Final Thoughts

Mounting your scope correctly isn’t just about following steps—it’s about precision, patience, and the right tools. By avoiding these common mistakes, you’ll:

• Protect your optic investment
• Save time at the range
• Preserve your ammo
• Ensure your rifle performs at its peak

Whether you’re a first-time scope installer or a seasoned hunter, these tips will help you get it right the first time.
