Mounting a scope can be tricky, and sometimes, even experienced shooters accidentally install a cantilever scope mount backwards. This seemingly simple mistake can have serious consequences, impacting accuracy, zeroing, and even the structural integrity of your rifle and mount. This guide will explore the reasons why you shouldn't mount a cantilever scope mount backwards, the potential problems it causes, and how to correctly install it.
Why You Should Never Mount a Cantilever Scope Mount Backwards
The design of a cantilever scope mount is crucial for proper functionality. It's engineered to extend the scope forward, providing a greater distance from the receiver, which is beneficial for eye relief and clearance, especially with larger optics. Mounting it backwards directly negates this design, leading to a series of issues.
1. Compromised Eye Relief: A Major Safety Hazard
Incorrect mounting drastically reduces or eliminates eye relief. This means your eye might be too close to the scope’s eyepiece, potentially leading to injury from the recoil. In the worst-case scenario, the scope could even recoil back and hit your eye. Safety should always be your top priority.
2. Impaired Zeroing and Accuracy
A backwards cantilever mount throws off the scope's alignment with the barrel. This makes zeroing incredibly difficult, if not impossible, rendering your rifle inaccurate. You'll experience significant point-of-impact shifts, making it almost useless for any precise shooting.
3. Weakened Mount Structure and Potential Damage
Cantilever mounts are designed to withstand recoil forces when installed correctly. Mounting it backwards might put undue stress on the mounting points, potentially leading to damage to the mount itself or even to the receiver of your rifle. This can result in a costly repair or even render your firearm unsafe.
4. Obstructed Access to Rifle Controls
Depending on the rifle and scope combination, a backwards-mounted cantilever might obstruct access to vital controls, such as the bolt handle or safety selector. This significantly impacts your ability to operate the rifle smoothly and efficiently.
Identifying a Backwards Mount: Quick Checks
Before you even attempt to sight in your rifle, visually inspect the mount. Here are some key indicators:
- Clamping Mechanism: Observe the position of the clamping mechanism. It should firmly grasp the scope's rings, and the clamping pressure should be appropriately distributed. A backwards mount often shows uneven clamping or an unnatural position of the levers.
- Scope Alignment: Check the scope's alignment with the barrel. A correctly installed scope should be parallel to the barrel. If it's noticeably offset, it is likely installed incorrectly.
- Eye Relief: Attempt to look through the scope. If you cannot achieve comfortable eye relief without extreme forward or backward movement of your head, the mount is almost certainly backwards.
Correcting the Mistake: Proper Installation
If you've identified a backwards mount, immediately rectify the situation. Follow the manufacturer's instructions precisely for proper installation. If you are unsure about any aspect of the process, seek assistance from a qualified gunsmith. This is not a DIY project that should be rushed. Take your time and ensure everything is secure and correctly aligned.
Prevention: A Few Tips
- Read the Instructions: Always thoroughly read the instructions provided with your cantilever scope mount before beginning installation.
- Double-Check Everything: Take your time, and double-check the alignment and clamping before tightening everything down.
- Seek Professional Help: If you're uncertain about any step, seek assistance from a professional gunsmith who can ensure correct installation.
By understanding the potential dangers and following these guidelines, you can avoid the pitfalls of mounting a cantilever scope mount backwards and enjoy safe, accurate shooting. Remember, safety and accuracy are paramount. Never compromise on either.
