Understanding Cantilever Scope Mounts and Their Purpose
A Deeper Dive
In the realm of precision shooting and firearm customization, the choices available can feel nearly limitless. From the type of rifle to the ammunition used, every element contributes to accuracy and performance. One critical component often overlooked is the scope mount, the often-unsung hero that securely holds your optic, allowing you to accurately place shots downrange. While standard scope mounting practices are well-understood, a lesser-explored approach involves mounting a **cantilever scope mount backwards**. This seemingly counterintuitive method, while not a mainstream practice, can offer distinct advantages in specific scenarios. This article will delve into the circumstances where this unconventional technique becomes a viable option, examining its benefits, drawbacks, and practical considerations.
Understanding the typical function of a scope mount is fundamental. A **cantilever scope mount**, in its standard configuration, is designed to extend the scope forward, often providing the user with ample eye relief. This forward extension is usually coupled with a design that allows the scope to sit above the handguard. This design feature becomes essential for firearms like AR-15 style rifles where the handguard is often positioned directly below the scope. The main purpose of a cantilever mount is usually to place the scope at the optimal distance from the shooter’s eye while simultaneously providing room on the receiver or top rail for other accessories, like backup iron sights. The benefits of the standard setup are clear: clear sight pictures, comfortable shooting positions, and the ability to quickly acquire targets. The design generally provides enough length to find the sweet spot of eye relief for many popular scopes.
Situations Where Mounting Backwards Might Be Considered
Unique Rifle Configurations
Now, let’s shift gears and consider the less-traveled path: using a **cantilever scope mount backwards**. The motivation to do this stems from a variety of factors, typically related to overcoming limitations posed by specific firearms configurations or achieving a better balance of ergonomics. Understanding these situations is key to appreciating the utility of this approach.
One significant driver for mounting a **cantilever scope mount backwards** centers around unique rifle designs. Take, for instance, rifles with short barrels or bullpup designs. These firearms, which position the action behind the trigger and within the stock, present unique challenges to scope mounting. The space available for mounting is often extremely limited. Traditional scope mounting can be a struggle as you are trying to fit a scope in a very compact area. Mounting a scope backwards, while unusual, might provide the needed space to clear certain parts of the rifle or allow for better access to controls. The forward extension of the mount, typically designed for eye relief on standard rifles, can instead be used to clear the charging handle on some bullpup configurations. The user is trading some of the functionality of the cantilever extension and gaining other benefits such as scope clearance.
Eye Relief Considerations
Beyond unusual rifle configurations, eye relief presents another area where mounting a scope mount backwards might become an important consideration. Eye relief, the distance between your eye and the scope’s ocular lens where a full sight picture is visible, is critical for accurate shooting and comfortable use. Some scopes have inherent eye relief challenges, meaning they may need a long eye relief. Mounting a cantilever scope mount backwards could allow the user to position the scope further back on the rail than it would be able to normally. This backwards configuration could grant the shooter the needed eye relief. Conversely, shorter eye relief scopes might also benefit from this setup, which could permit the shooter to position the scope closer to themselves. The specific needs of the individual shooter and the characteristics of the scope are paramount.
Accessory Placement
Another significant advantage in mounting a cantilever scope mount backwards revolves around accessory placement. Modern firearms often have multiple accessories, ranging from backup iron sights to laser pointers. When accessories such as night vision devices are in use, or when a scope is being used with backup iron sights, the amount of available rail space can become a valuable commodity. Mounting the cantilever backwards might then free up space, allowing the user to mount their accessories without sacrificing sight picture or causing interference. This, in turn, allows for a more versatile and adaptable platform.
Advantages of Mounting a Cantilever Scope Mount Backwards
While mounting a **cantilever scope mount backwards** offers potential advantages, it’s essential to weigh these against the accompanying disadvantages. One of the first problems one may encounter is the limited amount of rail space. Even with the mount reversed, the length of the rifle’s rail may limit the mounting options available. The reversed mount might not be sufficient to accommodate the chosen scope or other accessories, thereby negating the initial advantages. This often means that the user has to choose which accessories are more important.
Another significant consideration is the impact on the rifle’s balance. The cantilever design is normally used to offset the weight of the scope. Reversing the mount can dramatically alter the balance of the rifle. The weight distribution is changed, often shifting more weight towards the rear. This can lead to different handling characteristics, potentially making the rifle feel less balanced or less responsive during rapid target acquisition. This has to be considered by shooters, especially if their firearm is a hunting rifle or a competition platform.
Aesthetics also come into play, though they are subjective. Some shooters may find the reversed setup less visually appealing. While this is purely a matter of personal preference, it’s worth considering if you value the overall look and feel of your rifle.
Furthermore, scope size limitations are a factor. Not all scopes will work effectively with a backwards cantilever mount. Larger scopes, or scopes with bulky turrets, may interfere with the operation of the charging handle or other components, rendering the rifle unfunctional.
The method of zeroing may be different. With a mount installed backwards, you may need to adjust your approach to zeroing the scope. It is vital that the mount is secured correctly, or else your zero will be unstable.
Installation and Practical Tips
So, how does one actually go about the implementation of mounting a **cantilever scope mount backwards**? If your mount allows for such an installation, which is not a guarantee, the process can often be straightforward. The first step is to ensure your mount is designed for this setup. Not all mounts can be mounted in reverse. When fitting it, carefully align the mount on your rail, ensuring it’s properly seated and secured. Tighten the screws with the appropriate torque specifications, as per the manufacturer’s recommendations. This is a crucial step for ensuring your scope remains firmly in place under recoil. After installation, you’ll need to zero your scope. This will be done the same way as with a standard forward installation, but you may need to make more adjustments. Take your time, and make small adjustments to compensate for the reversed positioning. Remember to always check your scope’s mounting hardware before each shooting session.
Real-World Examples and Case Studies
While this technique is not a common practice, there are some real-world examples. Enthusiasts on online forums and communities have discussed using this approach on various rifles, including AR-15s and other tactical platforms. Many shooters have discovered its advantages when facing space limitations. While experiences vary, those who have embraced the technique often highlight improved eye relief or more room for accessories as the primary benefits. Sharing experiences and seeing the results from others is one of the most valuable ways of learning.
Conclusion
In conclusion, mounting a **cantilever scope mount backwards** is a specialized technique with the potential to offer real advantages in specific contexts. While it’s not a standard practice, it can prove valuable in unique situations, such as on short barrel rifles or those with unusual configurations, eye relief needs, or complex accessory setups. While not a one-size-fits-all solution, it is a useful consideration for shooters wanting to fine-tune their platforms. Consider the balance between advantages and disadvantages, assess your specific needs, and the characteristics of your scope, before proceeding with this approach. Always ensure correct installation and always adhere to best safety practices. If in doubt, consult with a qualified gunsmith or experienced shooter for advice.
