Understanding Glue-On Sights
Types of Glue-On Sights
The world of shotguns, from the venerable hunting companion to the steadfast home defense tool, is a world of customization and adaptation. One crucial element in maximizing the performance of any shotgun is its sights. These small yet essential components are the key to precise target acquisition, whether you’re aiming for a fleeting dove or confronting a potential threat. While there are a multitude of sighting options available, from sophisticated optics to iron sights, this article delves into a practical, cost-effective, and accessible solution: glue sights on shotgun barrels. This guide is designed for the beginner, providing a comprehensive understanding of these sights, how to install them, and the considerations involved in their use.
Advantages of Glue-On Sights
Before delving into the practical aspects of installation, it’s critical to establish a solid foundation of knowledge about glue sights. The term “glue-on” itself might sound simplistic, implying the use of common adhesives. However, the reality is more nuanced. While the concept relies on bonding, the choice of adhesive is paramount, and the term encompasses a range of options designed specifically for this purpose.
One of the most significant aspects of glue-on sights is their diversity. The market offers a variety of types catering to different needs and preferences. Bead sights, the most basic and arguably the most traditional, are a common choice. They are typically small, round, and intended for quick target acquisition at close range. Their simplicity translates to ease of installation. Fiber optic sights are another popular option. These sights utilize a fiber optic rod, which collects ambient light and channels it, creating a bright, easily visible aiming point. Fiber optic sights are particularly beneficial in low-light conditions, enhancing target visibility. You can also find hybrid models.
The materials used in glue-on sights are diverse, with plastic and metal as the predominant components. Plastic sights often offer cost-effectiveness, while metal sights provide greater durability. Fiber optic sights are typically comprised of a durable plastic or metal housing with a fiber optic rod. The choice of material often depends on the intended use of the shotgun.
Disadvantages to Consider
The primary advantage of glue-on sights is their cost-effectiveness. Compared to professionally installed sights, such as those that require drilling and tapping, glue-on options are significantly cheaper. This makes them an excellent choice for budget-conscious shooters, or those who are just starting out in shotgun sports.
Beyond the financial benefits, glue-on sights shine in their ease of installation. The process typically requires minimal tools, often just a degreaser, an adhesive, and perhaps a small applicator. This contrasts sharply with the expertise required for more permanent installations, which may necessitate specialized tools and gunsmithing knowledge.
Flexibility is another key benefit. Glue-on sights are often non-permanent or easily reversible. This is particularly useful for those who like to experiment with different sight types or find the best setup for their needs. The ability to easily remove or replace a sight is a huge advantage.
Finally, glue-on sights provide a versatile solution for a wide range of shotguns. Regardless of the make or model, as long as the barrel’s profile allows for mounting, these sights can be a viable option. This broad applicability makes them a valuable accessory for many shotgun owners.
Choosing the Right Sight
Compatibility is Key
While glue-on sights present a compelling option, it’s essential to recognize their potential limitations. The most prominent concern revolves around durability. The bond of the adhesive can be compromised by extreme temperatures or by repeated impacts, especially if the firearm is subject to rough handling. For shotguns used in harsh environments or those used in the most demanding applications, more robust sights may be preferable.
Compared to sights mechanically attached, glue-on options are inherently less durable. While modern adhesives are strong, they will never match the strength of a sight that is securely fastened with screws. This difference is less critical for casual shooters but could be a concern for those engaging in competition shooting or heavy-duty use.
Ultimately, the choice of a glue-on sight should be carefully considered in light of the intended use. They are excellent for recreational shooting, hunting at moderate distances, and home defense. But, if you are anticipating the harsh conditions, consider a more robust option.
Material and Design Considerations
Selecting the right glue-on sight is a critical step towards a successful outcome. There are various factors to take into account, and considering these variables can determine the sight’s functionality and longevity.
The first step is ensuring compatibility with your shotgun. Focus on sights specifically designed for shotguns. Consider the barrel diameter. While some sights are “universal,” others are designed to fit a specific barrel profile.
The barrel rib width is another important consideration. The rib is the raised area along the top of the barrel, to which sights are often attached. Measure the width of your rib and ensure that the sight you choose is compatible. If you’re using a vent rib, make sure the sight is designed for that configuration.
Choosing the Right Adhesive
Material and design play a significant role in the effectiveness of a glue-on sight. Choose materials that are resistant to the elements. Metal sights can be more durable, but plastic sights may be lighter and less prone to scratching your barrel.
The design of the sight itself is also critical. Consider the height and profile of the sight. Too low, and it may not provide an adequate sight picture. Too high, and it might interfere with the operation of the shotgun. Choose sights that complement your shooting style and your intended use.
Installation: A Step-by-Step Guide
Preparing the Barrel
Perhaps the most critical element in the process is selecting the correct adhesive. While the term “glue” is used colloquially, it’s important to use an adhesive specifically designed for the purpose, not something from your craft supplies.
There are several choices for glues, each with pros and cons. Cyanoacrylate adhesives, often known as super glues, are known for their fast setting times and exceptional bond strength. They provide strong bonding and are readily available. However, some formulations are less resistant to heat and impact than others. Epoxy adhesives offer excellent strength and durability, especially when exposed to higher temperatures. They are generally very robust.
UV-cured adhesives are an increasingly popular option, as they cure rapidly when exposed to ultraviolet light. This process results in a very strong bond, but it is reliant on a UV light source and the surface being transparent enough for the light to penetrate.
Whatever adhesive is used, it must be heat-resistant, especially if you expect to fire multiple rounds quickly. The barrel can get hot after repeated shots.
Mounting the Sight
Installing glue-on sights can seem intimidating at first, but with proper preparation and following the appropriate steps, it’s a manageable task.
The initial and arguably most crucial step is the preparation of the barrel’s surface. Begin by cleaning the area where the sight will be mounted. Use a high-quality degreaser to remove any oil, grease, or other contaminants that could interfere with adhesion. Remove all traces of residue from the cleaning agent.
If the barrel has any significant blemishes or imperfections in the mounting area, you might consider lightly sanding the surface with fine-grit sandpaper. This will create a slightly rougher surface, increasing the bonding surface area for the adhesive.
Post-Installation Checks
Before you begin, ensure you have all the necessary tools and materials: the sight, the adhesive, a degreaser, sandpaper (if needed), applicators for the adhesive, masking tape.
Carefully apply the adhesive according to the manufacturer’s instructions. Most products recommend a thin, even layer. Apply a small amount of adhesive to the base of the sight or the barrel surface. Apply a little more to the sight, and then a little more to the barrel. Make sure your gloves or bare hands are clean before the next step.
Precisely position the sight on the barrel. Refer to the existing bead sight or any markings present on the barrel to align it correctly. Using a level is also advisable. Align the sight carefully and hold it firmly in place.
Use masking tape to secure the sight while the adhesive cures. Apply the tape along the base of the sight and the barrel, ensuring that the sight remains properly aligned and in contact with the surface. Take your time, be patient, and double-check your alignment before the adhesive sets.
Carefully follow the adhesive’s curing time instructions. Curing times vary widely depending on the adhesive type. This is a critical step to ensure the sight is properly attached. Let the sight remain undisturbed throughout the curing process.
Considerations for Use and Maintenance
Alignment and Zeroing
After the adhesive has fully cured, carefully remove the masking tape. Visually inspect the sight to ensure it is securely attached and properly aligned.
Take the shotgun to a safe and clear space. If your sight allows, try a dry fire. This helps assess the sight picture and make sure it aligns with your natural point of aim.
Finally, test fire your shotgun. The test firing will confirm the sight’s functionality. If necessary, adjust the point of impact.
Durability and Longevity
The initial installation is merely the first step; proper zeroing is essential for optimal performance. Zeroing refers to adjusting the sight to align the point of impact of your shots with your point of aim. This will differ based on the specific use you require.
To zero the sight, you will need a suitable target and ammunition. Start by firing a few shots at a distance, such as 25 yards. Observe the point of impact and adjust the sight as needed to bring the shots to the desired point of aim. Remember to make small adjustments.
Legal Considerations
Glue-on sights are generally durable, but there are a few elements that can impact the sight’s lifespan. Heat is a major factor. Rapid firing can elevate the barrel’s temperature. Impact is another. If the shotgun is dropped or subjected to significant force, the sight bond can be compromised.
Regularly inspect the sight for any signs of loosening or damage. Keep the sight clean to ensure optimal visibility.
Troubleshooting Common Issues
Solutions and Best Practices
Ensure that the installation of glue-on sights complies with all applicable laws and regulations. State and local laws may place restrictions on the types of sights that can be used on firearms, particularly in certain hunting or competition scenarios.
Even with careful installation, a few problems may arise. Understanding these issues and their solutions will help maintain a functional sight.
A common issue is the sight coming loose. If this happens, first try to remove the sight (this may be difficult) and clean the surface. If possible, apply a fresh adhesive.
If you have trouble with alignment, recheck the installation process. Verify that the sight is properly aligned and that the sight picture is clear. Double check how the bead aligns with the back sights.
If you find it challenging to see the sight picture, try different lighting conditions. If the issue persists, consider using a fiber optic sight that offers improved visibility in low-light conditions.
Conclusion
