The satisfying thwack of a well-maintained air rifle is often overshadowed by the jarring noise. This is where the humble oil can silencer adaptor comes in. While not a true suppressor in the legal sense, it significantly reduces the report of your airgun, making it more pleasant to shoot and neighbor-friendly. This guide explores everything you need to know about oil can silencers and their adaptors.
Understanding the Oil Can Silencer Adaptor
An oil can silencer adaptor is precisely what its name suggests: an adaptor designed to fit onto the end of your air rifle's barrel, allowing you to attach an empty oil can (or other suitable container) to act as a makeshift silencer. It's crucial to understand that these are not professional-grade silencers and their effectiveness varies considerably depending on the design of the adaptor, the oil can itself, and the airgun being used.
How it Works
The adaptor creates a connection between your airgun and the oil can. The air exiting the barrel passes through the oil can, causing expansion and reducing the velocity of the expelled air. This expansion process dissipates some of the energy, resulting in a quieter shot. The internal baffles and chambers within the oil can further contribute to sound dampening, although this is often less controlled than in purpose-built suppressors.
Choosing the Right Oil Can Silencer Adaptor
The market offers several variations in design and materials. When choosing an adaptor, consider these crucial factors:
1. Material:
- Steel: Offers superior durability and longevity. Steel adaptors are generally more robust and can withstand higher pressures.
- Aluminum: Lighter than steel but potentially less durable, especially with high-powered air rifles.
- Plastic: Often cheaper but the least durable option. Not recommended for high-powered airguns.
2. Threading:
The adaptor must have the correct threading to match your air rifle's barrel. Incorrect threading will lead to an insecure and potentially dangerous connection. Always verify the threading specifications of both your air rifle and the intended adaptor before purchase. Common thread types include 1/2" UNF, 1/2" BSF, and others specific to certain airgun manufacturers.
3. Design:
Some adaptors incorporate additional features designed to improve silencing, such as internal baffles or chambers. These additions may provide a more noticeable reduction in noise.
Safety Precautions:
Using an oil can silencer adaptor is inherently less safe than using a purpose-built silencer. Always prioritize safety:
- Properly Secure the Adaptor: Ensure the adaptor is securely tightened onto the barrel to prevent it from detaching during firing.
- Oil Can Condition: Use only empty and clean oil cans. Avoid using cans that have contained flammable or explosive substances.
- Eye and Ear Protection: Always wear appropriate eye and ear protection when using any type of silencer.
- Legal Compliance: Check your local laws and regulations regarding the use of homemade silencers or modifications to firearms.
Alternatives to Oil Can Silencer Adaptors
While oil can adaptors offer a budget-friendly solution, purpose-built airgun suppressors provide superior noise reduction, safety, and durability. Investing in a quality suppressor is a worthwhile consideration for serious airgunners.
Conclusion
Oil can silencer adaptors offer a DIY approach to reducing the noise of your air rifle. However, users must proceed with caution, ensuring safety is prioritized. Understanding the limitations of this method and carefully selecting an adaptor are crucial to a safe and enjoyable shooting experience.
