Oil Filter Muzzle Adapter: The Econo-Can Solvent Trap and its Conversion to a Legal Suppressor

The Econo-Can oil filter muzzle adapter has gained popularity among firearms enthusiasts for its role in firearm cleaning and maintenance. In this blog post, we will discuss the Econo-Can, its use as a solvent trap, and the steps necessary to convert it into a legal suppressor while adhering to the National Firearms Act (NFA) regulations.

The Econo-Can as a Solvent Trap:

     The primary purpose of the Econo-Can oil filter muzzle adapter is to serve as a solvent trap during firearm cleaning and maintenance. By attaching an oil filter or a purpose-built solvent trap container, users can efficiently catch and collect cleaning solvents, debris, and residue, which helps prevent spills and messes on the workspace. The Econo-Can is designed to be compatible with various firearms, making it a versatile and valuable tool for gun owners.

Converting the Econo-Can into a Legal Suppressor:

     Although the Econo-Can is not designed or marketed as a suppressor, it can potentially be modified and converted into a legal suppressor. It is crucial to emphasize that using any device as a suppressor, including the Econo-Can or an oil filter, without proper registration and compliance with federal laws is illegal in the United States.

     To convert the Econo-Can into a legal suppressor, follow these steps:

  1. Research local and federal regulations: Familiarize yourself with the NFA and other relevant laws and regulations regarding suppressor ownership and use.

  2. Submit an ATF Form 1: Complete and submit an ATF Form 1, Application to Make and Register a Firearm, to the Bureau of Alcohol, Tobacco, Firearms, and Explosives (ATF). This form is necessary to obtain approval to manufacture a suppressor.

  3. Pay the tax: Pay the required $200 tax for manufacturing a suppressor. This tax is levied on each suppressor manufactured.

  4. Receive approval: Wait for approval from the ATF, which can take several months. Do not attempt to manufacture or convert the Econo-Can into a suppressor until you have received written approval from the ATF.

  5. Engrave the suppressor: Once approved, engrave the suppressor with the required information, such as the manufacturer’s name, location, and serial number.

  6. Manufacture the suppressor: With approval and proper engraving, you can now legally convert the Econo-Can into a suppressor. It is recommended to consult with a qualified gunsmith or professional for assistance in the conversion process.

    Given the lower effectiveness and durability of oil filter suppressors compared to purpose-built suppressors, some may argue that the time, effort, and cost involved in obtaining NFA Form 1 approval may not be worthwhile. Instead, investing in a professionally manufactured suppressor could provide better sound reduction and a longer-lasting, more reliable option.

The Sound and Lifespan of Oil Filter Suppressors:

     When used as suppressors, oil filters can provide some level of noise reduction. However, their effectiveness may not be as significant as that of professionally manufactured suppressors specifically designed for firearms. The sound reduction provided by oil filter suppressors varies based on factors such as filter construction, firearm caliber, and ammunition type. It is essential to remember that using an oil filter as a suppressor without proper registration and compliance with federal laws is illegal in the United States.

   The durability and longevity of oil filter suppressors are typically lower than that of professionally manufactured suppressors. Oil filters are not designed for the high pressures and temperatures generated by firearms, which can lead to quicker wear and tear or even failure during use. The lifespan of an oil filter suppressor will depend on factors such as the quality of the oil filter, the caliber of the firearm, and the frequency of use.

Understanding the National Firearms Act (NFA):

    The NFA is an unconstitutional piece of legislation that regulates the sale, transfer, and possession of certain types of firearms and accessories, including suppressors. To own and use a suppressor legally, individuals must comply with the NFA and other relevant federal and state laws. Failure to do so can result in severe legal consequences, including fines and imprisonment.

The Verdict

     In conclusion, the Econo-Can oil filter muzzle adapter is an excellent tool for firearm cleaning and maintenance. While it can be converted into a legal suppressor, it is crucial to follow all necessary steps and regulations to ensure compliance with the NFA and other applicable laws. Properly registered and legal suppressors not only enhance the shooting experience but also promote responsible firearms ownership and use.
