Guns.com makes it simple to buy a suppressor online. We provide you with any information you may need to know.
To know if a suppressor is compatible with your gun, follow these steps:
Compatibility
Caliber Matching:
Ensure the suppressor is rated for your gun's caliber. Many suppressors are multi-caliber, meaning they can handle different rounds, but always check the specifications.
Select your caliber to view compatible product options:

Threading:
Confirm the suppressor's threading matches your gun’s barrel threading. Most suppressors attach directly to the barrel using specific thread patterns, so they must match. Silencer Central offers a barrel threading service if your gun barrel is not threaded.

Barrel Length
Check that the suppressor is suitable for your gun's barrel length. Some suppressors work best with longer barrels, while others are designed for shorter setups.
Pressure Rating:
Ensure the suppressor can handle the pressure generated by the type of round your gun fires, especially if you’re using high-pressure cartridges.
Mounting System:
If using a quick-detach (QD) suppressor, make sure your gun can accommodate the required mounting system. By matching caliber, threading, barrel length, and pressure rating, you can be confident a suppressor will work with your firearm.
Sound Reduction
When selecting a suppressor, sound suppression is a critical factor, as it directly impacts the level of noise reduction and the overall shooting experience. While no suppressor can make a gun completely silent, most quality suppressors can reduce the sound of gunfire by 20 to 40 decibels. This reduction can significantly lower the risk of hearing damage and make shooting more comfortable.
Decibel Reduction:
Suppressors work by slowing down and cooling the escaping gases after a shot is fired, reducing the noise. The amount of sound reduction varies between models and calibers, but generally, a suppressor can bring gunfire down from levels of 160-170 decibels (which can cause instant hearing damage) to around 130-140 decibels, similar to the sound of a jackhammer or loud music.
Comparing Models:
When researching suppressors, it's important to look for published decibel reduction stats from manufacturers, which provide a general idea of performance. Some suppressor brands, like SilencerCo, publish detailed testing results. However, the real-world performance of a suppressor may vary due to factors like:
- Ammunition type: Subsonic rounds will be quieter than supersonic rounds.
- Barrel length: Shorter barrels often produce louder shots, affecting suppression.
- Environmental factors: Weather, altitude, and shooting conditions can influence the sound.
Balancing Sound Suppression and Size:
Suppressors with better sound suppression tend to be larger and heavier, which can impact handling and balance. If maximum sound reduction is important to you, especially for hunting or range use, opting for a slightly larger suppressor may be worth the trade-off. However, for tactical or home-defense scenarios, you might prefer a more compact suppressor that sacrifices a bit of sound suppression for ease of use.
In summary, understanding the decibel reduction stats and the variables affecting sound suppression will help you choose the right suppressor for your needs, ensuring both effective noise reduction and optimal performance.
Purpose
When choosing a suppressor, it’s important to consider the intended use for your firearm. Different situations may require different features to optimize performance:
-
Hunting: For hunters, a lightweight suppressor is ideal since it won’t significantly impact your rifle’s handling, balance, or weight during long treks. Compact models can also reduce bulk, making it easier to maneuver in tight spaces like dense woods. Additionally, sound suppression helps avoid spooking nearby game.
-
Range Use: If you plan to use your suppressor primarily at the shooting range, durability becomes a key factor. Suppressors designed for heavy use and frequent firing are better suited for this, as they can withstand the high heat and wear from long sessions. Many range-specific suppressors are built from strong materials like stainless steel or Inconel.
-
Home Defense: For home defense, size, sound suppression, and ease of attachment are crucial. You’ll want a compact suppressor that balances quick handling with effective noise reduction to minimize hearing damage in enclosed spaces. A suppressor that attaches quickly and reliably—such as a quick-detach model—ensures you’re ready for urgent situations.
By considering your specific needs, whether it's portability for hunting, durability for range use, or practicality for home defense, you can choose the right suppressor to match your gun’s purpose.
Legal Considerations
When purchasing a suppressor, it's essential to check local laws, as suppressor ownership and usage can be restricted or heavily regulated in certain states. Although suppressors are legal under federal law and regulated by the National Firearms Act (NFA), individual states have their own laws governing their possession, sale, and use. Here's what you need to know:
State-Specific Restrictions:
-
Banned States: Some states, like California, New York, New Jersey, Illinois, and Hawaii, outright ban civilian ownership of suppressors. In these states, it is illegal to buy, possess, or use a suppressor, regardless of federal approval.
-
Hunting Laws: In some states, suppressor ownership is allowed, but their use for hunting is restricted or prohibited. For example, while suppressors are legal in Connecticut, they cannot be used for hunting. On the other hand, states like Texas and Georgia allow suppressor use for hunting.
-
Additional Paperwork: Even in states where suppressors are legal, there may be additional state or local registration requirements beyond the federal ATF process. You may need to submit local applications, provide fingerprints to local authorities, or notify law enforcement officials.
Transport and Use:
Even if you legally own a suppressor in one state, transporting it across state lines could become an issue. You must ensure that suppressors are legal in any state you plan to travel to. Crossing into a state with stricter laws could result in legal consequences, even if the suppressor is legally owned in your home state.
Compliance with Federal Law:
Owning a suppressor requires compliance with federal regulations, including completing the ATF Form 4, paying a $200 tax stamp, and undergoing a background check. Local laws cannot override these federal requirements, but they can add additional restrictions or outright bans.
Staying Informed:
Because laws can change, it’s crucial to stay updated on current regulations in your state. Check with your local law enforcement or legal professionals before purchasing or transporting a suppressor.
By understanding the local laws and ensuring compliance with both state and federal regulations, you can avoid legal issues and enjoy the benefits of suppressor ownership where allowed. Learn more on the American Suppressor Association website.
