The NFA, Suppressors, and You

When considering purchasing a suppressor for your AR-15, it’s essential to understand the National Firearms Act (NFA) and the associated requirements. Introduced in 1934, the NFA regulates the ownership, transfer, and manufacturing of certain firearms and firearm accessories, including suppressors. Navigating these regulations may seem complex at first, but with a little guidance, you can comply with the law while enjoying the benefits of a properly registered suppressor.

What is the NFA?

The National Firearms Act was designed as a federal law to regulate specific categories of firearms and accessories that were deemed to require additional oversight. Suppressors (also known as silencers) fall under this category due to their potential impact on noise suppression. The law includes strict guidelines for transferring or owning such items.

• Registration: All suppressors must be registered with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
• Tax Stamp Requirement: A $200 tax stamp must accompany each suppressor purchase.
• Background Check: Buyers must undergo an extensive background check.
• Form 4 Submission: Individuals purchasing from a dealer must submit ATF Form 4 along with fingerprints and passport photos.
• Wait Times: Processing times can range from several weeks to months depending on ATF backlog.

Steps to Legally Acquire a Suppressor

1. Find a Licensed Dealer
   Locate a Federal Firearm Licensee (FFL) who is also qualified as a Special Occupational Taxpayer (SOT). They can guide you through the process of selecting and purchasing your desired suppressor.
2. Complete ATF Form 4.
3. Provide two fingerprint cards (done by local law enforcement or authorized service).
4. Include two recent passport-sized photos.
5. Pay the Tax Stamp Fee
   Pay $200 for each suppressor you intend to purchase. This is non-refundable but necessary for legal compliance.
6. Wait for Approval
   Once your paperwork is submitted, anticipate waiting several months for processing by the ATF before taking possession of your AR-15 suppressor.
7. Take Possession After Approval
   Once approved, you’ll receive your tax stamp along with authorization allowing you to collect your suppressor from your dealer.

Benefits of Compliance

• Reduces potential legal risks or penalties associated with unregistered ownership.
• Peace of mind knowing you’re operating within federal guidelines.
• Accessory transfers become simpler if both parties comply with these regulations.

Despite these challenges, our process ensured objective data collection and practical insights into each suppressor’s real-world performance.

How We Tested AR-15 Suppressors

When reviewing AR-15 suppressors, particularly those designed for 5.56 and multi-caliber use, a thorough and standardized testing process is critical. This ensures that performance metrics are objectively measured, allowing shooters to make informed decisions based on real-world results rather than marketing claims. Below is an overview of the methods and criteria used during our testing.

Key Testing Criteria

• Sound Suppression: The primary purpose of a suppressor is to reduce the sound signature of a firearm. Using calibrated decibel (dB) meters, we measured the reduction in noise levels at both the shooter’s ear and muzzle point.
• Durability and Heat Resistance: Suppressors endure extreme stress due to high temperatures generated by repeated firing. We evaluated materials (e.g., titanium, stainless steel, or aluminum), tested heat build-up after successive shots, and inspected for structural integrity post-testing.
• Impact Shift: We assessed how attaching the suppressor affected bullet trajectory by comparing groupings with and without it installed on the rifle. Minimal impact shift was preferred for maintaining point-of-aim consistency.
• Weight and Balance: Suppressors vary significantly in weight, which can affect the handling characteristics of your rifle. Heavier models may reduce maneuverability, whereas lighter ones might sacrifice durability.
• Ease of Installation: A quality suppressor should be simple to mount securely while staying compatible with popular AR-15 muzzle devices such as flash hiders or compensators.

Our rigorous testing methodology ensures that only top-performing AR-15 suppressors make the final list while providing readers with reliable insights into their strengths and weaknesses.

How We Tested AR-15 Suppressors

When evaluating AR-15 suppressors, precision and consistency are key to determining their performance. Testing isn’t just about attaching a suppressor and firing a few rounds; it’s a comprehensive process that takes into account various factors such as sound reduction, build quality, durability, and compatibility with different ammunition types. Here’s an in-depth look at how we tested the suppressors on this list.

Key Factors Considered During Testing

1. The primary purpose of a suppressor is to reduce the decibel (dB) levels of gunfire for both shooter comfort and hearing protection.
2. Using sound meters placed at the shooter’s ear and muzzle position, we measured the actual dB reduction for each suppressor.
3. Suppressors were tested with both supersonic and subsonic 5.56 NATO rounds to assess performance across ammunition types.
4. Suppressors endure extreme heat and pressure during use, so we tested them under sustained fire conditions.
5. Each model was subjected to rapid-fire scenarios (magazine dumps) to evaluate its ability to handle heat without warping or degradation in performance.
6. Materials like stainless steel, titanium, or Inconel were closely examined for their resistance to wear over time.
7. We assessed whether each suppressor disrupted the balance of an AR-15 when attached.
8. Lightweight suppressors were checked for maintaining maneuverability without compromising suppression capability.
9. The simplicity of attaching or removing each unit was evaluated. Quick-detach (QD) systems were compared to direct-thread models for ease-of-use in field conditions.
10. Compatibility with common muzzle devices such as flash hiders or compensators was also considered.
11. To ensure no significant shift in point-of-impact (POI), each suppressor was tested using bench-rested rifles before attachment and after installation.
12. POI shifts larger than one MOA (Minute of Angle) were flagged as potential drawbacks.
13. Functionality relative to cost is always important. We balanced premium features against price points to provide recommendations that fit varying budgets.

Test Environment

Our tests were conducted on outdoor ranges under controlled conditions:
– Temperature: Between 60–80°F, ensuring consistent results unaffected by extreme cold or heat. – Distance: Firing tests included both short-range (25 yards) for immediate accuracy checks and mid-range (100 yards) evaluations for POI persistence. – Ammunition: Both standard M193 55-grain FMJ rounds and heavier 77-grain OTM loads were used during testing.

Performance Metrics Table

Test Metric	Weight (%)	Top Performer Example
Sound Suppression	40%	ABC Model
