Myth #1: Suppressors Make Guns Completely Silent (Movie-Quiet)
Perhaps the most pervasive myth comes straight from Hollywood action movies. We’ve all seen scenes where assassins fire weapons with barely a whisper—a tiny pfft sound that draws no attention. This single image has shaped decades of suppressor misunderstanding. The myth is so powerful that many shooters assume suppressors are banned because they’re too effective at concealment, when the opposite is true.
The truth: Suppressors are nowhere near silent. Even with subsonic ammunition—the quietest possible loading—a suppressed centerfire rifle or handgun still produces 120-140 decibels of sound. To put that in perspective, a chainsaw at full throttle is about 120 dB. A suppressed .22 LR with subsonic ammo might reach 117-122 dB, which is genuinely impressive, but it’s absolutely not the whisper you hear in films. The acoustic signature is still immediately recognizable as a gunshot to anyone who has heard one.
Why the confusion? Suppressors do reduce noise significantly. A typical sound reduction ranges from 20 to 35 decibels depending on caliber, ammunition, and suppressor design. That’s substantial—roughly half the perceived loudness. But the starting point matters critically. An unsuppressed rifle like a .308 Winchester creates roughly 165-170 dB. Reduce that by 30 dB and you’re at 135-140 dB—still loud enough to damage hearing without ear protection. An unsuppressed 9mm handgun reaches 160 dB; suppressed, it’s 130-135 dB. The reduction is real and audible, but the result is still definitely loud.
How Suppressors Actually Work
Suppressors reduce noise by expanding hot, high-pressure gases exiting the muzzle. Instead of releasing all that energy in one violent pulse, a suppressor divides the gases into expansion chambers, slowing their release. This gradual expansion reduces the acoustic shock wave that creates the “bang” sound. The principle is real and effective, but the laws of physics prevent silent operation. Each baffled chamber absorbs some energy and muffles the sound wave, similar to how a car muffler works.
The engineering is sophisticated: modern suppressors feature precisely designed baffles that create turbulence and pressure reduction without disrupting the bullet’s flight path. Some suppressors use monocore designs with a single expansion chamber. Others use multi-baffled designs with 5-8 separate expansion stages. The BANISH suppressor line uses advanced baffle geometry optimized for each caliber range.
The real benefit shows up in hearing protection. A suppressed shot with subsonic ammunition—particularly in .22 LR—approaches the OSHA safe exposure threshold of 140 dB for impulsive sounds. Many shooters can use suppressors with hearing protection and experience minimal hearing fatigue, compared to unsuppressed shooting where ringing ears persist for hours and potential hearing damage accumulates. Even centerfire suppressors, while louder, still provide substantial hearing protection when combined with earplugs or earmuffs.
Myth #2: Suppressors Are Illegal or Extremely Hard to Obtain
For decades, suppressors carried a mystique of illegality and danger. Part of this comes from federal regulation—suppressors are NFA (National Firearms Act) items, like machine guns and short-barrel rifles. The other part comes from outdated legal information that hasn’t caught up with recent changes. Many gun owners erroneously assume suppressors are banned at the federal level or require special licenses unavailable to civilians.
The truth: Suppressors are completely legal in 42 states, and the legal landscape improved dramatically on January 1, 2026. The One Big Beautiful Bill Act eliminated the $200 federal NFA tax stamp—the most significant suppressor law change in decades. Previously, buying a suppressor meant paying $200 in federal excise tax plus the suppressor purchase price, then waiting 6-12 months for federal approval through a paper Form 4 process. Now you only pay the suppressor price—typically $300-$1,200 depending on design and materials—and the approval process takes 30-90 days via the faster ATF eForm 4 electronic system.
Consider the practical impact: a shooter interested in three different suppressors (one for .22 LR, one for 9mm, one for .308) previously spent $600 in combined tax. Now they don’t. A multi-caliber suppressor that previously cost $1,100 plus $200 tax ($1,300 total) now costs $1,100. This 15-20% price reduction removes a significant barrier to ownership.
Silencer Central handles all NFA paperwork for customers in 42 states, making the process straightforward and transparent. No special license is required beyond what any firearm purchaser undergoes. No local permit is needed in most states. The background check you undergo for NFA registration is the same check any licensed dealer conducts for standard firearm purchases—just slightly more thorough because NFA items receive additional ATF scrutiny.
State-Level Legality Varies
Eight states restrict or ban suppressors entirely: California, Delaware, Illinois, New Jersey, New York, Rhode Island, Vermont, and Washington D.C. Most other states place no additional restrictions beyond the federal NFA process. Some require a state permit in addition to federal registration—typically just filing paperwork with a local sheriff’s office. Others allow suppressors with zero additional state requirements. Silencer Central can guide you through your specific state’s requirements—that’s why they operate in exactly 42 states where they can legally deliver suppressors directly to customers.
The myth persists because outdated websites and forums still mention the $200 tax and multi-year wait times. News articles from 2024 and earlier discuss the old system. Social media comments from users who purchased suppressors years ago reflect their outdated experience. But that information is now completely obsolete for most buyers in legal states. Someone buying their first suppressor in 2026 will have a dramatically different experience than someone who bought in 2025.
For shooters in the 42 legal states, the current process is relatively simple: find a dealer like Silencer Central, select your suppressor, complete the eForm 4 online with fingerprints, and wait 30-90 days for ATF approval. That’s genuinely accessible and nothing like the complex process of 5-10 years ago.
Myth #3: Only Criminals and Assassins Use Suppressors
Action movies and crime dramas have created an association between suppressors and villainous intent. This reinforces a perception that only people with illicit purposes would own one. This misconception is perhaps the most damaging because it colors public perception and has influenced some politicians’ positions on suppressor regulation.
The truth: Suppressors are standard equipment in the military, law enforcement, and civilian hunting and sport shooting communities worldwide. In fact, most major firearms-producing nations consider suppressors standard hearing protection rather than tactical accessories.
Military and Law Enforcement: The U.S. military has issued suppressors to special operations units and conventional infantry for decades, not for covert assassination, but for hearing protection during extended operations and training. Troops wearing suppressors on their rifles while patrolling in Iraq and Afghanistan were protecting their long-term hearing, not conducting silent operations. Law enforcement agencies including the FBI, DEA, and ATF use suppressors during firearms training to reduce occupational hearing loss—a significant issue for law enforcement given their career-long exposure to high-noise weapons training.
Federal marshals, DEA tactical teams, and FBI hostage rescue teams all use suppressed firearms. Not because suppressors are somehow undetectable, but because suppressors reduce hearing damage during high-stress tactical training and operations. Even in military applications where stealth matters, suppressors are only one tool among many—they reduce signature but don’t eliminate it.
International Perspective: In New Zealand, the United Kingdom, France, Germany, Scandinavia, and most of Europe, suppressors are treated as hearing protection devices, not specialized tactical equipment. Many European hunting associations actively encourage suppressor use to reduce noise pollution and hearing damage. In some countries, hunters are expected to use suppressors as responsible stewardship—reducing unnecessary noise that disturbs others and wildlife. Germany requires hunters in some regions to use suppressors. This regulatory approach reflects viewing suppressors as environmental and occupational safety equipment.
Civilian Users: Today’s suppressor owners span enormous demographics. Farmers reduce noise pollution on their property when shooting predators or groundhogs—suppressors prevent disturbing neighbors and livestock. Hunters protect their hearing while stalking game—hunting seasons are long, shooting can be repetitive, and hearing protection is practical. Sport shooters competing in 3-gun, benchrest competitions, and tactical shooting matches use suppressors for hearing protection during high-round-count events. Hearing-conscious recreational shooters at ranges use suppressors because they enjoy shooting without permanent ringing in their ears. Firearms instructors conducting training courses use suppressors because they’re responsible for their students’ long-term hearing health. Gun owners with sound-sensitive family members use suppressors to reduce household noise during backyard range sessions. Shooting range operators use suppressors to reduce neighbor complaints and meet noise ordinances.
These users span every socioeconomic bracket and political affiliation. They include nurses, teachers, engineers, construction workers, retirees, active-duty military, law enforcement officers, hunters, competitors, and casual shooters. The one thing they have in common isn’t criminal intent—it’s hearing protection and noise responsibility.
Myth #4: Suppressors Slow Bullets Down (Reduce Velocity)
This misconception stems from intuitive thinking: if a suppressor creates back-pressure by resisting gas flow, wouldn’t that pressure push back on the bullet and slow it down?
The truth: Suppressors have essentially no effect on bullet velocity. The reason is straightforward: when a bullet reaches the muzzle and enters the suppressor, it’s already traveling at its final velocity. The bullet’s speed is determined entirely by the powder charge and barrel length. By the time gas expansion chambers exert any resistance, the projectile is already downrange.
Chronograph testing proves this. A .308 Winchester round fired through a BANISH suppressor leaves the muzzle at the same velocity whether suppressed or unsuppressed. Any variation you might measure (within 10-20 fps) falls within normal shot-to-shot velocity variation caused by powder burn rate and ambient temperature.
Ballistic Implications
Because suppressors don’t slow bullets, point-of-impact shifts slightly due to the weight and mass of the suppressor changing the barrel’s vibration characteristics. This is typically only 1-3 inches at 100 yards and is easily compensated with a rifle’s existing adjustment mechanisms. Many shooters re-zero their rifles after mounting a suppressor and never think about it again.
The bottom line: suppressors don’t compromise ballistic performance. Your favorite hunting load shoots the same way suppressed as it does unsuppressed.
Myth #5: You Need a Special License to Own a Suppressor
Suppressors fall under the National Firearms Act, which also regulates machine guns, short-barrel rifles, and destructive devices. That federal regulation creates a perception that special licensing is required.
The truth: No special license is required. The NFA registration process is straightforward: you submit an eForm 4 with your fingerprints and background check, the ATF reviews your application (30-90 days), and upon approval, you’re registered as the suppressor’s owner. That’s it. No additional state licensing, no local permits in most jurisdictions, no special background check beyond what a licensed dealer already conducts.
Think of it like this: the NFA process replaces the firearm dealer’s background check, not something on top of it. You’re not getting a “suppressor license”—you’re just being registered as the legal owner of an NFA item, similar to how the government registers vehicle ownership.
Myth #6: Suppressors Are Only for Rifles
Many shooters assume suppressors are specialized accessories for serious hunters or tactical operators. In reality, suppressors are made for every firearm type and caliber.
The truth: Suppressors are manufactured for:
- .22 LR and rimfire: Entry-level suppressors ranging from $300-600, perfect for plinking and training
- 9mm and other handgun calibers: Pistol-dedicated suppressors like the BANISH 9 (Silencer Central) ($500-800) that mount via threaded barrels
- .45 ACP: Larger suppressors like the BANISH 45 (Silencer Central) that handle subsonic .45 ACP loads beautifully
- Centerfire rifles (.223, .308, etc.): Multi-caliber suppressors like the BANISH 30 Gold (Silencer Central) handle multiple calibers on one suppressor
- Magnum calibers (.300 Win Mag, .338 Lapua): Heavy-duty titanium suppressors like the BANISH 338 (Silencer Central) rated for the highest pressures
- Shotguns: Specialized suppressors for 12 gauge and 20 gauge shotgun shooting
The most popular choice for many shooters is a multi-caliber suppressor like the BANISH 46 V2 (Silencer Central), which handles everything from .223 to .308 with a single mount and chamber. This versatility means one suppressor can serve multiple rifles in your safe.
Myth #7: Suppressors Require Constant Maintenance and are High-Maintenance
Some shooters hesitate to buy suppressors because they imagine constant cleaning and specialized maintenance.
The truth: Modern suppressors, particularly sealed centerfire designs, are remarkably low-maintenance. Sealed monocore suppressors like BANISH centerfire models require virtually no cleaning for centerfire ammunition. The baffles are internal, sealed chambers resist fouling, and for most shooters, a suppressor bought today will outlast the barrel it’s attached to.
Rimfire suppressors (.22 LR) do require periodic cleaning because rimfire ammunition generates significantly more lead fouling inside the suppressor. Most rimfire shooters clean their suppressor every 500-1,000 rounds, a 15-minute process with a small rod and patches. This is a minor inconvenience compared to the hearing protection benefit.
Lifetime Warranty
BANISH suppressors come with lifetime manufacturer warranties. That means if anything fails due to defect, it’s replaced or repaired free, forever. You’re not buying a consumable accessory—you’re buying a permanent part of your shooting kit that will likely outlast multiple rifles.
Myth #8: Suppressors Create Excess Back-Pressure That Damages Guns
Some believe that by resisting gas flow, suppressors create harmful back-pressure that accelerates bolt wear, damages extractors, or degrades reliability.
The truth: Modern firearms are designed to handle the minimal back-pressure created by suppressors. Military rifles have run suppressed for decades without reliability issues. The back-pressure from a suppressor is negligible compared to the normal pressure of ammunition firing. In fact, suppressor-equipped rifles often run slightly softer than unsuppressed because the suppressor absorbs some recoil energy, resulting in less violent bolt cycling.
The only consideration: direct-impingement .223 rifles (like the AR-15) may run slightly slower with a suppressor because of the minute back-pressure increase. Some shooters adjust their buffer weight or tune their gas port, but it’s entirely optional and not necessary for most users.

Frequently Asked Questions
Can you really use a suppressor to eliminate the sound of a gunshot like in movies?
No. Even the quietest suppressors with subsonic ammunition produce 117-122 dB of noise for .22 LR, and 125-140 dB for larger calibers. That’s still dangerously loud—equivalent to a chainsaw, jack hammer, or rock concert. Suppressors reduce noise, they don’t eliminate it. Hollywood’s silent “pffft” is pure fiction and misleads audiences about suppressor capabilities.
Did the One Big Beautiful Bill Act really eliminate the $200 NFA tax stamp?
Yes, effective January 1, 2026. The One Big Beautiful Bill Act eliminated the $200 federal excise tax on NFA items including suppressors, machine guns, and short-barrel rifles. Now you only pay the suppressor’s purchase price (typically $300-$1,200) and complete the NFA registration process (30-90 days). This is the biggest suppressor law change in decades and makes ownership significantly more affordable.
Are suppressors used by the military and law enforcement?
Absolutely. The U.S. military has issued suppressors to special operations units and standard infantry for hearing protection for decades. Federal law enforcement agencies including the FBI, DEA, and U.S. Marshals Service use suppressed firearms during tactical operations and training. Suppressors are standard hearing protection equipment, not covert assassination tools.
What happens if I attach a suppressor to my rifle—does the point of aim change?
Yes, slightly. Adding a suppressor changes the barrel’s vibration characteristics, typically shifting impact point by 1-3 inches at 100 yards. This is easily corrected by re-zeroing your scope or sights after mounting a suppressor. Many shooters find that adjusting elevation 2-4 clicks on their scope dial resolves the shift entirely.
Do sealed suppressors like BANISH require regular cleaning?
Sealed centerfire suppressors rarely require cleaning. You can shoot thousands of centerfire rounds through a BANISH centerfire suppressor without maintenance. Rimfire suppressors like the BANISH .22 require cleaning every 500-1,000 rounds due to lead fouling from rimfire ammunition. BANISH suppressors come with lifetime warranties, so even maintenance is covered.
