Legalities & FAQsSilencers (or suppressors, which is really the more correct term), fall under the National Firearms Act (NFA) of 1934. This means they are legal for ownership by civillians in most states, but you have to pay the Government a one time transfer tax of $200 and undergo a background check to exercise your Constitutional Right.
STEP 1: Ensure the item you want is legal in your state. Some states ban all NFA weapons, and some states simply ban certain types. If you live in California, Hawaii, Iowa, Illinois, New Jersey, New York, Massachusetts, Rhode Island, or Vermont, you cannot own a suppressor. Do not attempt an “under the table” purchase, as any attempt to do so is soliciting a felony.
STEP 2: Contact a local Class 3 dealer or Class 2 manufacturer and find out what needs to be done in your state to purchase an NFA item. If you don’t know a dealer that has the proper license (not just any FFL can do this) we may be able to provide a recommended dealer.
( NOTE: YOU do not generate the Form 4, Application for Tax paid Transfer, your DEALER generates this form and gives it to you once he has the suppressor in his possession.)
STEP 3: Send us your payment before we ship the suppressor to your dealer. SRT Arms is not a cash and carry business and does not accept COD.
STEP 4: Please be patient. We typically start the paper work to transfer to your local dealer within 1-2 weeks of receipt of funds. That paperwork takes about 4 weeks to clear, then we send your suppressor to the local dealer (who typically will charge you a nominal transfer for his trouble and storage of your gun/suppressor). At that time he will give you the Form 4s, fingerprint cards, etc, and you get them filled out, and send them into ATF with your $200. Some dealers will have you give the forms back to the dealer with your $200 check, and they will send it in. About 3-5 months after that, the ATF will send an approved Form 4 back to your local dealer, and you will get your suppressor.
STEP 4 Info: Effective the first of July, 2016, Chief law Enforcement Officer signoff is no longer required, and will be replaced by Chief law Enforcement Officer Notification. This applies to individual transfers as well as Trusts and Corporations, where all responsible parties of the trust and Corporations will need to get fingerprinted and photographed and submitted with the Form 4 application just like an individual transfer, but the CLEO signoff requirement has been removed. You will be required to NOTIFY the CLEO of your intent to transfer however, but they need to take no action unless they have knowledge your intent to transfer would be in violation of the law.
Frequently Asked Questions
Why does only the Comanche come apart for cleaning and the other suppressors are sealed?
There is no free lunch, take apart suppressors are usually louder than sealed units, and in most cases, so called take apart cans that are as quiet as sealed units, will only come apart when they are clean. Once you fire a 100 rounds through them, you can’t get them apart; the complexity that makes a can quiet, means it cannot be easily disassembled, and since reassembly orientation is critical to optimize suppression, incorrect reassembly can cost several db.
Won’t my suppressor clog up if I can’t clean it?
Generally, no. However, a .22 rimfire can, fired on a short barrel pistol, will need a rebuild after 10,000 – 12,000 rounds, and we offer this service for a nominal charge. Centerfire rifle cans are self cleaning (our cans are, anyway) and the residue blasts loose after it builds up more than a several thousandths of an inch, due to high pressures involved. Our pistol caliber centerfire integrals have enough volume inside that expected life is 80,000 rounds before they require a factory rebuild.
Can you make your stainless rifle cans lighter to match some of your competitors?
We certainly could–but suppressor longevity would be compromised. Ultra lightweight, stainless suppressor tubes will often start to bulge at the baffles after heavy use (our tubes won’t, even when used on many cartriges beyond what they are designed for. Since a new tube/serial number to replace a bulged can will cost you another $200 tax stamp, we decided to make our cans more robust, even if it meant adding a few ounces. If light weight is important to you, you should consider a Titanium can, they are half the weight and stronger yet than stainless cans. Our suppressors can often have the baffle stack replaced at the factory if needed–fully welded suppressors cannot, and will cost you another $200 tax stamp.
I live in Arizona, can I buy direct from SRT Arms or do I have to go through a dealer?
You may buy directly from us, but you will need to drive to our location in Camp Verde to pick up the can when the paperwork is approved.
Can I start the transfer of paperwork from my local dealer to me before you have shipped the suppressor to him?
Generally, no. Your dealer needs to have the suppressor in his possession prior to signing and dating the form 4. However, on longer lead items like our Integral suppressors, if time is critical, and if you don’t mind paying a little extra for the shipping, we can ship a registered tube to your dealer as soon as the dealer transfer paperwork is approved, and then the dealer can get your paperwork started, then either the dealer or you can ship the tube back to us to be finished.
Will your .30 can work on .223? How about using a .223 can on a .22?
Yes–either will work just fine. We make adaptors to allow the 5/8″-24 threaded .30 can fit the 1/2″-28 .223 threads. The only disadvantage to using a .223 can on a .22 is the size and weight compared to a dedicated .22 can.
Why do your suppressors have larger bores through the baffles than a lot of other suppressors?
Many manufactures use real tight bores to make their cans a few db quieter than what they would otherwise be. The problem is that ALL bullets yaw somewhat upon leaving the barrel of the gun, so that the bullets have a slight sideways angle to them, too tight of a bore can cause baffle strikes, and even the slightest baffle strike will cause the bullet to hit anywhere from several inches, to several feet from where it was intended to hit. Do you want to take a chance on your bullets going someplace besides where you aim? And you aren’t sacrificing anything with our larger bores, as our cans are generally quieter than other cans with smaller bores anyway, due to our advanced baffle design.
Are there any cancellation fees if I need to cancel my order?
Yes, we have invested money in paperwork, dealing with the ATF and often work on the suppressor. Cancellation fees can range from 20% – 30%, depending on the overall cost of the order, and custom built units are non-cancelable.
How do I select the best suppressor for me?
You have really two choices to select from when you purchase a suppressor; a thread mount “muzzle” suppressor (can), or an integrally constructed suppressor where the can is built back over the barrel of the gun. Some handguns like the Beretta 92, and Browning Highpower must use muzzle cans, as there is no other way to suppress them. Most rifles can have either muzzles cans, or be integrally suppressed, as can some pistols like the Ruger MkII, Browning Buckmark, Hi-Standard models, and Colt Woodsman, and Thompson Contender. A removable muzzle can allows you to swap the can from gun to gun in same, or lesser calibers, as long as the muzzles are all threaded the same, but at the expense of added overall length to the gun. An integral will always be quieter than a muzzle can assuming both are from the same manufacturer, as the barrel can be ported to vent high velocity gas into expansion chambers, and then bleed the gas out slowly to the atmosphere. Typical examples of integral rifle applications are any bolt action rifle, and most any AR/M-16 style rifle. This allows a shorter overall package, but it is a permanent modification, you can’t just remove the suppressor and go back to unsuppressed shooting. Suppressing high velocity/high powered centerfire rifle cartridge, whether muzzle or integral, does nothing to silence the ballistic crack the bullet makes as it travels downrange far in excess of the speed of sound. It will remove most of the muzzle blast, which may let you shoot without ear protection if the db reduction is great enough, and will cloak your location from any outside parties, as they will hear the bullet, but it is difficult to tell where exactly the shot originated. Integrally Suppressed .22 Firearms: There are several things to consider when selecting integrally suppressed firearms, whether it is a Ruger MkII, or any other integrally suppressed .22 caliber gun. Ported barrels are used when maximum sound reduction is required. Some bullet velocity is lost, but if you select a well made gun, with proper porting, the velocity loss is minimal, but sound reduction is greatly improved. Our ported barrel guns have the highest muzzle velocity in the industry. Improperly designed ported barrel guns will usually not cycle when shooting high velocity, or standard velocity ammo, and certainly not cycle when shooting subsonic ammo. Well designed integrally suppressed pistols will cycle all ammo, including subsonic, yet provide better sound reduction than poorly designed guns that will not cycle any ammo. Many ported barrel guns lose so much bullet velocity from poorly designed porting, that you may be better off with a Crossman pellet rifle for serious pest removal applications. Always ask if the gun you are looking at will cycle standard velocity, and subsonic ammo. If you get an answer like “our customers prefer to shoot only CCI mini-Mag”, or “we recommend only Remington high velocity ammo” is a real good tip off that the manufacturer killed the bullet velocity to get decent suppression, and the gun won’t work reliably with anything else. Our guns cycle all ammo, High velocity, standard velocity, and subsonic **. Lets look at a comparison of the Sound-Master MkII and competitors product “A”. The Sound-Master metered 116 db with Remington Hi-vel ammo at 1040 FPS, 111 db with CCI Std vel ammo at 910 FPS, and 109 db with Remington subsonic at 820 FPS on one particular day. The Competitor metered 115 db at 910 FPS with Remington Hi-vel ammo, and wouldn’t reliably cycle CCI std vel ammo at 112 db at 760 FPS, and would not cycle at all the Remington subsonic at 110 db at 600 FPS. If you put the two guns side by side, you “might* hear the competitors gun is 1 db quieter shooting Remington Hi-velocity, but it has a lot slower bullet. Or you just take the Sound-Master, shoot CCI std vel ammo, and you now have the same bullet velocity (910 FPS), and the Sound-Master is much quieter than the competitors gun comparing bullet velocities. You, with the Sound-Master have the choice of selecting the proper ammo for the occasion; casual plinking, or ultimate stealth. The owner of the competitors gun is stuck with just high velocity ammo, unless he wants to manually cycle the gun all the time. Another consideration is whether you want a stainless steel gun, or a blued/parkerized gun. Stainless is a must for use of water as a suppression enhancer, and desirable for ease of cleaning in general. Blued or Parkerized guns are desirable where the reflectivity of stainless steel would be a liability. Another important consideration is whether of not the suppressor removes from the gun for cleaning. Obviously, a .22 caliber suppressor the can be easily removed by the owner, will last a lot longer that one that is permanently fixed to the gun. If the suppressor does not remove from the gun, make sure that the expansion chamber area around the barrel has some method of draining cleaning solvent from the chamber. A non-drainable, non-removable suppressor, quickly become clogged, and useless, especially considering how dirty most .22 ammo is. At $200 for the tax stamp, plus the cost of the gun, I am sure you donâ€™t want to throw your gun away after 5,000 rounds or so because the suppressor has become clogged, and quite loud. Well designed guns with removable suppressors have a good indexing feature that allows the suppressor to be aligned properly on the gun each time it is removed. Our tensioned barrel design promotes ultimate accuracy. We, at SRT Arms Division, offer Ruger MkIIIâ€™s, in both stainless, and blued steel. All of our suppressors are designed for easy removal from the gun, and offer the best suppression currently available. Barrel Threading and Muzzle Cans Obviously, a screw on muzzle can has to attach to the barrel somehow. This means a threaded barrel is required either for the can to screw directly on to the barrel, or to screw on a quick attach coupling device for the suppressor. On a gun with a factory flash hider, like an AR-15 or M-16, threads already exist. If threads are not present, then the barrel must be threaded. You should always have the manufacturer of the suppressor do the barrel threading if it is required, so he can guarantee alignment/straightness of the threads, and be able to warrantee the suppressor. Threads MUST be turned on a lathe; the threading *kits* sold to do-it-your-selfers will result in non-concentric, non parallel threads, and cause bullet/baffle strikes and damage the suppressor. If your suppressor manufacturer can’t or won’t thread barrels, he shouldn’t be in the suppressor business. We offer barrel threading services at a reasonable price, which ranges from $50 to $125 depending on the complexity of the job, and whether or not a thread protector must be supplied to cover the threads when the suppressor is not on the firearm. Myths and Reality A suppressor does not make a gun absolutely quiet, no matter what someone may have said once. Suppressor designs have progressed to the point that a good suppressor is almost *Hollywood Quiet*, at least with subsonic low power ammo like .22 RF and in some cases, larger subsonic pistol calibers. If anyone tells you: “all you hear is the action noise”, they are either exaggerating; or they are deaf. A good suppressor allows you to HEAR the impact of the bullet on the target and HEAR the noise of the action cycling, (if for no other reason, the action is often right next to your face when sighting the gun, and since the muzzle of the gun is farther in front of you, it sounds diminished to you, the shooter). But to a person standing to the side, he will hear some muzzle report, though it does not sound like a gunshot, but rather just a fast whoosh of air, when using a good suppressor. Some may think a bolt action gun, say a Ruger 77/22 is quieter than a semi-auto 10/22 when both are suppressed. To you, the shooter, the 77/22 is quieter because you don’t hear the bolt slap right next to your ear, and you don’t hear any gas escape out the open ejection port during cycling as with the 10/22. But, If you are standing 50 feet away, the guns sound identical, as the suppressed muzzle report is just slightly louder than the semi-auto action. What a good suppressor does allow you do is shoot comfortably without using ear protection, alters the sound of the gunshot, so it sounds like *something*, but not a gun, and greatly reduces the distance at which people can hear you shooting. An unsuppressed .22, for example, can be heard for up to a mile, a suppressed .22, can often not be heard 50 yards behind the shooter, and only somewhat further to the side. Decibels, or db, What Do They Mean To Me? There has been a proliferation of highly affordable sound suppressors, some of which work well and some of which have really poor performance. With rare exceptions, few have been measured for suppressed sound levels. There are those that say that actual reduction (or absolute sound level) measurements are not meaningful and that all that counts is the perceived loudness. Nothing could be further from the truth, and believing this fallacy can lead to significant hearing loss. Perceived loudness depends on two factors: the frequency of the sound itself and the observer’s existing degree of hearing loss. Regardless of how quiet something sounds, significant hearing damage can be sustained by gunfire. Further, hearing damage is caused by more than just gunfire, and the dose is cumulative. Other sources are industrial noise, wind noise (motorcycles, driving with the window open), entertainment, etc. Both OSHA and MIL-STD-1474D state that hearing protection MUST be used if the sound pressure levels of firearm noise are 140 dB or greater. This is specified in Requirement 4 of MIL-STD-1474D. While it is true that a sound level of 145 dB is not nearly as harmful as one of 160 dB, exposure will still cause damage. Once the damage has occurred, it is forever and will not come back. Further, MIL-STD-1474D has specific requirements for metering equipment, which eliminates the Radio Shack types of meters. The standard location for sound measurement is 1 meter to the left of the muzzle at 90 degrees to the bore axis and 1.6 meters above grass. This is the location that most in the US use. A second location, which is used to simulate the shooter’s ear, is 1 meter from the muzzle at an angle back from the bore axis of 45 degrees. Experience shows that this second location is 1-2 dB less than the one at 90 degrees. When measuring actually at the shooter’s ear location, there is too great a chance for some shadowing by portions of the shooter’s head, and drops of 4-5 dB suggest that this has happened. Regardless, the OSHA and MIL-STD requirements are for sound levels measured at the specified locations, not some other location. There are also some so-called independent websites that claim to test suppressors. Take these sites with a grain of salt, as they do not use Mil-Std 1474D test protocol, and use the wrong testing equipment. In some cases, the test results have been changed after the original posting, for whatever reason. In other words, they are not trustworthy results, and produce wildly incorrect db readings that no one else in the industry can duplicate. ALL of our suppressors, including the .223 and .308 cans measure well below the 140 db OSHA allowable limit for gunshots. If a suppressor manufacturer can’t prove their product is below 140 db, , you are possibly putting your hearing at risk. SRT sound tests and sound measuring equipment comply fully to MIL-STD-1474D. (Special Thanks to Dr. Phil Dater of Gemtech for his work, insight, and dedication to education about sound testing, and hearing loss, from which he has allowed our use of his research as written in the section above). You Get What You Pay For, To A Point A suppressor is a considerable investment; especially considering the extra $200 for the tax stamp, and the work involved with getting a CLEO signoff, and doing all the paperwork. There are a few suppressor manufacturers out there offering product that is priced at 20% to 30% the going rate from a major manufacturer. After you look around, you will find that most of the major manufacturers are usually priced within 20% of each other, with a few suppressor manufacturers offering product much cheaper, and some that are mighty proud of their products. There is a reason for this: Inexpensive product is either loud, very large dimensionally, or made of inferior materials like muffler tubing, fiberglas stuffing and freeze plugs, and the inexpensive manufacturer has no access to testing equipment to actually verify the performance of a product. They also typically are in business for only a few years, and after they found out they haven’t made any money selling stuff cheap, they go out of business—usually taking a lot of deposits from customers who will never get their product, along with them. On the other hand, some manufacturers that price their MkII’s, for example, at over $1000, are either paying for a lot of fancy advertising with your money, or they really don’t want to be bothered with making MkII;s, and figure if you want to pay a premium for something that isn’t any better than the midprice manufacturers offer, they will be happy to take your money. Buying the right product the first time, means much better long term satisfaction. We have been in business over 15 years, and offer quick turn around on your order; no need to wait for many months, years, or possibly forever to get your purchase. We offer a lifetime materials and workmanship warranty on our suppressors, which means if anything fails, we fix it free. If something beyond our control happens, like someone tries to shoot a 9MM slug through a .223 can, or the can is run over by a truck, we offer inexpensive repair or replacement. Repairs are typically $75-$125; a complete replacement, with the same serial number on a new tube (we can only do this with cans SRT made), is in the $200 range, depending on the can. This helps protect you, and helps cover our material costs, and saves your tax stamp. Summary We hope you appreciate us giving you the straight scoop. No fancy sales come-ons, no hyperbole. We just want you to be happy with the product you select, and to know it’s uses and purposes. If you have any questions, please contact us, we will be happy to go over your suppressor requirements with you. ** Some Federal ammo, and some Winchester ammo uses a real slow burning powder that won’t cycle any short barrel gun, ported or not. For that reason, we recommend all Remington, all CCI, and many specialty subsonics such as RWS for use in suppressed guns, ours or anyone else’s, as they burn cleaner in a suppressed firearm.
We warrantee our suppressors to be free from defects and will repair any such defects, however a damaged suppressor cannot simply be replaced with a new one if it cannot be repaired, an additional $200 transfer tax is required, and we will not be responsible for payment of this tax. The good news is, it goes directly back to you, not through a class dealer and no photos or fingerprints or LEO signature is required.
