In 1902 Hiram Maxim invented the muffler on your car AND the muffler on your gun, aka a Suppressor. The design to quiet your car and your gun are quite similar. They both give the hot gases from combustion space to expand and cool. The space to cool, the quieter they are. This expansion in space & cooling of the gases significantly reduces the audible sound. While advancements in materials, welding, and baffle design have evolved, the principles of sound reduction remain unchanged. Until we can defy the laws of physics, we’ll continue to make incremental improvements in sound suppression by using space age materials, advanced coatings, and efficient baffle design. We also find the fight to make Suppressors more accessible, without the wait times and taxes.


Find which Suppressor meets your needs. An easy path is to determine what caliber you’ll be shooting, and then determine what you value most. If “Light it right”, pick the EVO Ti™ Series. If you shoot a lot and train hard, the DURA HD™ Series will be the best choice. A staff member at a Class III dealer should also help you select a great Suppressor. Decide how you will register your suppressor- purchasing individually or through an NFA Trust. Find a dealer that has the items you want in stock or can readily get them in a timely manner. The folks at Silencer Shop have the products, the process, and the experience to get you shooting quietly, quickly, and easily. 


Make your purchase. Have your dealer submit your form 4 application to the ATF with the appropriate documentation and $200 tax for each item.


Pick up your suppressor after approval. You can pick you item up directly from the dealer either at their place of business or eligible qualifying event  like a gun show. Your dealer can also ship the suppressor directly to you. The shipping option requires an additional step but only adds approximately 14 days to your wait time. Contact your dealer or Silencer Shop for details.

Fill out the ATF Form 5330.20 (Certification of Compliance). This form does not have to be in duplicate.

Place both completed copies of Form 4, the two copies of FBI fingerprint cards, and the completed Certification of Compliance form in an envelope, along with a check or money order (payable to Bureau of Alcohol, Tobacco, Firearms, and Explosives) for $200 and mail to the address listed on Form 4.


Proper sound suppression requires that all powder is burned in the chamber & barrel. Short barrels create a possibility that unburned powder can be deposited in the suppressor, creating a hazard with a potential for catastrophic consequences. Full powder burn is required for safety and best sound suppression performance, for all suppressors.
