FAQs

How do I purchase a Liberty Suppressor? — The steps to owning one of our suppressors are simple. Here’s a basic rundown:

1. Locate a Class III dealer in your state to handle your transfer.
2. Place your order through Liberty Suppressors or your Class III Dealer.
3. Pick up your prefilled ATF Form 4 packet, from your dealer.
4. Complete your ATF Form 4 packet, which will require:
   1. $200 check payable to the ATF for your Transfer Tax Stamps
   2. Attach a passport portrait to the form. 
5. Mail your Form 4 packet to the ATF. Allow a minimum of one month (four to six months on average) for processing with the ATF. Once your Form 4 is approved, we will send it back to your dealer and then you can go pick up your Libery suppressor or silencer kit!

That’s it! Your suppressor is now yours to enjoy for a lifetime.

What is “at the ear” measurement? — The “At the Ear” or ATE measurement is the amount of pressure exerted on your ear drums by the sound waves produced by a gunshot. This is generally accepted as being the loudest and most important sonic parameter to consider when determining how effective a suppressor will be in protecting your hearing.

Why is ATE measurement important? — The ATE measurement not only takes into account the sound pressure level (SPL) reduction of the suppressor, but also takes into account the noise attenuation provided by ear protection. This is important because most shooters wear some form of ear protection while shooting.

What are some examples of ATE measurement for a rifle with different adapters? — For an AR15 with 55gr ball ammo rifle, the ATE measurements were found to be the following.

• Goliath 136.2 dB Average
• Sovereign With Direct Thread Adapter 133.2 dB Average
• Sovereign With Flash Hider Mount 134.1 dB Average
• Mystic X With a Standard FBA 138.8 dB Average
• Mystic X With Lopro FBA 138.9 dB Average

What is tone in regards to firearm silencers and suppressors? — The tone of a silencer is subjective to the individual and is more important than absolute decibel levels in the real world. The dB meter is great for scientifically determining that a certain design is safe for use, but in the end, the person designing the silencer needs to make sure the tone generated by the can will be pleasant to the ear as well as the meter. 

What makes Libery Suppressors stand out when it comes to tone? — There are many world-class 22LR silencers on the market today that measure less than 120 dB on a sound pressure level meter, but only one maker chooses to also apply the metric of tone when making silencers — and that maker is Libery Suppressors. 

How can I test the difference between Liberty and other firearm suppressors? To compare, get a Liberty Suppressor and a few silencers in the caliber you are looking for. Listen to them go off side by side on similar weapons, if possible. We feel that tonal differences make the silencer or break it for people, so try them out for yourself and you too will see how great Liberty Suppressors are!
