When a round fires, a column of gas leaves the muzzle at enormous pressure and temperature. That sudden expansion into open air is the blast you hear. A suppressor gives that gas somewhere to go first — a series of chambers and baffles where it can spread out, slow down, and cool before it ever reaches the air.
Lower the pressure spike, lower the noise. A good suppressor takes 20–35 dB off the muzzle blast. What it can't touch is the sonic crack of a supersonic bullet — that's why subsonic ammunition sounds dramatically quieter through the same can.
Pick a host, a suppressor, and your ammunition. The meter shows where the shot lands against the 140 dB line where hearing damage begins — and why subsonic ammo is the real unlock.
The One Big Beautiful Bill Act cut the federal transfer tax on suppressors from $200 to $0, effective January 1, 2026. For nearly a century that stamp was the single biggest hurdle to ownership. It's now zero.
What didn't change: suppressors are still NFA items. The registration, the Form 4, the background check, and the wait for approval all remain. The cost came down — the process stayed.
Five steps, start to finish. The same path whether you buy from us or anywhere else.
We connect you to licensed dealers; your payment runs through our partner GunTab, which holds the funds until the transfer clears. Piece & Quiet never takes possession of the suppressor or the money — every item moves dealer-to-dealer and transfers to you on your own Form 4.
Selling a suppressor you own works one of two ways, depending entirely on where your buyer lives. Each path runs start to finish below.
Federal law sets the floor; your state has the final say on possession. Civilian suppressor ownership is prohibited in eight states and the District of Columbia. A couple of states allow ownership but restrict hunting with one — always confirm your local statute.
