Are Suppressors Legal in Iowa?
Yes. Iowa legalized suppressor ownership in 2016, and suppressors are legal for hunting in Iowa as well. You still have to follow federal rules for buying one, and you should check the Iowa DNR hunting regulations for the season and method you plan to hunt with.
To buy a suppressor from a licensed dealer you must be at least 21 years old, legally allowed to own firearms, and a resident of a state where suppressors are legal.
What Changed in 2026: The $0 Tax Stamp
For almost 90 years, buying a suppressor meant paying a $200 federal tax stamp on top of the price of the can. As of January 1, 2026, that tax is $0. It was eliminated by the federal budget bill signed in July 2025, and it applies to suppressors, short-barreled rifles and shotguns, and other NFA items.
What did not go away: the federal paperwork. You still submit an ATF Form 4, pass a background check, and wait for approval before you take your suppressor home. The difference is that you no longer pay $200 per item, so a suppressor for your deer rifle and another for your 9mm now costs only the price of the suppressors themselves.
How to Buy a Suppressor at Loftus Firearms, Step by Step
1. Pick your suppressor
Choose a suppressor rated for the calibers you shoot (see “How to Choose a Suppressor” below). Browse our suppressor selection online, or call us at 319-529-9838 and we’ll help you match a can to your firearms.
2. Decide: individual or trust
You can register a suppressor in your own name or to a gun trust.
- Individual: the simplest option. Only you may possess the suppressor.
- Trust: lets you name other people, such as a spouse or family members, who may also possess and use it. Everyone listed as a “responsible person” completes their own paperwork and fingerprints.
3. Complete your paperwork and fingerprints
We’ll help you submit your ATF eForm 4, which includes your fingerprints and a photo. You’ll need a free ATF eForms account. Your application is submitted electronically, and there is no tax payment step in 2026.
4. Wait for approval
The ATF reviews your application and runs a background check. Approval times vary with the number of applications the ATF is handling, and demand has been high since the tax was removed. We’ll contact you as soon as your approval comes through.
5. Pick up your suppressor
Once approved, you complete a standard Form 4473 and background check at pickup, just like buying any other firearm, and your suppressor goes home with you. Keep a copy of your approved Form 4 with your records.

The 2026 Court Ruling on Suppressor Registration
In August 2026, a federal court in Texas ruled in Silencer Shop Foundation v. ATF that the federal registration and approval requirements for suppressors can no longer be enforced against the people and businesses covered by that case, because the tax they were built on is now $0. The ruling does not apply to everyone automatically, and the federal government has until early October 2026 to appeal or ask for a stay.
Because this area of law is changing quickly, please contact us for the current process before you order. We will always walk you through the options that are available and legally sound at the time of your purchase. This guide is general information, not legal advice.
How to Choose a Suppressor
Caliber rating
A suppressor can be used with any caliber up to the maximum it is rated for. That’s why many buyers start with a .30 caliber rifle suppressor: it works on .308 Win, 6.5 Creedmoor, .300 Blackout and, with the right mount, 5.56. A can sized exactly for your caliber (for example a 5.56 or 9mm model) will usually be lighter, smaller and a bit quieter on that caliber. Rimfire suppressors are built for .22 LR and similar rounds and are some of the quietest and most affordable suppressors you can own.
Mounting system
- Direct thread: screws straight onto your threaded barrel. Simple, light and affordable.
- Quick-detach (QD): attaches to a muzzle brake or flash hider on each rifle, so you can move one suppressor between guns in seconds.
- HUB mount (1.375×24): an industry-standard interface used by many brands that lets you swap direct-thread and QD mounts on the same suppressor.
Check your barrel’s thread pitch before you buy. 1/2×28 is common on 5.56/.223 rifles and 9mm pistols, and 5/8×24 is common on .308 and other .30 caliber rifles.
Materials and weight
- Titanium: the lightest option, popular for hunting rifles you carry all day.
- Stainless steel and Inconel: heavier but very durable, ideal for short barrels and high round counts.
- Aluminum: light and common on pistol and rimfire suppressors.
Pistol suppressors
Most 9mm and .45 ACP pistol suppressors need a booster (piston) so the pistol cycles reliably with the added weight at the muzzle, plus a threaded barrel. Many pistol cans can also be used on pistol-caliber carbines.
Hunting in Iowa
For Iowa deer, predator and varmint hunting, a lightweight .30 caliber or 6.5mm-rated suppressor on a bolt-action rifle or straight-wall cartridge rifle is a popular setup. A suppressor reduces recoil and muzzle blast, protects your hearing without earmuffs, and makes follow-up shots easier. Always confirm current Iowa DNR rules for the season you are hunting.
Suppressor FAQ
How much does a suppressor cost in 2026?
Only the price of the suppressor itself. The $200 federal tax stamp is now $0, so there is no extra federal tax to pay.
Do I still need a Form 4?
For the standard purchase process, yes. You still submit an ATF Form 4 with fingerprints and wait for approval before pickup. See the section on the 2026 court ruling above for recent changes, and contact us for the current process.
Can I hunt with a suppressor in Iowa?
Yes. Suppressors are legal for hunting in Iowa. Check Iowa DNR regulations for the specific season and weapon type.
Does a suppressor make a gun silent?
No. A suppressor reduces the sound of a gunshot to a level that is much safer for your hearing, but it is still loud. Hearing protection is still a good idea at the range, especially indoors.
Can I use one suppressor on multiple guns?
Yes, as long as every gun is at or below the suppressor’s caliber rating and has a compatible mount or thread pitch. Quick-detach and HUB mounts make switching between guns easy.
Do I need a threaded barrel?
Yes, your firearm needs a threaded barrel or a muzzle device the suppressor can attach to. Many rifles and pistols ship with threaded barrels, and aftermarket threaded barrels are available for most popular handguns.
