Answering your questions about Suppressor Maintenance and Longevity
November 18, 2025
A suppressor represents a significant investment in your shooting activities and hearing protection. It makes sense, then, to do whatever you can to protect that investment and keep your suppressor operating at peak performance. Let’s cover all of your questions about suppressor maintenance and keeping your suppressor running right for the long haul. Let’s start by answering some questions on how to maximize the overall life of your suppressor.

How carbon build-up affects suppressors?
Carbon buildup forms inside suppressors due to incomplete combustion of gunpowder residue. This buildup can erode internal components like baffles made from various alloys such as Inconel, stainless steel, or titanium. The importance of regular cleaning cannot be overlooked. There are different cleaning methods for user-serviceable versus fully-welded suppressors. Plus, there are factors like ammunition type, firing frequency, and firearm caliber that influence the frequency of cleaning and overall suppressor wear.
You should plan to routinely clean your suppressor following the guidelines laid out in your owner's manual. Suppressor maintenance will make your can last a lifetime.
Carbon is one of those elements that is everywhere. If you know anything about the makeup of gunpowder, then the fact that you’re going to have carbon build up should come as no surprise at all.
Where carbon comes from in your suppressor is from incomplete combustion of the gunpowder from a gunshot. That material will go into your suppressor and appears as black soot, like in a chimney of a fireplace. Shooting over time increases the carbon buildup in your suppressor. This can lead to the erosion of the baffles, whether that's Inconel, stainless steel, or even titanium. A way to prevent this is obviously cleaning that suppressor over a scheduled period of time.
That answer depends on which type of suppressor you’re talking about. There are two basic types of suppressors - user serviceable and fully welded.
User-serviceable suppressors can be disassembled, and the baffles are able to come out. You are then able to clean those baffles independently from the main tube. Make sure you follow the owner’s manuals about taking the suppressor apart and reinstalling the pieces after cleaning. If you're at all unsure, check your owner's manual or contact us for help.
A fully welded suppressor cannot be disassembled for service. These are often the suppressors made using additive manufacturing processes, like 3D printing. Obviously, those baffles do not come out. With these types of suppressors, the best cleaning option is submerging the entire suppressor in a suppressor cleaning solution. Just be aware that you use something that's not going to tarnish any Cerakote or any finish on your suppressor. Click below to read about the best way to clean a welded suppressor.
How dirty your suppressor gets depends on how how and how much you shoot. From a round count perspective, it obviously depends on what you're shooting but simply shooting a high-pressure .30 caliber cartridge, like .308 Win.. You can get anywhere from 300 to 500 rounds before you actually notice a weight and performance difference in your suppressor as well as a good sound reduction decrease in your suppressor.
The round count between cleaning also depends on the type of ammo that you're using. You will have to determine that for yourself. Whether you're shooting premium high-quality ammunition, bulk ammunition, or even subsonic ammo. It is all going to lead to the different times that you must clean your suppressor. However, you are going to notice a significant weight difference and sound difference when the carbon is building up.
What suppressor alloy fits my firearm application?
Suppressors are made from several materials - Aluminum, Stainless steel, Inconel, and titanium. Knowing what works best for each allow will make cleaning them easier. Photo by Ryan Grant.
There are three main materials used in suppressor construction: Inconel, stainless steel, and titanium. Stainless steel and Inconel are going to be really for those high firing schedules, fast fire rates, and intense use. Titanium can become kind of brittle if you use one for full-auto or intesense firing schedules and really let it overheat. Most hunting suppressors being lightweight are going to be made from titanium. Most low back pressure 5.56 suppressorsyou're going to see either in stainless steel, or Inconel, or a combination of both.
And yes, aluminum is used in select suppressors, often in rimfire and pistol-caliber cans. For these applications, it hold up quite well. Aluminum actually disperses heat quite well, but being a softer material, it is not often used for high fire rates, unless it is rimfire.
Barrel length importance
Making sure that your suppressor works with the barrel lengths that you have for your firearms helps with the longevity of the suppressor and especially that first baffle, which is considered a blast baffle in most suppressors. With welded suppressors, this is something that you can't take out to check. It can lead to damage and then having to return it back for warranty. The best resource here is the, you guessed it, owner's manual.
How do I prevent baffle strikes?
Misaligned suppressors can cause baffle strikes where the bullet contacts internal parts, potentially leading to irreversible damage. The best defense here is an alignment rods. It can help ensure that your baffles are lined up correctly. Using alignment rods to check concentricity ensures that bullets pass cleanly through the barrel and suppressor.
This is especially important for suppressors with quick-detach (QD) systems or muzzle devices, where slight misalignments can accumulate through repeated attachment cycles. Proper alignment not only preserves suppressor life but also ensures firearm accuracy and safety.
Most manufacturers offer lifetime warranties that cover defects and irregular wear, providing peace of mind for suppressor owners. Promptly contacting manufacturers for repairs under warranty can save money and extend the suppressor’s functional life. Understanding warranty terms before purchase can influence buying decisions and long-term ownership satisfaction.
Most manufacturers’ warranty processes allow you to be able to send the suppressor to them, they're going to be able to fix it and send it right back to you. You don't need to worry about issues with the ATF here.
