Steel, aluminum, and titanium
- Materials like steel, aluminum, and titanium are used in making silencers, and each has its pros and cons. Steel is the most robust and will typically be rated for full-auto use. But steel will be heavier and will add a lot of weight to the end of your firearm. This added weight could wear you out by the end of a range session or hunting trip.

Jan 12, 2021 · Aluminum is a very light-weight material that works great in rimfire suppressors. In fact, some of the highest performing and lightest weight .22 suppressors, like the SilencerCo Warlock II (only 3 ounces), are made from aluminum. Although it works great for .22 LR, it really isn't strong enough to handle pressures from higher-pressure calibers ...

Making a suppressor is both easy and difficult. It is easy, in that pretty much anything you put over the end of the muzzle will dampen noise. (Which can, in some instances and designs, be against the law without proper paperwork.) It is difficult in that what you use to dampen noise can degrade accuracy, cause difficulties aiming, and can be incon...
The baffle stack design entails a tube, and inside the tube the manufacturer places a stack of relatively cone-shaped baffles. Back in the early days, there were two versions, the “K” baffle and the “M” baffle. Today, we have more than two, they all work, and the details matter only to those who obsess over fractions of a dB in on-the-range testing...
A sealed unit will have, at the very least, the front and end caps welded to the tube. Generally speaking, more welding creates a more durable a suppressor. There are five levels.
Here, the front and rear caps are welded on and the baffles are simply pressed into the tube and trapped in place. While the baffles are tightly packed, they are not attached to the tube.
On these (usually older designs), the baffles are stacked outside of the tube, and the edges welded at two or three points on their perimeters, creating a rigid assembly. The welds are then filed/ground flush, and the baffle stack is pressed into the tube, where the caps then are welded on. Alternately, the tube can be drilled at spots along its le...
Here, the rim of each baffle is welded its full circumference to the next baffle in the stack. The assembly is then ground or lathe-turned to be round again, and then pressed into the tube, where it can be welded in place or the caps welded on, or both. Also, each can be welded in turn into the tube, but this is a lot more difficult.
This is the process used by Sig. They fabricate the baffles such that they have external, cylindrical skirts. The baffles are then fully welded into a stack, and the skirts form the tube that the baffle stack would otherwise be shoved into. This is a process that requires a great deal of precise equipment, but the end result is a suppressor with gr...
Here, instead of the baffle stack being composed of a series of cone-shaped parts, it starts as a solid cylinder of the baffle material. Then, through the magic of multi-axis CNC machining, the cylinder has gaps, holes, and baffles machined out of the bar stock of metal. This is then inserted into a tube. The big advantage here is that the monocore...
Which method a manufacturer uses depends in part on when they began making suppressors, how much they are willing to invest in capital equipment, and what the caliber and use demands. A maker that has been in business for a number of years, with familiar equipment capable of making solid, dependable old-style suppressors, may be reluctant (and unde...
The popularity of suppressors has caused a growth in the number of outlets where you can buy them. Gun shops that were “01 dealers” only had to add an SOT to their license wall, and then they could begin selling suppressors. As a measure of their popularity, you can now find suppressors in the Brownells catalog. Buying is easy. Frustrating because ...
Jul 9, 2016 · Aluminum: A lightweight metal that is easy to machine, aluminum is typically only used on rimfire builds or some pistol builds with caution. Stainless Steel: Strong but heavy, stainless steel can be used on almost any type of host. Because of the weight limitations, stainless steel builds on the end of long rifle barrels should be avoided.

Jan 31, 2024 · Rifle Suppressors: The most common type, designed for high-pressure cartridges, made from robust materials like stainless steel, titanium, or superalloys. They are often full-auto rated and can be attached via direct thread or quick detach (QD) systems.
Apr 2, 2024 · The short and sweet version is that a silencer (or suppressor) works by catching expanding gases in an expansion chamber. These gases are then cooled, and their escape from the muzzle is slowed by a series of baffles. This process causes recoil reduction and reduces both muzzle blast and muzzle flash, making the firearm much quieter.
Apr 6, 2022 · Suppressor materials vary from 7075 aluminum to titanium to 17-4 stainless steel to name brand superalloys like Inconel and Stellite. When engineering a silencer, the manufacturer will evaluate weight, cost, machinability, and durability so it can be used for generations.
