An Inside Look at How Suppressors Work

silencer design

Typically suppressors are optimized for a range of similar calibers. This is partly because they have to be engineered to allow passage of a given size bullet but also to contain the pressures of various rounds that use that bullet size. It is only reasonable then that people would want to see if smaller caliber rounds can also be adequately suppressed in a silencer designed for a bigger caliber. Firearms affected by this tax were machine guns, short-barreled rifles (SBR), short-barreled shotguns (SBS), and of course, suppressors.

Baffle Cover & Baffle

This was mainly to avoid wait times from local law enforcement, obtaining fingerprints, photos and in some extreme cases, chief local law enforcement figures would flat out refuse to sign any NFA paperwork. Much of this is no longer an issue due to an ATF Ruling a few years ago that stated the CLEO only needed to be notified of silencer purchases. Whether you consider them to be varmints or predators, coyotes are some of the most intelligent and cagey animals to hunt. They recognize gunshots for what they are and even the youngest or most naïve of these creatures will keep a smart distance in spite of your best predator calls once they hear one. A few states used to have some restrictions on hunting with a suppressor.

Using An Extra Long Bullet Path Drill Bit For Long Suppressors

Getting factory installed flash hiders and muzzle brakes off can be a pain in the butt without the right tools. I highly recommend you put a little anti-seize compound on the barrel, tube and end cap threads to make removal and disassembly easier. You can make a suppressor quieter by putting a few drops of water or oil into the suppressor and it'll really reduce first round pop. First round pop is caused by the burning of cold dense air inside the suppressor--after the first shot the suppressor is filled with burned gasses that cannot burn when the next shot is fired. The downside is the liquid will mix with powder residue and stick to the suppressor interior and hasten the need for cleaning. Be sure and check the security of the suppressor for tightness with a gloved hand between shooting breaks.

BENEFITS OF HUNTING SUPPRESSED

The most obvious benefit of hunting suppressed is safety, particularly when it comes to protecting your hearing. Noise-induced hearing loss is the most common affliction for hunters. A lot of this comes from hunters forgoing hearing protection so that they can hear their surroundings. You can generally use them with any caliber smaller than what they’re rated for.

Suppressor Design And Construction

Drilling the bullet path the full length of the suppressor baffle. Start the bullet path hole with a normal length drill bit for more precision then switch to a long bit when needed. Insert the completed baffle into the baffle cover tube and seal.

For a hard-use 5.56 SBR, the SureFire Socom556-RC3 is tough to beat. One of the most important things to remember when shopping for an SBR suppressor is barrel length restrictions; you need a silencer that will handle the pressure of your short-barreled build. You can make it short and light to minimize the size of your pistol or go longer for more sound suppression. It has 10 baffles, so you can dial in the perfect configuration for your unique scenario. The JK Armament CCX is the smallest 9mm pistol suppressor ever made.

This can cause them to function somewhat like a muzzle booster and thus increase the felt recoil. The weight of the silencer and the location of that additional weight at the muzzle reduces recoil through the basic mass as well as muzzle flip because of the location of this mass. To prepare for tapping the barrel thread I drilled the thread end of the baffle. The depth of this hole isn't critical because it will lead into the large blast baffle but it needs to be deep enough to allow the suppressor to screw onto all the thread offered by your rifle barrel. Longer baffles will need to be supported on the lathe by a steady rest (shown holding the baffle at near end).

To install on your gun, simply press the mount down over the muzzle (past the locking lugs) and a 30-degree twist will lock it in place. The Omega 36M uses Silencerco’s “Charlie” pattern endcaps and accessories. The small endcaps thread into the front of the suppressor and can be tightened or removed with included tools. Endcaps are available with several exit diameters, but the can comes with the standard .36-caliber cap. If you’re going the 3D printing route, now is the time to download the suppressor files, input them into the printer, and let it work some magic.

Additionally, the monocore design is easy to clean and maintain. Enhance your shooting precision with our 62 MOA Targets, perfect for rifles and handguns. Crafted in collaboration with Storm Tactical for accuracy and versatility. Alternately, the tube can be drilled at spots along its length where the flanges of the baffles would rest, the baffles inserted, and each hole weld-filled with the baffles in place.

These cartridges use very heavy bullets to make up for the energy lost by keeping the bullet subsonic. A good example of this is the .300 Whisper cartridge, which is formed from a necked-up .221 Remington Fireball cartridge case. The subsonic .300 Whisper fires up to a 250 grains (16 g), .30 caliber bullet at about 980 feet per second (300 m/s), generating about 533 foot-pounds force (723 J) of energy at the muzzle. Taking advantage of either property requires that the silencer be designed within the specification of the muzzle blast in mind.

Just like buying a suppressor, you have to get a stamp for each and every suppressor you build yourself. Uncle Sam still wants his money, and if you don’t want to be a felon, you’d better give it to him. As we stated in the warning at the very top of this page, you should not start building your homemade suppressor until you’ve paid your tax and received an approved Form 1 back from the ATF. To be extra safe, we recommend that you not even purchase the parts or kit for making one until you have the necessary government approval. Better safe than sorry because penalties for possession of a silencer, including DIY ones, are steep if you don’t have ATF approval and that $200 tax stamp.

Because sound travels through air, anything that impacts the density of the air also impacts the loudness of a given sound. A gunshot fired on a hot, humid day will measure differently than a gunshot on a cold, dry night. While it might seem desirable to test under extremely controlled conditions, this doesn’t allow for an understanding of how suppressors perform outside the lab. It’s DSX-D and PRS line of suppressors have an integrated M baffle in the entrance chamber that significantly reduces or negates entirely all first round pop.

The trapped gas exits the suppressor over a longer period of time and at a greatly reduced speed, producing less noise signature. There are typically at least four and up to perhaps fifteen chambers in a suppressor, depending on the intended use and design details. Often, a single, larger expansion chamber is located at the muzzle end of a can-type silencer, which allows the propellant gas to expand considerably and slow down before it encounters the baffles or wipes.

Lowe's and Home Depot sell rubber washers in a variety of sizes. A suppressor cover or wrap can also reduce noise from suppressor vibration. Note the large square blast baffle at the bottom and the heart shaped gas chambers. This suppressor worked out very well and is quieter than a commercial .22 suppressor I purchased later.

Some highly advanced suppressors include a clever piston system to help control the flow of gas. Once you’ve made the “guts” of the silencer, then it is time to add end caps. These close off the tube and allow for it to be threaded onto your gun on one end, with an opening for the bullet to escape on the other.

This can result in a quieter suppressor, a lighter suppressor, and/or a suppressor that’s more suitable for multi-caliber use since it can more easily be cleaned. Additionally, some firearms are more accurate with a good suppressor fitted. It may seem illogical or implausible, but ask anyone who has shot a lot of firearms suppressed and unsuppressed and they’ll likely tell you that some guns, with some loads, are much more accurate when using a suppressor. This may have to do with barrel harmonics, the reduction/dispersion/slowing of explosive gas on the bullet as it exits the muzzle, or both. The stacked baffles take a little more precision, supplies, and labor.
