Welcome back to Silencer Saturday. This week we are taking a look at the new Angstadt Arms Prophet silencer. Luke C. got his hands on it at Trigger Con in a video you should watch here. This is a unique design that blends some features in new ways. Let’s dig into the design a little more.


Silencer Saturday @ TFB:


Disclaimer: Silencers are highly regulated in the United States. Be sure you know the laws before you get into the silencer game. The rules around what is or is not “permanently attached” to a barrel are another area where you can run into legal issues. Be sure you read the ATF’s guidance on that topic before you do anything that could get you in trouble.


Why Integral?


There are two main reasons to opt for an integral silencer over a traditional detachable model: Compactness/performance, and legal compliance reasons. Some legendary guns like the Welrod and MP-5SD were built around silencers and showed exceptional performance. Building the gun and silencer as part of a system also helps optimize suppression performance and ensure reliability.


The other main reason that people use integral silencers is legal compliance. In the United States, a rifle must have a 16-inch barrel. Any shorter and the gun must be registered as a short-barreled rifle, and be subject to the same legal framework as a silencer. However, a silencer permanently attached to the barrel counts towards that 16-inch requirement. The other approach is adding a silencer on the end of the 16-inch barrel (or 14.5-inch with a permanently attached muzzle device), which is longer and affects the balance more.


Angstadt Arms already produces integral silencer options. The Vanquish 22 suppressor is a unique design because it does not use baffles. It replaces the barrel of a 10/22 and has an inner barrel and outer sleeve. The series of ports along the barrel vent into the outer jacket where the gasses are able to expand and cool. This design runs the full length of the barrel.

What Is The Prophet?


Angstadt Arms has not posted any product photos of the Prophet yet, so we will be using screen grabs from Luke’s video at TriggerCon 2024. At first glance, it looks like a fairly standard integral suppressor. The outer sleeve contains baffles and sits over the barrel. On a cutaway view, the ported sections of the barrel line up with the baffles.


Because the barrel is all one piece, and the barrel remains on the gun, there are no legal issues with removing the can. There are still 16 inches of barrel even without the outer shell. This makes for easy cleaning and maintenance as well, which is not always the case with integral suppressors.

But here is the really interesting part: The Prophet is not just for use with this dedicated barrel. The back end of the silencer is threaded 1.375x24, so it can mount on any HUB-compatible mount. With the Prophet pulled off of the dedicated barrel, it can run on the HUB threaded mount system of your choice.


Another interesting feature is the bore diameter. The bore is large enough to accommodate the barrel when used in the integral configuration. When used as a standalone silencer, the Prophet has a .46-inch bore. That is a popular size because it allows almost all common calibers. In the video, classic options like .45-70 are mentioned, but a full compatibility list is not yet available. Some magnum calibers may not be on the final list, but we will hae to wait and see.


Note that the suppressor does not thread on at the muzzle, but threads on at the rear to a HUB fitting on the barrel.

Luke asked about full-auto use, and that may be possible in some situations but is not ideal for this suppressor. The Prohpet is made of Grade 5, 3D-printed titanium. That would mean a lot of sparking. Perhaps we will see other materials in the future that are more appropriate for rapid fire.


Angstadt’s Prophet has made an impact since it was unveiled. It won the Golder Triggr award at TriggerCon 2024 for Most Innovatice Silencer. In my opinion, that is well deserved. It combines the convenience of an integral can when used with the matched barrel with the flexibilty to be another multicaliber silencer in your arsenal. One suppressor can pull double duty on an AR, or on a big bore lever action.


Angstadt expects the MSRP for the Prophet silencer to be $795, and the barrel should be around $200. A $200 tax stamp for Uncle Sam is also required. Look for more details around January 2025, around the time of SHOT Show. We will be sure to keep an eye on the Prophet project as it progresses.
