Operative B 17 HMR Nighthunter Rifle from Thompson Machine

Thompson Machine

Thompson Machine is now offering an integrally suppressed 17 HMR rifle based on the Savage 93R. The Savage 93R is a bolt action rifle that comes in a variety of styles. One such variant comes with a threaded barrel. However, Thompson Machine decided to go with integral suppression for a lower profile and shorter overall appearance.

This rifle is part of the company’s Nighthunter line of rifles. It partially derives its name from the all black appearance of the gun.

Although the barrel looks like a standard bull barrel, it is actually an integral suppressor. The tube is made of titanium and has a black Cerakote finish. Inside, the baffle is also made of titanium. You can see the rifle in action in the video below.

One of the things that the video shows is how the crack of the supersonic bullet can change based on external factors. For example, the crack seems nearly simultaneous to the firing on a short range. However, on a 600 yard range (presumably more wide open with a berm at about the 600 yard mark) there is a perceptible difference from the sound of the shot being fired and the bullet’s supersonic crack.

Thompson Machine makes several other integrally suppressed rimfire rifles including an Operative B based on the CZ455 and several based on the Ruger 10/22 platform.

    inb4 suppressing 17 HMR is useless because of sonic crack.

    • Christian Hedegaard-Schou

      Still much quieter than unsuppressed, making it hearing safe.

        I know, thus the “inb4”.

    I wish this guy would still allow people to download the measurements for his American 180 build.
