Silent Steel USA Suppressors: A Technology Walkthrough

Most suppressors work the same basic way: gas enters a stack of baffles, expands, and exits the muzzle slower and quieter. Silent Steel USA took a different approach with a baffle-less design that sends gas forward and comes apart without tools. Guns & Gear's Ryan Gresham sat down with the company's Justin Sheehan, then Chris Cerino took it to the range.

What Is It?

Silent Steel USA is a veteran-owned company that makes suppressors in Michigan. It is the American arm of a Finnish suppressor maker, and the company describes its products as “Finnish Heritage. American Grit.”

What sets the design apart is that there are no baffles. As Justin explained in the studio, a turbine causes the gases to swirl as they enter the tube. The swirling gas hits a filter element, and the result exits the front of the suppressor instead of coming back through the action toward the shooter. Silent Steel calls its patented system FLOW-IQ.

You can see how it works because the suppressor comes apart. Unscrew the end cap, pull the core, and the turbine and filter are right there in your hand.

Cleaning It

Most traditional suppressors can’t be fully disassembled. You can’t always reach the areas where carbon builds up, so you either live with a dirty can or send it back to the manufacturer. Silent Steel’s removable airflow system comes apart without tools, and the company says that allows a thorough cleaning.

In the segment, the cleaning method is simple: pull the core, scrub it with a stiff-bristled brush in hot, soapy water, or run it through an ultrasonic cleaner if you have one. For anyone who shoots a suppressor hard and often, that is a real advantage.

The Product Line

Silent Steel offers three sizes: the Micro Streamer at 4.25 inches, the Compact Streamer at 5.9 inches and the full-length Streamer at 7.6 inches. Performance goes up with size. As Justin put it, physics are physics: more volume means more capability.

He said the compact is the most popular, a good balance of size and performance for most uses. The full-length Streamer is the pick when quiet matters most, and the micro is the most portable, adding minimal length to the host firearm.

On the Range

Chris Cerino ran the compact and the micro on a .308 AR. The compact left him with what he called a “kind of awesome” experience: quiet, with the gases going forward instead of back at him. The micro was louder, as expected with less internal volume, but still effective.

Heat was the other thing he noticed. He said the suppressor was still touchable bare-handed after 30 rounds through the 9mm Streamer in an earlier test. After three shots through the micro on the .308, he felt some heat through a glove, but nothing alarming.

Final Thoughts

Silent Steel USA is building a suppressor that works differently from the baffle stack most shooters know. The forward-flowing gas, the tool-free disassembly and the easy cleaning make it worth a look for anyone who shoots a suppressor often. Learn more at Silent Steel USA.
