The BANISH Speed K direct thread suppressor for .223 Rem/5.56mm is built for shooters who need serious sound reduction without compromise. Constructed entirely from Inconel—a material chosen for its durability and heat management—this 4-inch suppressor delivers 20.9 dB of sound reduction while maintaining reliable function across both semi-auto and full-auto platforms. Developed in partnership with Federal Ammunition and law enforcement, the Speed K is engineered for tactical applications where dependability and performance matter.
The suppressor's design emphasizes practical performance in real-world conditions. Its clipped-wall baffles and finned blast chamber work together to maximize sound attenuation, while controlled flow technology and a vented 4th baffle keep gas blowback to just 5.8% above unsuppressed levels—meaning your rifle cycles reliably without modification. At only 14.1 ounces and 4 inches long, the Speed K won't bulk up your rifle or slow your movements in tight spaces. It comes with an industry standard hub mount (1/2x28 thread pitch) that allows you to run it as a direct-thread can or adapt it to a quick-detach system with optional muzzle brakes.
Durability is where the Speed K stands apart. It passed seven rounds of SOCOM testing—each round driving 1,440 rounds downrange in rapid succession. Most suppressors don't survive even one. That level of proven reliability, combined with a lifetime warranty, makes this a suppressor you can trust when it counts. Whether you're running precision drills at the range, hunting with a modern rifle, or relying on a 5.56 platform in demanding conditions, the Speed K delivers the sound reduction and durability professionals choose.

The Speed K is designed for .223 Rem and 5.56mm platforms. The 1/2x28 direct-thread mount fits the standard muzzle thread on modern .223/5.56 rifles. It is rated for both semi-auto and full-auto fire.
Yes. The suppressor comes with a direct-thread hub mount, but it features an industry standard hub that allows you to attach optional muzzle brake devices for quick-detach mounting if you prefer that flexibility.
The Speed K delivers 20.9 dB of sound reduction. While no suppressor makes a rifle hearing-safe in isolation, this level of attenuation significantly reduces report in tactical, hunting, and range applications.
No. The Speed K's controlled flow design and vented 4th baffle limit gas blowback to only 5.8% above unsuppressed levels, meaning your rifle will function reliably without any modifications. It's rated for full-auto use, so semi-auto rifles cycle normally.
