New BANISH 556 Hard‑Use Rifle Suppressor
Suppressor development continues to accelerate heading into 2026, and BANISH Suppressors has added a new dedicated 5.56 offering to its lineup with the release of the BANISH 556. Designed specifically for modern AR‑pattern rifles, the new suppressor is intended for shooters running full‑auto, semi‑auto, carbines, and SBRs who demand durability, reduced back pressure, and consistent performance.
The BANISH 556 is engineered around a controlled‑flow gas system designed to manage pressure more effectively than traditional baffle stacks. By slowing and redirecting gas internally, the design reduces recoil impulse and limits excess back pressure to the action, improving shooter comfort and reliability during extended firing sessions. The suppressor is rated for hard use and carries no barrel length restrictions, making it suitable for a wide range of rifle configurations.
The suppressor is produced with metal additive manufacturing and conventional machining techniques. A stainless‑steel blast chamber is paired with an Inconel suppressor body, allowing the design to maximize internal volume and baffle count while maintaining structural strength. A helical vent pattern further aids in gas management, contributing to both flash and sound reduction during sustained fire.
Mounting flexibility is addressed through the use of an industry‑standard HUB interface, allowing compatibility with a variety of mounting systems. The suppressor ships with a 1/2×28 direct‑thread adapter and is compatible with other HUB‑based solutions as needed. The BANISH 556 is offered in black or flat dark earth Cerakote finishes to match common duty and sporting rifle setups.
"Everything we have learned about materials, manufacturing, and the dynamic movement of pressurized gas through suppressors has been leveraged in making the BANISH 556," said Brandon Maddox, BANISH Suppressors Founder and CEO. "I challenged the design team to create a new 5.56 suppressor that offers best-in-class noise and flash reduction, low back pressure, durability for hard use – including a full-auto rating – and overall dimensions that keep it portable and suitable for use by military and law enforcement professionals, as well as armed citizens. The result is the BANISH 556, and a whole new level of performance from tactical suppressors."

One thing I greatly appreciate, and that I think all customers should demand, is the sound reduction data and how it was measured. This suppressor gets a 132.4dB average on a 16” AR-15, and 137dB average on a 10.5” AR-15.

I'm confused as to how they word the decibel rating. Does it mean that the suppressor reduces the sound of the gunshot down TO 132.4db, or it reduces the sound BY 132.4db?
So If the average rifle gunshot is 155dB, does this suppressor make the sound volume 132.4dB, or 22.6 dB?
Unless you are spitballing out of a paper straw, it will never be 22.6dB for a 556 round.
