Description

Designed for law enforcement and military applications in mind, the Speed K 5.56-caliber suppressor is extremely durable. Made from 100% Inconel and full-auto rated. 

Some tactical situations call for close-quarters action in highly stressful environments. The last thing you need is for your rifle to blow out your hearing. That is where the BANISH® Speed K comes in. Created in partnership with Federal Ammunition and law enforcement, it is a 5.56 caliber suppressor designed with LEOs and military uses in mind. 

With clipped-wall baffles and a finned blast chamber, the Speed K ensures maximum sound reduction while maintaining optimal performance. Controlled flow technology and a vented 4th baffle minimizes gas blowback for better shooting. This means only a 5.8% increase in blowback compared to unsuppressed shooting, enabling rifles to function smoothly without additional modification. 

The Speed K is constructed using 100% Inconel for durability and lower heat retention. Passing seven rounds of SOCOM testing, the Speed K is extremely durable and won’t fail when it matters most. One round of SOCOM testing puts 1,440 rounds through the suppressor in a short period. Many suppressors don’t pass one round of SOCOM testing, let alone seven. 

At 4 inches in length, the Speed K is the perfect design for quick and precise movements in tight spaces. The suppressor comes with a direct-thread industry standard hub mount. Muzzle brake devices are also available for purchase. The 1.375×24 hub mount allows purchasers to attach a separate quick-detach mount. Trust what the pros trust and equip your rifles with the BANISH Speed K.

What People Are Saying

Home Defense Suppressor

The Speed K is the way for keeping home defense and close quarter protection from creating a weapon too long to control inside the home for clearing the house or other buildings. I am a big fan of the materials used in the construction of this silencer and I won’t be worried about overheating this gun accessory. I believe this to be everything I wanted in my personal defense weapon accessory.

Makes shooting fun

I used the Speed K on a “fun gun” with a 6.5 inch barrel. The speed K *drastically* reduced its sound signature, and there was no noticeable gas blowback at all. On my serious weapon, with an 11.5 inch barrel, sound signature obviously better and what’s more amazing is the recoil was drastically reduced, no gas in my face. I love my Banish 30 and now I love my Speed K. I know I’ll be back for another product.

Extremely quiet

Received my Speed K and I love it. The size is just right and the noise reduction is hearing safe. Easy to get on and off. Another great product from BANISH Suppressors.
