Description & specs

The BANISH® Speed K is a 5.56 caliber suppressor set to revolutionize the suppressor industry. With clipped-wall baffles and a finned blast chamber, the Speed K ensures maximum sound reduction while maintaining optimal performance. Featuring controlled flow technology and a vented 4th baffle, this duty suppressor minimizes gas blowback for a better shooting experience. The design allows for only a 5.8% increase in blowback from unsuppressed shooting, enabling rifles to function smoothly without additional modification.

Designed in partnership with Federal Ammunition and law enforcement professionals, the Speed K was built for those in uniform who demand excellence from their equipment. The silencer is constructed with 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 rounds!

At 4 inches in length, the Speed K is the perfect choice when maneuverability and speed are vital to a successful mission. The compact design allows for quick and precise movements in tight spaces. Creating a suppressor short in length was a primary focus when designing and building the Speed K, along with minimal blowback and extreme durability.

The BANISH Speed K 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.

If your mission is silence, trust what the pros trust and equip your rifles with the BANISH Speed K.

All silencers require the purchase of a $200 Federal Tax Stamp.

No, a silencer does not count as barrel length. A silencer will only count towards barrel length if it has been permanently pinned and welded on. There is not a good reason to attach a silencer permanently, since it reduces its usability and makes it harder to clean.

The only real reason to do so is to lengthen your gun’s barrel in order to avoid buying a SBR tax stamp. But usually, the cost to safely affix a silencer permanently is more than the cost of the stamp.

Absolutely. In fact, rifles are by far the most common type of firearm on which to mount a silencer. Like rifles, silencers are common among hunters. Your hunting rifle should definitely have a silencer, because first and foremost, they reduce noise pollution. Meaning you’re not going to scare off every critter in a 10 mile radius.

But silencers also reduce recoil, muzzle blast, and the risk of hearing damage. They also are known to increase accuracy, helping you make that once-in-a-lifetime shot. Some rifles can also be integrally suppressed to reduce noise even more. They also have important safety benefits, like allowing you to be more aware of your surroundings. Without having to wear hearing protection, you can listen for sounds of other predators or hunters.

No, .223/5.56 silencers are not illegal. You can very legally purchase and own a silencer in 42 of our 50 U.S. states. (If you are hoping to buy one in California, Illinois, New York, New Jersey, Massachusetts, Rhode Island, Delaware, Hawaii, or Washington D.C. you would be out of luck!)

If you are in the 42 states that have legalized silencers, you can trust that Silencer Central is there with you. We are licensed in all of those 42 states. Regulations are on a state-by-state basis, so take a look at our state-by-state guide on silencer ownership.

Don’t worry about traveling with your suppressor. Unlike other NFA items, you do not have to notify the ATF of your traveling or relocating plans.
