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 1440 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.
