SUPPRESSOR INTERFACE / MUZZLE BRAKE | WHISPER RAPID-THREAD | 5/8"x24

The 6.8 SPC/.30 caliber Rapid-Thread Muzzle Brake is a robust and efficient suppressor attachment for our Whisper suppressor. The hardened, Melonited steel construction in conjunction with the suppressor acts as the initial blast baffle and reduces internal suppressor wear. This collar-style brake slides over the barrel muzzle to further support the barrel threads during suppressor use and centers the suppressor, reducing the likelihood of baffle strikes. For optimal efficiency and maximum muzzle rise reduction, the Rapid-Thread Muzzle Brake is certainly one of the best products on the market with its suppressor detached. The brake comes complete with a shim set for proper timing to your rifle barrel threads and an O-ring for seamless use with Whisper suppressors. Additionally, if you have .740"-.775" diameter barrels measured ½" from the threads then this collar-style version will fit perfectly! If your barrel is larger than that range however, simply opt in for our flat back models available in different calibers.
