Whistle Tip - Blast Mitigation Tip & Thread Protector for Cherry Bomb The Whistle Tip is a precision blast mitigation device from Q LLC that redirects sound and concussive energy downrange and away from the shooter and nearby shooters, improving comfort and reducing microconcussion on the firing line. Machined to Q's quality standards, the Whistle Tip doubles as a thread protector for the Cherry Bomb muzzle brake and uses a taper mount shoulder to ensure correct alignment with the Cherry Bomb when installed. Finished and fitted for repeatable service, it installs quickly with any 1inch wrench for fast, toolsimple fitment. Compatible specifically with Q's Cherry Bomb tapermount muzzle brake and intended to be used as both a BMD and a protective cap when the brake is removed.
