KAK Industry Plan B 4-prong flash hider with 1/2x28 threading for .223 and 9mm rifles. Features tapered design for repeatable lockup and proper suppressor sealing. Nitride finished steel.
The Plan B flash hider from KAK Industry represents a thoughtful approach to muzzle device design. This four-prong configuration effectively reduces muzzle flash while maintaining a clean sight picture—a practical consideration for shooters in low-light conditions or those running optics.
What sets the Plan B apart is its engineering philosophy. The device features a tapered design followed by threads, which ensures repeatable lockup and a proper seal between the muzzle device and suppressor adapter. This precision fit is essential for suppressor performance and reliability.
For proper installation, use Rocksett thread-locking compound and apply 20-25 foot-pounds of torque. This ensures a secure, repeatable fit that will maintain zero across multiple installations and removals.
If you plan to use this flash hider with a suppressor, verify that your suppressor manufacturer approves Plan B muzzle devices. Some manufacturers will not honor warranty claims if non-approved muzzle devices are used with their suppressors.
