KAK Plan B 4-Prong Flash Hider 1/2x28

KAK Plan B 4-Prong Flash Hider

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.

Design and Function

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.

Specifications

• Thread Pitch: 1/2x28 (standard for .223 Remington and 9mm rifles)
• Bore Diameter: .375" (.223-9mm compatible)
• Finish: Nitride (durable, corrosion-resistant)
• Color: Black
• Compatibility: Plan B suppressor hubs

Installation

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.

Important Compatibility Note

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.
