Plan B Muzzle Device Ecosystem

The included Plan B Trident Flash Hider opens access to the Plan B suppressor mounting ecosystem. This modular interface allows you to add compatible suppressors without replacing the flash hider, creating a streamlined suppressor-ready platform. The three-prong design manages flash signature while maintaining the ability to swap between flash hider and suppressor configurations as your needs evolve.

Precision Barrel and Gas System Tuning

The 1:8 twist rate with rifle-length gas system delivers reliable cycling across standard and heavier 6.5 Creedmoor loads. The adjustable gas block lets you fine-tune performance based on your specific ammunition, reducing felt recoil and brass ejection patterns while maintaining reliability. This tuning capability is essential for precision shooting where consistency matters.

Free-Float Handguard Advantage

The 17-inch free-float M-Lok handguard isolates the barrel from contact with the upper receiver, eliminating a major source of accuracy variation. M-Lok attachment points give you unlimited mounting options for optics, lights, and accessories without compromising the barrel's harmonic consistency.
