Yankee Hill Machine Flash Hider Phantom 5C2 Aggressive Parkerized

The Yankee Hill Machine Phantom 5C2 Aggressive Flash Hider is a parkerized muzzle device built for shooters who need serious flash reduction without sacrificing practical shootability. If you're running a .308 rifle and want to tame muzzle flash on the range or in the field—especially when shooting from prone—this 5-port design delivers the performance where it counts. The Phantom 5C2's port layout avoids facing downward, which means less dust signature and kickup when you're low to the ground, a real advantage in precision rifle work and tactical shooting.

Built by Yankee Hill Machine Co., a maker with a solid reputation for durable muzzle devices, the Phantom 5C2 combines aggressive flash reduction with a design philosophy that works for the shooter, not against him. The parkerized finish is corrosion-resistant and pairs well with mil-spec and combat-duty rifles. At 2.25 inches long with 5/8x24 thread pitch, it threads directly onto standard .308 rifles without adapters. Installation is straightforward—the included crush washer (with teeth for positive engagement) ensures a solid, repeatable fit.

Whether you're zeroing a new build, training at distance, or running suppressed guns where flash hiders are secondary to sound reduction, the Phantom 5C2 won't let you down. It's a no-frills, functional choice for riflemen who understand that flash management matters downrange and on the clock.

Frequently Asked Questions

Will the Phantom 5C2 fit my .308 rifle?

Yes, if your barrel has a 5/8x24 thread pitch. This is the standard thread for .308 rifles. The Phantom 5C2 threads directly onto compatible barrels; no adapters are needed. The included crush washer ensures a secure fit.

What is the crush washer and why does it have teeth?

The crush washer is a steel ring that goes between the flash hider and your barrel shoulder during installation. It's designed to be crushed under the muzzle device to create a tight, repeatable zero and prevent the device from backing off. The teeth grip the barrel and washer surfaces for positive engagement.

Does the Phantom 5C2 work well in prone shooting positions?

Yes. The 5-port design has no downward-facing ports, which reduces dust signature and muzzle rise when you're shooting from the ground. This makes it practical for prone precision work and low-position tactical drills.

Can I use this flash hider with a suppressor?

The facts provided don't specify suppressor compatibility. Contact Bosque Outdoors or YHM directly to confirm whether the Phantom 5C2 can be stacked with a suppressor on your setup.
