PWS MOD 2 FSC556 .223 1/2x28 Black Flash Suppressor
- Caliber-Gauge:
- 223 Remington / 5.56 NATO
The PWS MOD 2 FSC556 .223 1/2x28 muzzle device is a flash suppressor and compensator built for AR-15 shooters who demand both sight picture clarity and recoil control. Primary Weapons Systems engineered this .223 flash suppressor to handle the dual role: tame muzzle flash so it doesn't wash out your optics, while providing the stabilization benefits that help you land faster follow-up shots. Whether you're running drills at the range or working through a precision rifle course, the FSC556 delivers practical performance without the concussive overpressure punch that makes shooting near others uncomfortable.
The FSC556's port design is where PWS made its reputation—it achieves muzzle control comparable to dedicated brakes while keeping the blast signature manageable. That matters for shooters who train in groups, hunt in country where noise carries, or simply want to maintain situational awareness downrange. The suppressor-compatible design also fits select Gemtech HALO models if you're planning to run a can later.
At 2.5 ounces and 2.33 inches long with a 0.865-inch diameter, the FSC556 won't bloat your rifle's profile or throw off your balance. The 1/2x28 right-hand threads are standard for .223 Rem/5.56 NATO platforms, making this a straightforward bolt-on upgrade for any compatible AR upper.

Frequently Asked Questions
Will the PWS FSC556 fit my AR-15?
Yes, if your barrel is threaded 1/2x28 RH for .223 Rem or 5.56 NATO. This is the standard thread pitch for most modern AR-15 uppers in these calibers.
Is this compatible with a suppressor?
The FSC556 is suppressor-compatible and will work with select Gemtech HALO suppressors. Compatibility with other suppressors will depend on the model; consult your suppressor's documentation or reach out to our team if you have questions about a specific can.
Does it reduce flash better than a standard muzzle brake?
The FSC556 is designed to suppress muzzle flash enough to keep it out of your optics and line of sight, and delivers compensator performance at the same time. A dedicated suppressor will reduce flash more effectively, but this device balances both roles without the full bulk or regulatory requirements of a can.
What's the difference between a flash suppressor and a compensator?
A flash suppressor controls muzzle flash and blast signature; a compensator redirects gases to manage recoil and muzzle rise. The FSC556 does both—it's a hybrid design that gives you flash control plus stabilization benefits in one piece.
