Primary Weapons Systems MOD 2 FSC556 Muzzle Device .223 1/2x28 Black
The Primary Weapons Systems MOD 2 FSC556 Compensator is a patented, battle-proven muzzle device engineered to deliver superior recoil reduction and effective flash suppression for .223/5.56 rifles — making every follow-up shot faster and more accurate.
- Dramatically reduces muzzle rise and felt recoil for faster target reacquisition
- Secondary flash suppression keeps muzzle flash out of your optics and sight picture
- Unique port geometry minimizes distracting overpressure felt by the shooter
- Built from tough 4140 steel with FNC LIFE HD finish for long-term corrosion resistance
- Standard 1/2x28 thread pitch fits most AR-15 and .223/5.56 rifle barrels
- Compact 2.3" profile and lightweight 2.3 oz design won't upset your rifle's balance
Who This Is For
The PWS MOD 2 FSC556 is ideal for competitive shooters, tactical users, and serious AR-15 enthusiasts who demand a real performance advantage at the muzzle. Whether you're running drills at the range, hunting in low-light conditions, or pushing your rifle's split times in competition, this compensator delivers meaningful recoil management without sacrificing flash control — a rare combination in a single muzzle device.

Frequently Asked Questions
Will the PWS FSC556 fit my standard AR-15 barrel?
Yes. The FSC556 uses a 1/2x28 right-hand thread pitch, which is the standard threading found on the vast majority of AR-15 and .223/5.56 rifle barrels sold in the United States. Simply remove your existing muzzle device and thread the FSC556 on with a crush washer or peel washer (sold separately) to achieve proper timing and a secure fit.
How does the FSC556 compare to a standard flash hider or muzzle brake?
Unlike a traditional A2 flash hider that focuses almost entirely on flash suppression, or an aggressive muzzle brake that prioritizes recoil reduction at the expense of concussion, the PWS FSC556 is specifically engineered to do both. Its patented port design vents gases upward and to the sides to counter muzzle rise, while simultaneously directing flash away from the shooter's line of sight — giving you the functional benefits of both device types in one package.
Is the FNC LIFE HD finish durable enough for hard use?
Absolutely. FNC (Ferritic Nitrocarburizing) LIFE HD is a hardened surface treatment applied to the 4140 steel body that significantly improves wear resistance, corrosion resistance, and overall durability compared to standard bluing or phosphate finishes. It's well-suited to the high heat and pressure environment at the muzzle and is designed to hold up through thousands of rounds of sustained use.
