PWS FSC556 Flash Suppressing Compensator

The Flash Suppressing Compensator (FSC) Series of muzzle devices from PWS provides superior compensation characteristics combined with enough flash suppression to keep the flash out of your optics and line of sight. Designed for both competitive and tactical use, the FSC Series allows for superior muzzle stabilization and aids the shooter in faster follow-up shots and accuracy.

The unique port design of the FSC Series yields muzzle control that meets or exceeds the performance of the best muzzle brakes on the market without the teeth-rattling overpressure indicative of other brakes and compensators.

All of the FSC Series muzzle devices have been classified as a non-flash suppressing device by the BATFE, thus removing any restriction from assault weapon ban states or provinces. A copy of this document is available upon request or on our website at

A PWS signature product, the FSC 556 ships standard on the FNH® SCAR® 16S. Coupling flash suppression with muzzle control, the FSC 556 is an ideal compensator for putting a high volume of rounds on target.

    everything it says

    Product performs very well. Shipping was really fast as well. The only downfall of the product itself was installing it with all the various shims.

    Better than I expected

    Posted by Austin on 8th Dec 2013

    Easy to install. Ran 60 rounds though it all double taps and the barrel rise was next to nothing. As for the sound, I notice a large decrease in it over the old A2 bird cage as I had another AR with one still installed and did the side by side test. This is well worth the money and SKD did a great job with processing and shipping.

    Looks Awesome

    Posted by Steve L. on 10th May 2013

    Went on very easily after determining how many shims to put in. Took a few tries, but once on fit was flawless. Definitely looks better than the stock A2 that was on before. Haven't shot the rifle with it yet, but I don't foresee any issues.

    Quality, Just not what I needed.

    Posted by Tim on 14th Dec 2012

    I have no doubt that this is a good comp, I've used one before on another gun. However, this was not specifically what I needed as I needed the SM556 that would fit on the older HALO(S07 prefix) and the description that SDK uses is the same as the description on the Gemtech website that it will fit this model, it doesn't. I realize that this is NOT the fault of SKD and I am happy with the purchase and shipping from SKD I just wish Gemtech got the description correct.

    Muzzle brake/flash suppressor

    Posted by Ken on 27th Mar 2012

    Have purchased and used several different types on different weapons. This particular style/model works best for me on a variety of different platforms, from AR, AK, and an M1A. Well worth the money.
