In addition to offering superior compensation characteristics, PWS FSC Series provides 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.

    Perfect Compensator

    This compensator looks fantastic on my AR. Much nicer than the standard birdcage type. But aside from appearances, it works great. Just as advertised.

    I have this on a bcm ewl and it dominates. It makes a world of difference over a standard a2 birdcage

    Great Comp

    Arrived quick, easy install. Only put about 100 rounds through it so far but it does a great job keeping the barrel down.

    PWS comp

    I have this comp on every one of my BCM complete rifle or upper. Love this comp with or without running my Gemteck halo can.

    still one of the best

    i have a couple of these in various calibers.

    they work. still one of the better rated combo devices with a good balance of effectiveness - remember that everything's a trade off.

    for anyone that complains they're too loud, keep this in mind:
    they are quieter than "true" brakes by far (sjc titan, JP Recoil Eliminator, etc.). the Y-Comp is particularly brutal - FSC is a quiet little mouse in comparison.

    i've shot in class next to all manner of muzzle devices. BCE is annoying, too. but hey - we're shooting CENTERFIRE rifles - what do we expect?

    still rather sit next to a PWS/BCE/etc. than a .30-06 or .300 win mag.

    i can see where tac teams might eschew comps like this (shooting in a house, literally next to the muzzle, etc.), but for us normal joes, no problem.

    and, relatively speaking, they're a bargain compared to BCE, KAC & the rest.

    Great compensator!

    Ok, so it have only fired AR's with A2 birdcages, but the difference in muzzle movement for quick follow up shots is ridiculous! I have this pinned and welded on a 14.5in middy from BCM, and it fires wonderfully. I don't feel like it is much louder than a standard birdcage, but that's just my opinion. Besides, even if it was louder, who cares? It's not supposed to be a suppressor.
