New Surefire WARCOMP 556 CTN Flash Hider/Compensator Hybrid Released

Manufacturer Surefire has formally announced a new variant of their successful Warcomp combination flash hider/compensator. The new muzzle device, called the Warcomp 556 CTN, sports a closed six tine “birdcage” style flash hider configuration, versus the original Warcomp’s open three tine configuration. This change is highly reminiscent of the change from the M16’s initial production three tine flash hider to the six tine A1 “birdcage” flash hider, which led to the now familiar four tine closed bottom A2 flash hider.

Unveiled to a limited audience as early as late last year, the Warcomp 556 CTN was reportedly developed at the request of a military unit that wanted the same combination of flash suppression and compensation that the Warcomp provides, but with a snag free closed profile. The possibility of the open tines snagging on gear and jungle foliage was also the reason for the move from the three prong early M16 flash hider to the birdcage typical of rifles from the latter Vietnam War period.

The Warcomp 556 CTN evidently does not suppress flash quite as well as its open tine counterpart, as seen in the video embedded below. However, this is not unexpected: Open tine designs do generally suppress flash better, due to the different way they handle escaping gases at the muzzle. Therefore, the closed tine design should be considered to trade off the best possible flash suppression for a snag free profile.

    I am never going to stop loving the commentary you place in the article tags…

    “flash suppression is really cool but to be honest I’d rather my muzzle not snag on crap, here we see a rare nathaniel f press release in the wild, unless I’m dueling the legendary samurai musashi and I’m all out of ammo and need to catch his blade between the prongs of my flash hider I guess”

    • The “snag” and “samurai” ones were originally one tag, but they literally wouldn’t let me add a tag that long. 🙁

        #1stWorldProblems, amirite?

  • Old Tofu

    expensive knock off of the a2 birdcage , no thanks

    • Patrick Karmel Shamsuddoha

      its also a suppressor mount for surefire cans

      • Old Tofu

        we need to progress to the point where adding the word suppressor doesn’t mean licence to print money , it’s a $40 part at best

        • Scott Wagner

          I’m sure surefire would love to hear how you could cut the cost of production to the point that they could sell it for $40 and still make a profit.

          • I wunder

            Easy, stop adding $80 to the price and sell it openly instead of as the latest ar add on to the tactitards.

          • Machinegunnertim

            Also, move out of Commiefornia. Production costs will drop significantly.

        • Silencer mounts are typically made of much tougher materials than your average muzzle device.

          For example the AAC 51T Blackout mount is made out of inconel. While the non-mount version is made out of 17-4 Stainless steel.

  • I wunder

    Why would anyone buy this? Are they too retarded to drill holes in the top of a standard birdcage they likely already possess?

    • Patrick Karmel Shamsuddoha

      its also a suppressor mount

      • I wunder

        So are those 1/2×28 threads that this rip off screws onto. Not counting that there are clamp on suppressor options for plain jane birdcages. This is a 40ish dollars worth of merch overpriced for the tacticool market. More so, this product is trying to solve a problem that doesn’t even exist.

      When you see them used side by side against a bird cage in low light/night its military application is pretty obvious especially if you don’t like your location being identified. There is also a noticeable difference in jump mitigation especially with double taps or bursts.

      Drilling holes in a bird cage if anything would be retarded, it would offer little in comparison apart from probably compromising its integrity. The holes, their size and location is important to to how it functions. The compensating portion of the WARCOMP’s is a separate chamber prior to the suppression section which is why it works well as a comp.

      Yeah if your a civi probably not much application or need where as for a soldier it would be a really good addition to their kit.

        Compensators aren’t that complex. Chamber? If there is one it is awful tiny. If drilling holes is so complex explain all the open class guns in uspsa. Common sense dictates drilling the wholes on top and or the sides of the piece. Size of wholes is rather obvious. The only touchy part about it is if you want them drilled at a speciffic angle, 11ish degrees is pretty common. Who hasn’t made a compensator from the ‘nade launcher on a Yugo Sks?? Or are you the type who bought Tapco’s “yugo comp”, an identical unit as to what could have been turned out with a drill and common sense?

        • jono102

          No need to buy or bubba some up when your issue rifle comes with WARCOMP’s.
          All my personal rifles have suppressors so its not generally an issue either way. A lot of breaks etc on the market are more about looks than purpose.

      • Old Tofu

        he drank the kool aide

    • Edeco

      I could make holes but doing a neat job would be a few hours work. Not cost effective. Also I don’t think it’s that simple.

      Another classic bit of hillbilly gun wisdom from the Rocket Scientists in the firearmsblog comment section

  • Rnasser Rnasser

    Veeery similar to Taiwan’s T65K2 (M16A2 clone) flash hider/compensator.

    BUT, the T65K2 is from the mid 80’s…
