AR-15 Muzzle Device comparison

Andrew Tuohy of Vuurwapen Blog wrote a rather comprehensive article comparing muzzle devices for the AR-15. He captures the flash from the devices with a camera, videos the recoil and muzzle climb in slow motion as well as test for DB levels. He then quantifies the results in a nice tidy bar graph.

Check out the review.

    Am I the only person who couldn’t see the videos or photographs? Regardless, this is probably one of the most useful articles I’ve ever seen. If I read the charts correctly, the plain ol’ six dollar A2 device is perfectly cromulent.

      You’re not alone…

      I can’t see the muzzle flash pics/vids.

      • The color muzzle flash photos don’t have an associated video. All of the black and white videos are much further down in the article.

      I can’t see the videos on the Firefox browser, but they’re there on Internet Explorer.

      In place of photos on either browser, I see [slideshow_deploy id=’4758′]

    Excellent info. This is the content the should have.

    I seem to recall that Andrew Tuohy carried out this evaluation quite awhile back. If anyone is having difficulties on this site, try the original posting “AR-15 Muzzle Device Comparison” at

    Seen this article for a while back, and that was the basis of my decision to chose A2 for both 5.56 and 7.62, plus the fact that there is a whole slew of cans that fit to both of these since they are the generic default hiders for a variety of weapons.

    So just like I commented on many brake/hider articles before this one… A2 wins hands down for utility and performance as well as the nearly negligible price tag. And just as a bonus – it is by far the most compact one, and adds insignificantly to the OAL of the rifle.

    I do not care for one second if it loses the ridiculous “my brake looks just soooo badass” competition against the overpriced tacticool nicknacks.
    But again as with all tacticool, nothing practical about it and just as relevant to shooting as hip-hop to ballet.

    I run either vortexs or blackouts on my ARs (and a AK). Besides the flash elimination, they are super easy to clean (AND install) and the blackouts obviously work with my canned guns. Many people (including the army) hold them with disdain because they “ring”. If you ever have to use the damned rifle, I think that is the least of your concerns.

    You cant go wrong with either. If you are cheap and/or don’t feel like messing with it, the A2 works just fine.

    Anything else? don’t bother (yup, im serious).

    I’ve always thought BattleComps were cool and wanted one until I saw his testing. I’m really disappointed, and should thank him for saving me some money.

    what? no flaming pig? how could they forget the flaming pig?

    I read that article a few months ago and it’s the reason I plan to use Blackout flashhiders eventually. Between AAC’s own cans and the SilencerCo Saker, it’s nice to know that one of the best flash suppressors is also one of the best suppressor mounts.

    The real news here is that Vuurwapen Blog is back online, albeit with some missing images (so far). Andrew stated on Facebook that his hosting company couldn’t upload his 4GB backup file. He later stated that he got it to work by manually editing a 4GB txt file.

    Effin-A tunable comp. Don’t tell me it doesn’t work. Because it does…it’s tunable!
