    question: 556 suppressor for shorter than 10inch barrel

    I am looking to get info on suppressors, 556, that can be mounted on shorter than 10" barrels (that would not void the warranty), "mini" style preferred.

    I heard the ops inc mini is one, but didn't see any info on barrel size minimums on their website.

    Anyone have any info on this?

    Ops inc is no more, but Allen engineering will build you an identical can.

    Their cans are built for the 11.5" Colt barrels. The mount brings them a couple millimeters away from the FSB. When they were still in business, I don't think they warrantied them for anything shorter.

    Under 10 inch... I think you have just two viable options...
    SilencerCo will warranty the Saker down to 7.5" and Surefire down to 10".

    I have the Saker on a 7.5". VERY LOUD, but usable.

    That being said, if I knew then what I know now I would not have spent the time and money on it.

    I have an 11.5" with the Ops Inc M4S can and another 11.5" with the SOCOM mini. The SOCOM SB is supposed to be just a couple DB louder and is 1.2" longer.

    I like the Ops Inc more... shorter, lighter and with a better mounting system, but the brake is a bitch to install yourself (had mine done at ADCO).

    Also, while I can shoot the SOCOM rifle without the can (it has a flash hider, not a brake), I cannot do the same with the Ops. That brake is just a killer.

    No matter what you use you should always check for keyholes/tumbling to prevent baffle strikes.

    Thanks for the info.

    So there is no company that currently warranties down to 7.5 aside from the saker?

    I didn't know any company had barrel length restrictions. I know Huntertown warranties against anything but stupid.

    I don't think so... But I promise you that you will regret it as soon as you try it. the length/weight of the Saker offsets the length/weight you chop off going to 7.5"...
    7.5" barrel + 6.7" Saker = 14.2"
    10.5" barrel + 5" Surefire mini = 15.5"

    7.5" barrel + 6.7" Saker = Barely usable... definitely NOT "hearing safe"
    10.5" barrel + 5" Surefire mini = 15.5"... Acceptable sound reduction, better on unburnt gasses, stability, reliability, etc...

    1.3" is just not worth the sacrifice...

    Like I said before.. "If I knew then what I know now I would not have spent the time and money on it."...

    The Surefire SOCOM556-SB is designed for barrels under 10" It is not a "mini". I've used mine on a RA XCR 5.56 with 10" barrel without any problems.

    You might want to check that out a bit deeper.

    Directly from their Warranty page:

    Huntertown Arms warranties its silencers for life. If you are doing something that you can imagine yourself being laughed at on YouTube, think twice and then don't do it. Some examples of non-warranty claims:
    •Using on a barrel that is shorter than min. specification on product page (Check the specific suppressor's webpage.


    Then, directly from the Kestrel 556 page:

    Minimum barrel length: 11.5 inches

    Didn't check them all, but most of their cans list a minimum barrel length.


    Every manufacturer I've ever looked into has minimum barrel length ratings.

    Check out new Specwar K series (not released yet), or 762 Specwar. http://www.silencershop.com/shop/sil...o-specwar-556/ They are rated down to 7" barrel. I almost waited for them to come out, but got anxious and got 556 Specwar on way. Depending on 41p, K series might be coming too.

    ETA From link--“Our goal with the K version of the Specwar was to create the shortest and lightest hearing-safe 5.56mm silencer available,” noted Josh Waldron, CEO of SilencerCo. “This K version of the Specwar will still carry our lifetime warranty and can be used for full auto fire on barrel lengths down to 7 inches.”
