    10 stars

    This gets 10 out of 5 stars! I can't say enough good things about this comp/brake. I've bought 7 or 8 of the AR15 versions and 1 of the AR9 version for my PSA AKV-9. They work extremely well, keeping you on target. As with any brake I wouldn't recommend standing the next to the shooter, although I have to admit I like it ; ) On top of all that, they're the most budget friendly muzzle device on the market and they look great!!! Just buy and try, you won't be disappointed!

    This is my second Venom comp, and I love it. I will for sure get another one or two in the future. Nothing but the best from my Home State!

    Very well machined and coated. Haven't had a chance to test it yet. Other reviews were favorable.

    Best Accessory I have ever bought!!!!

    Posted by Rick Liebespach on Jun 12th 2020

    I bought this for my KelTec Sub 2000. The stock S2K had quite a bit of kick, considering it is only a 9mm. I just got back from the range, where I shot my S2K for the 1st time with the AR-9 Viper Compensator.
    What a difference!!!
    The S2K now has a recoil close to a .22lr..... it is maybe 80% less than it was before! (at least it feels like that to me)
    I hate to say something that may result in this costing someone else more money (I paid $22.50), but this would have been money well spent at twice the price!
    If there is ever another product I need/want, that they have.... I"m buying from them!

    AR 9 Viper Comp

    Posted by Dennie Vega on May 14th 2020

    Looks great, well made and quality machined. Venom Defense always has fast shipping and great service too. The comp works well regarding compensation and makes it easier to stay on direct, especially considering how jarring direct blowback can be, even though in this case it's only 9mm. I used this one on my PSA AKV and it looks DOPE! I'll be purchasing another for my PTR 9K as soon as it arrives at my FFL (no Im not an MP5 purist...). Great job guys. I've also purchased the Mjolnir pistol grip for one of my AR builds and love it too.
