Adams Arms Dissipator Rifles and Uppers

    Adams Arms recently debuted their new line of Dissipator rifles and uppers. What’s a Dissipator you ask? It’s essentially an AR-15 with a 16″ barrel and a rifle-length gas system. Why would you do that? Mostly for the benefits of the longer rifle-length sight radius and shorter and more maneuverable 16″ carbine barrel. And because it looks pretty cool. Here is a pretty good read on Dissipator AR-15s.


    Adams Arms new Dissipators use their lightweight Ultra Lite VooDoo 16.5″ barrel coupled with their AR-15 short stroke piston system and Magpul MOE furniture. They also come with a low mass Adams Arms bolt carrier group that’s 21% lighter than their other carriers, weighting in at just 7.5 ounces. According to Adams Arms their Dissipator uppers and rifles run cleaner and cooler all the while maintaining a very low felt recoil pulse. Their Dissipator upper retails for $815.38 while their Dissipator Rifle retails for $1326.32, both come with a lifetime warranty from Adams Arms.
