Dead Air

Sierra 5 KeyMo

This is our first impression of the Dead Air Sierra 5 KeyMo suppressor.

Since this suppressor was announced I have wanted to get my hands on one, being a Dead Air FanGirl and all. My first impression is positive as it comes in a nice box with a foam insert and it’s own proprietary three prong flash hider/keymo mount (A $90 bonus if you have to buy it separately). It also comes with a “flash hider” type endcap and a knurled body, similar to the Dead Air Wolverine. I’m looking forward to running it if the weather would ever cooperate. I will be running it on a Sig 516 (piston driven) AR type rifle with a 10 inch barrel. Should be fun. I will update once I get an opportunity to get to the range.
