The HUXWRX HX-QD 556k is a compact 5.56mm machine gun rated rifle silencer that exhibits class-leading back pressure reduction with a notable balance of sound signature suppression performance that is competitive with many silencers on the market. It should be noted that the HUXWRX / OSS design requires gas path length to achieve efficacy. As a result, this “k” silencer is similar in overall length to some full-size dedicated 5.56mm rifle silencers on the market.

In this review, the HX-QD 556k performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a short barrel gas-operated rifle, which is an incredibly difficult task. How would the HX-QD 556 perform on your AR15 short barrel rifle?
