SSS.6.103 - Research Supplement: The Quietest 5.56 SBR Silencers - Taming the MK18, Part 4 - HUXWRX vs. Otter Creek Labs vs. CGS vs. Surefire (Article Preview)

Five silencers evaluated by PEW Science are included in this members-only Research Supplement to examine relative First Round Pop (FRP) and overall sound signature suppression performance characteristics. The five silencers were selected for their high average sound suppression performance at the muzzle or shooter’s ear on the standard PEW Science MK18 test host weapon system. All five silencers induce differing hearing damage risk to the shooter and bystanders on this weapon platform, on average.

This research supplement is intended to provide more information to PEW Science members with regard to specific sound signature characteristics of the tested configurations in the aforementioned reviews, and to help frame objective loudness comparisons between five silencer configurations exhibiting differing sound suppression performance on the MK18 weapon system. Both the FRP and average sound signature suppression regimes are examined. This supplement is part of ongoing PEW Science small arm weapon system sound signature research.

SSS.6.64 - HUXWRX HX-QD 556k and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)

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?

SSS.6.54 - OSS HX-QD 556 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)

The OSS HX-QD 556 is a full-size 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. The HX-QD 556 is also offered in a titanium version which reduces the weight of the system by 4.4 ounces. Users should note that full-size 5.56mm rifle silencers are often smaller than their full-size 7.62mm (.30) counterparts.

In this review, the HX-QD 556 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?

SSS.6.41 - OSS HX-QD 762 and the Savage Model 10 PC .308 (Free Version)

The OSS HX-QD 762 is a mid-size, relatively heavy, and durable .30 rifle silencer that exhibits class-leading back pressure reduction with a notable balance of sound signature suppression performance in the supersonic flow regime. Users should note that most silencers exhibit significantly different sound suppression characteristics in different flow velocity regimes, i.e. when suppressing supersonic vs. subsonic cartridges. This sound suppression performance variation, across different flow regimes, is more pronounced with silencers possessing high flow rate (low back pressure) characteristics, like the HX-QD 762.

In this review, the HX-QD 762 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 deer rifle?
