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.6.101 - CGS SCI-SIX and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle (Free Version)

The CGS SCI-SIX is a is a full-size 5.56mm machine gun rated rifle silencer constructed of DMLS (3D-printed) Inconel 718. It exhibits high performance on the MK18 weapon system and is demonstrated to be one of the most balanced high performance designs on the current market, with extreme durability and lighter weight than some legacy designs. The production variant is the result of a multi-tiered third party performance evaluation process in a solicitation that was created by the end-user entity SC IRREGULARS. It is the first CGS production rifle silencer to feature a dedicated muzzle device mount.

In this review, the SCI-SIX 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 SCI-SIX perform on your AR15 short barrel rifle?

SSS.6.18 - Intermediate Results Summary: Compact and Mid-Size .308 Rifle Silencers - Suppression and Back Pressure

The previous Sound Signature Reviews, up to and including Review 6.16, have featured various silencers on several host weapons. Eight of those reviews feature centerfire rifle silencers; two of which were tested in two configurations each due to modularity of the silencer body or end-cap. This is a comparative summary of the objective performance of those ten total configurations.

This Results Summary is part of ongoing PEW Science small arm weapon system sound signature research.

The data herein references the Suppression Rating and relative back pressure metrics which have been reported throughout the centerfire rifle reviews, to date, in order to frame objective flow rate characteristics of the silencers for their prospective use on semi- and fully-automatic small arms. This data is the first of its kind in the public domain and represents a direct contribution of PEW Science member-funded research to the state of practice.
