SSS.6.108 - Rugged Razor762 and the Q mini FIX 300 BLK Subsonic

The Rugged Razor is a “semi-compact” 30 caliber machine gun rated rifle silencer that possesses moderate sound signature suppression performance with relatively low back pressure. The silencer is advertised to have extreme durability and has a reasonable weight for extreme duty-use silencers of its size, at a total system weight of 18.2 ounces as tested. System weight is reduced to 16.8 ounces with the M2 brake. On the short barrel 300 BLK platform, the Razor possesses suppression performance on par with other traditionally designed compact 30 caliber rifle silencers.

How would the Razor762 perform on your personal defense weapon?

SSS.6.76 - Rugged Razor556 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

The Rugged Razor556 is a “semi-compact” 223 caliber machine gun rated rifle silencer that possesses moderate sound signature suppression performance with relatively low back pressure. Relative to many dedicated 5.56mm bore silencers, it may be considered “full size.” The silencer is lighter than the Razor762 and quieter than the Razor762 on the MK18 5.56x45mm short-barrel rifle AR15 weapon system, on average. The Razor556 is advertised to have extreme durability and possesses a total system weight of 15.3 ounces, as tested.

In this review, the Razor556 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 Razor556 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.
