SSS.6.204 - Otter Creek Labs Infinity and 7.62x39mm Automatic AK-Pattern Rifles (Free Version)

The Otter Creek Labs Infinity is a severe-use mid-size 30 caliber rifle silencer with an advanced but flexible hybrid design. In the role of a 7.62x39mm AK-pattern rifle silencer, it is considered full-size. The silencer is user-configurable for different blast load flow states and allows the operator to adapt the system to a variety of host weapons. With a high early-time flow rate, the silencer is well suited to reduce system back pressure. When utilizing its vented 7.62 end cap that increases late-time flow rate significantly, the Infinity performs well on standard untuned AK rifles and produces balanced and efficient performance, regardless of barrel length. The Infinity is 3D-printed from Inconel alloy and is expected to offer significant durability for hard use.

In this review, the Otter Creek Labs Infinity performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on two AK-pattern gas-operated rifles, which is an incredibly difficult task. How would the Otter Creek Labs Infinity perform on your Bulgarian AK-pattern rifle with a 16.3-in or 12.6-in barrel?

SSS.6.202 - Zastava ZVUK and the 7.62x39mm Automatic Serbian AK-Pattern Rifle (Free Version)

The Zastava ZVUK is a 3D printed modern tribute to the Soviet Pribor Besshumnoy Stryelbiy (PBS) silencer system. Unlike the original PBS silencer designs, the ZVUK uses modern technology with a monolithic printed design possessing stepped baffles combined with Purposely Induced Porosity (PIP) under license, along with early blast chamber venting and secondary flow paths. These design differences result in significant pure suppression performance from the ZVUK and a higher gross flow rate than legacy systems.

In this review, the Zastava Arms ZVUK performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on an AK-pattern gas-operated rifle, which is an incredibly difficult task. How would the Zastava Arms ZVUK perform on your AK-pattern rifle with a 16.3-in barrel?

SSS.6.201 - Dead Air Wolverine and 7.62x39mm Automatic AK-Pattern Rifles (Free Version)

The Dead Air Wolverine is a modern tribute to the Soviet Pribor Besshumnoy Stryelbiy (PBS) silencer system and is intended to suppress weapons of Soviet origin, such as several AK-pattern rifle variants with semiautomatic and automatic fire.  Unlike the original PBS silencer design(s) the Wolverine uses modern baffle technology, materials, and construction.  However, when compared to the current state of the art, the Wolverine’s internal design is relatively conventional.  The signature suppression performance of the Wolverine, and its personnel hazard reduction, is relatively low when compared to many modern rifle silencers.

In this review, the Dead Air Wolverine performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on three AK-pattern gas-operated rifles, which is an incredibly difficult task. How would the Dead Air Wolverine perform on your Bulgarian or Yugoslavian AK-pattern rifle with a 16.3-in or 12.6-in barrel?

SSS.6.200- Research Supplement: Unsuppressed 7.62×39mm AK-Pattern Rifles as Silencer Test Hosts (Public Article)

Bolt-action weapons allow for the elimination of variables to study pure sound signature suppression phenomena. PEW Science is continuing bolt-action weapon testing, analysis, and research. Automatic weapons introduce additional sources of overpressure to atmosphere, namely from their breach during function, which is necessary for ejection. Since the introduction of automatic rifle signatures into the Standard in Public Research Supplement 6.51, and automatic subgun signatures in Public Research Supplement 6.85, additional weapon system variables have been introduced that influence the sound fields, as mapped by the measured muzzle and at-ear signatures. PEW Science is continuing the aforementioned bolt-action and automatic rifle weapon testing, analysis, and research. The purpose of this Public Research Supplement is to present a first-look at muzzle blast phenomenology for a new addition to the published host weapon systems in the Standard; AK-pattern rifles chambered in 7.62×39mm.
