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.6.196 - Otter Creek Labs Infinity and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle (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 5.56 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 may perform well on semiautomatic platforms even in its most restrictive configuration. For sensitive platforms, the user may fully vent blast loads from multiple stages of the silencer, lowering back pressure to a minimum for this design. The Infinity is 3D-printed from Inconel alloy and is expected to offer significant durability for hard use. The vented end cap configurations of the Infinity produce performance that scales well with increasing barrel lengths.

In this review, the Otter Creek Labs Infinity performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the Otter Creek Labs Infinity with three of its different end caps perform on your M4 with a 14.5-in barrel?

SSS.6.184 - Research Supplement: The Quietest 9mm Silencers - MP5 Silencer Detailed Loudness and Tone Comparisons (Article Preview)

Eight silencer configurations 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 silencers in this group were selected due to their use on the HK MP5 submachine gun, and other pistol caliber carbine (PCC) platforms. The eight silencers behave differently, even despite some of them exhibiting similar performance quantified by the PEW Science Suppression Rating. Their 9mm MP5 suppression performance provides an excellent case study comparing current 9mm MP5 silencer technology.

Typically, silencers possessing a high flow rate also possess lower sound suppression performance with subsonic ammunition and potentially lower bystander suppression performance, in general. Also typically, silencers possessing a lower flow rate (higher back pressure) can reduce the level of operator protection by increasing ejection port blast. There are exceptions to these observations, and hybrid designs have the potential to exhibit high suppression performance in multiple combustion regimes while also reducing back pressure.

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 analytical test reports and to help frame objective loudness comparisons between eight 9mm suppressors that use various technologies to suppress 9mm weapon signatures. Both FRP and total sound signature suppression regimes are examined. This supplement is part of ongoing PEW Science small arm weapon system sound signature research. PEW Science thanks you for your support.
