SSS.6.124 - Research Supplement: Subsonic 300 BLK Suppression Performance - Flow-Through vs. Forward Flux vs. SURGE BYPASS vs. Conventional Silencers. Head-to-Head Comparisons (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 silencers in this group were selected for their relevance to the three rifle silencer technology classes: Conventional, High Flow Rate, and Hybrid Design. The five silencers behave differently, even despite some of them exhibiting similar performance quantified by the PEW Science Suppression Rating. Their subsonic 300 BLK suppression performance provides an excellent case study comparing current rifle silencer technology.

Many silencers exhibit significantly different performance when using supersonic and subsonic ammunition. In general, increasing gross flow rate through a silencer can significantly reduce signature suppression performance, particularly with subsonic ammunition.  However, certain designs may significantly outperform others in this regard.  Quantifying these performance differentials is essential for characterizing hazards to the system operator and bystanders.

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 30 caliber rifle silencers that use various technologies to suppress subsonic 300 BLK sound 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.

SSS.6.115 - Research Supplement: Flow-Through Silencers vs. Conventional Silencers. Head-to-Head Detailed Comparison - Nomad-Ti vs. FLOW 762 Ti vs. Thunder Chicken (Article Preview)

Three 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 silencers in this group were selected for their very similar holistic sound suppression performance; their similar PEW Science Suppression Rating on a supersonic centerfire bolt action rifle. The three silencers behave differently, despite their similar performance. Silencers with similar suppression performance sometimes have very different flow restriction, or back pressure, partially characterized by the PEW Science Omega Back Pressure Metric. These are three examples of such silencers.

The Suppression Rating is a Damage Risk Criterion (DRC). As such, it characterizes the postulated risk of hazard to bystanders, or the weapon operator, from a suppressed small arm weapon system. Despite achieving a similar Suppression Rating, some silencers may have certain signature characteristics that differ from others, and those differences are of interest to users.

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 three supersonic 308 rifle silencers that possess similar holistic sound suppression performance. 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.

The HUXWRX FLOW 762 Ti is a relatively compact and lightweight 30 caliber machine gun rated rifle silencer that exhibits significant back pressure reduction and sound signature suppression performance, for its size. Its sound suppression performance on a short barrel 5.56x45mm rifle is significant. Notably, its sound suppression performance at the shooter’s ear on a .308 bolt action rifle is competitive with that of advanced conventional baffle silencers. The silencer is constructed of 3D-printed Grade 5 Titanium and represents one of the most advanced systems evaluated by PEW Science, to date.

In this review, the FLOW 762 Ti 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 HUXWRX FLOW 762 Ti perform on your AR15 short barrel rifle?
