SSS.6.162 - Combat Application Technologies CAT/SC/B1 and the HK P30L (Free Version)

The CAT/SC/B1 (CAT SC) is a lightweight, highly advanced, and modular centerfire pistol silencer that exhibits extreme sound signature suppression performance for both operators and bystanders. The silencer’s combined performance, flow rate, and modularity, represent the most significant advancement in centerfire 9mm pistol suppression in recent history. The CAT SB-SHOCK technology, adapting characteristics from both SURGE BYPASS and DiVerge, results in maximizing performance in relatively small design envelopes; a significant benefit in suppressed handgun applications.

In this review, the CAT SC performance metrics depend upon suppressing a full-size handgun firing a full-power subsonic centerfire pistol cartridge. How would the CAT SC silencer perform on your self-defense handgun, in both long and short configurations?

SSS.6.159 - Combat Application Technologies CAT/DD/A1 and the Savage Model 10 PC .308 (Free Version)

The CAT/DD/A1 (CAT “Dirty Dave” or CAT DD) is a compact “K-sized” 7.62x51mm NATO rifle silencer intended for use on reciprocating weapons. The silencer exhibits a high flow rate and significant sound suppression for its size. Using a high pressure adaptation of CAT SURGE BYPASS technology, the CAT DD produces low relative FRP and is one of the most consistent compact 30-caliber rifle silencers evaluated in the research pedigree in this combustion regime.

In this review, the CAT DD performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 bolt-action rifle, and does it have performance traits that are appropriate for semiauto use?

SSS.6.148 - Combat Application Technologies CAT/MOB/A1 and the Heckler and Koch SP5 9x19mm Subgun (Free Version)

The CAT/MOB/A1 (CAT MOB) is a lightweight and highly advanced 36 caliber submachine gun silencer that exhibits extreme sound signature suppression performance. For its size and weight envelope, the MOB’s performance is even more significant. Notably, the CAT DiVerge technology in the MOB silencer appears to regulate the varied low pressure conditions throughout each stage of the silencer, reducing backpressure while simultaneously achieving maximum signature suppression. The CAT MOB exhibits the most advanced submachine gun suppression performance evaluated by the PEW Science laboratory, to date.

In this review, the CAT MOB performance metrics depend upon suppressing a subsonic centerfire pistol cartridge on a roller-delayed blowback submachine gun. How would the CAT MOB perform on your 9mm pistol caliber carbine (PCC)?

SSS.6.130 - Combat Applications Technologies CAT/WB/A1/718 and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle (Free Version)

The CAT/WB/A1/718 (CAT WB) is a compact and extremely advanced 5.56mm machine gun rated rifle silencer that exhibits significant back pressure reduction and sound signature suppression performance, for its size. Its sound suppression performance on both medium and short barrel 5.56x45mm rifles is significant. Notably, the CAT SURGE BYPASS technology in the silencer appears to balance high flow rate behavior with superior overall signature suppression. The silencer is available in two 3D-printed material options; proprietary Inconel alloy and Titanium. The weights of both models are notable. The CAT WB represents one of the most advanced systems evaluated by PEW Science, to date.

In this review, the CAT WB 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 CAT WB perform on your M4 with a 14.5-in barrel?

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.
