SSS.6.121 - PWS BDE 762 and the Savage Model 10 PC .308

The PWS BDE 762 is a modular 30 caliber rifle silencer that may be configured as full-size or compact. The silencer possesses relatively high suppression performance in both its longest and shortest configurations, on a centerfire rifle. It is a titanium silencer of hybrid design, constructed with both DMLS and traditional subtractive manufacturing. With five different configurations, the BDE 762 is relatively unique as a modular rifle silencer and also possesses a modular rear mounting interface that may be used with a variety of mounting solutions and muzzle devices.

SSS.6.120 - Combat Application Technologies CAT/ODB/A1/718 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

The CAT/ODB/A1/718 (CAT ODB) is a relatively compact and extremely advanced 30 caliber machine gun rated rifle silencer that exhibits significant back pressure reduction and sound signature suppression performance, for its size and caliber designation. Its sound suppression performance on a short barrel 5.56x45mm rifle is significant. Notably, the CAT SURGE BYPASS technology in the silencer appears to balance high flow rate behavior with superior overall signature suppression, even when over-bored for the cartridge. The silencer is available in two 3D-printed material options; proprietary Inconel alloy and Titanium. The weights of both models are notable. The CAT ODB represents one of the most advanced systems evaluated by PEW Science, to date.

In this review, the CAT ODB 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 CAT ODB perform on your AR15 short barrel rifle?

SSS.6.119 - Aero Precision Lahar-30L and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

The Aero Precision Lahar-30L is a mid-size 30 caliber precision rifle silencer that should be considered full-size or oversized relative to dedicated 5.56mm silencers. The Lahar-30L possesses significant sound signature suppression performance in this combustion regime, possesses an Inconel blast baffle, may be used on machineguns, and has no barrel length restrictions. Although high performance, the Lahar-30L exhibits higher back pressure than the shorter Lahar-30 variants, which may require weapon tuning for optimal signature reduction or weapon operation.

SSS.6.118 - AAC Ti-RANT 9M-HD, 9M, 9 and the HK P30L

The AAC Ti-RANT 9M-HD is preceded in development, design, and distribution by two legacy models; the AAC Ti-RANT 9M (2017) and the original AAC Ti-RANT 9 (circa 2009). At the time of distribution, the original Ti-RANT 9 was colloquially referred to as the “quietest 9mm centerfire pistol silencer” available. The publication of this case study in the Silencer Sound Standard research pedigree, by PEW Science, is intended to recognize the historical significance of the Ti-RANT 9 family of silencers and to provide a state-of-the-art performance evaluation of the models on a modern host firearm.

In this review, all AAC Ti-RANT 9 variant performance metrics depend upon suppressing a full-size handgun firing a full-power subsonic centerfire pistol cartridge. How would any AAC Ti-RANT 9 silencer perform on your self-defense handgun?

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 (Members Only)

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 Thunder Beast Dominus-SR is a mid-size and lightweight 30 caliber machine gun rated rifle silencer. As a 5.56mm machine gun rated rifle silencer, it may be considered full-size. The Dominus-SR reportedly exhibits significant durability for a titanium rifle silencer, through the use of its engineered sacrificial steel muzzle brake mount. The signature suppression performance of the silencer on the short-barrel MK18 is not as balanced as some other tested rifle silencers, due to its flow rate and other signature factors, examined in this test report.
