SSS.6.169 - Research Supplement: Low Back Pressure 5.56 Silencer Performance - Flow-Through vs. SURGE BYPASS, PIP, and LBP. Head-to-Head Detailed Comparisons (Members Only)

Six 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 high flow rate characteristics and relatively high operator (shooter’s ear) Suppression Ratings on the untuned MK18 5.56x45mm NATO MK18 weapon system. The six silencers behave differently, even despite some of them exhibiting similar performance quantified by the PEW Science Suppression Rating. Their 5.56 MK18 suppression performance provides an excellent case study comparing current “low back pressure” rifle 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. However, there are significant exceptions. Hybrid designs have the potential to exhibit high performance in multiple regimes.

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 six low back pressure 5.56 rifle silencers that use various technologies to suppress AR15 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.

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

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?
