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)

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.6.160 - PTR VENT 1 and the Savage Model 10 PC .308

SSS.6.160 - PTR VENT 1 and the Savage Model 10 PC .308

The PTR VENT 1 is a lightweight and highly advanced 30 caliber rifle silencer that exhibits extremely high sound signature suppression performance. The combination of performance observations noted in this test report demonstrate that the VENT 1 exhibits performance that far exceeds that of typical rifle silencers. The consistency of the measured signatures is also extremely notable. This iteration of Purposely Induced Porosity (PIP) technology in the silencer, along with other portions of its design, represent further 3D-printed advancement in the suppressed small arms state of practice.

In this review, the PTR VENT 1 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge; no easy task. How would the silencer perform on your .308 deer rifle?

SSS.6.135 - PTR VENT 3 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

SSS.6.135 - PTR VENT 3 and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

The PTR VENT 3 is a full size 5.56mm machine gun rated rifle silencer that exhibits significant sound suppression and back pressure reduction.  It is lightweight, possesses adaptable mounting, and exhibits some of the highest signature suppression performance on the standard MK18 weapon system of any silencer evaluated by PEW Science, to date.  The performance of the Purposely Induced Porosity (PIP) technology in the silencer, along with other portions of its design, is notable and represents further 3D-printed advancement in the suppressed small arms state of practice.

In this review, the PTR VENT 3 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 PTR VENT 3 perform on your AR15 short barrel rifle?

SSS.6.131 - PTR VENT 2 and the Heckler and Koch SP5 9x19mm Subgun

SSS.6.131 - PTR VENT 2 and the Heckler and Koch SP5 9x19mm Subgun

The PTR VENT 2 is a full size 9mm silencer that exhibits significantly high sound signature suppression performance and low backpressure. Although it is intended for use on submachineguns, at 8.5 ounces and 7.6 inches long with no mount, it is close in size to many full size 9mm pistol silencers. The performance of the Purposely Induced Porosity (PIP) technology in the silencer, along with other portions of its design, is notable and represents further 3D-printed advancement in the suppressed small arms state of practice.

In this review, the PTR VENT 2 performance metrics depend upon suppressing a subsonic centerfire pistol cartridge on a roller-delayed blowback submachinegun. How would the PTR VENT 2 perform on your 9mm pistol caliber carbine (PCC)?
