The FRP phenomenon cannot always be shown by viewing only the peak sound pressure. More detailed and direct comparisons are provided in Section 6.26.4 of this review.Īs typically indicated, first-round sound signatures always differ from subsequent shots, as the atmosphere within the silencer changes. This is one objective measurement that indicates the SOCOM762-RC2 exhibits relatively high gas flow rate and therefore relatively low back pressure characteristics. 308WIN ammunition, is measured to be significantly faster than silencers of similar size and Suppression Rating. The rise-time to peak impulse (peak momentum transfer potential) measured 1.0 meter left of the muzzle, of the SOCOM762-RC2, after the first shot when firing supersonic. 30 rifle silencers shown in public PEW Science testing, to date. PEW Science note: One notable observation from the measured data is the relatively short rise-time to peak impulse exhibited by the SOCOM762-RC2 in this test, when compared to that of all of the other. The consistency of the waveform amplitudes highlight the silencer’s overall sound performance consistency at the muzzle after the FRP, as well as the relative consistency of the tested bolt action rifle firearm configuration. The shape, timing, and magnitudes of the early-time pressure pulses and overall shape of the impulse waveforms measured at the muzzle, from shot-to-shot, are relatively consistent. PEW Science in-depth human inner-ear analysis of the waveforms measured at the muzzle indicates that the FRP may not be significant to bystanders. The fastest rise-time to peak impulse occurs in Shot 1, as expected. Note that after the initial impulse step peak occurs at approximately 30 ms, the impulse of Shot 1 has a steeper slope than the impulse of subsequent shots (Fig. The measured first-round-pop (FRP) is visible in both the pressure and impulse regimes, in peak amplitudes, timing, and wave shapes. Section 6.26.5 contains the review summary and subjective PEW Science opinions. Section 6.26.4 contains relative back pressure and Suppression Rating comparisons with selected. Section 6.26.3 contains an in-depth comparison of the sound signatures and flow dynamics of the two mount systems. Section 6.26.2 contains the results with the WARCOMP flash hider mount. Section 6.26.1 contains the results of the latest test with the SOCOM 3-Prong flash hider mount.
Federal XM80C 149gr ammunition was used in the tests.
Personal protective equipment (PPE), including eye and ear protection, is recommended for the operation of suppressed small arms, in general.īoth sets of test results in this Sound Signature Review are of the SOCOM762-RC2 on the Savage Model 10 Precision Carbine bolt-action rifle, chambered in. PEW Science does not recommend use of the WARCOMP mount on this platform, for most users. Readers who are not members of PEW Science, and are therefore not able to view the member data, are encouraged to note the Suppression Ratings at the ear in the above Rating graphic.

The SOCOM 3-Prong flash hider mount is non-ported and contains so-called “labyrinth seals,” the presence of which result in significantly different gas dynamics than a ported WARCOMP equipped SOCOM762-RC2 system at the mount interface.Ĭaution: The free version of this review does not show waveform data measured at the shooter’s ear. As a result, PEW Science repeated the test on the same SOCOM762-RC2 silencer on 2, this time with the SOCOM 3-Prong flash hider mount instead of the WARCOMP mount, with the same host weapon and ammunition. Significant anomalies were noted in the test. The SOCOM762-RC2 was first tested by PEW Science on 0 with the WARCOMP flash hider mount. Our brakes come in plain, fluted and with or without door-breaching teeth.This review contains results from two separate tests. Muzzle brakes reduce the recoil, so you spend more time shooting and less time worrying about a sore shoulder. AK 47 flash hiders and AK 74 flash hiders redirect the muzzle blast so you can stay on target. The AK flash hiders and AK 47 muzzle brakes in our selection deliver the performance you demand. DIES - DIE HANDLES - TAPS - CUTTING OILĬarolina Shooters Supply has the parts you need to tame that muzzle blast from your AK 47.
