Sound Test Notes
- For autoloaders, port size and gas system length can affect sound results.
- Unsuppressed values are included as comparison baselines only.
- Testing equipment used for testing was a Dewesoft Sirius HS DAQ coupled with a PCB 377C10 microphone capsule with a 426B03 preamplifier, using a sample rate of 1 MHz (1 million samples per second). Data was exported through DewesoftX software.
- Sound measurements comprise 10 shots unsuppressed for baseline and 10 shots suppressed according to SAAMI Z299.6-2025 guidelines.
- Muzzle measurements were taken in accordance with SAAMI Z299.6-2025 at 1 meter left and 1.6 meters above earth, perpendicular to suppressor/muzzle exit, using grazing incidence.
- Shooter’s-ear measurements were taken using SAAMI Z299.6-2025 at 6 inches perpendicular to bore line on the ejection port side and 12 inches to the rear, and 1.6 meters (63") above ground.
- Ammunition used: Federal M855 for 5.56x45mm; Federal M80 for 7.62x51mm; Hornady 140gr ELD Match for 6.5mm Creedmoor; Hornady Leverevolution 160gr for 30-30 Win; CCI Standard Velocity 40gr for .22LR; Remington 250gr Core-Lokt for .338 RUM.
