SCOUT REPORT
SilencerScout Sound Test
Our core performance metric. If this is your first time exploring our data, read our sound metering methodology to understand what these numbers are telling you. Every configuration is metered at two positions and both are shown side by side: SE (shooter's ear) and ML (muzzle, left side). Metered August 20, 2026.
A gunshot recorded on a sound meter is a pressure curve that spikes and decays over milliseconds. Peak decibels captures only the tallest point on that curve, ignoring how long the pressure stays elevated and which frequencies carry the energy. LIAeq100ms takes the whole curve, applies an A-weighting filter to approximate how the human ear responds across frequencies, then integrates the impulse energy over a fixed 100-millisecond window. The result is a single number: the level of a steady, continuous sound that would deliver the same A-weighted energy to your ear. LIAeq100ms is our leading metric. Peak decibels and impulse are shown alongside it for context.

About the Test Platform
Same .30-cal load, two very different hosts. 7.62x51 Lake City M80 is the reference cartridge for this battery — a plain 147gr ball load that is easy to source and easy to repeat — so the gap between the 16" AR-10 and the 20" bolt gun is the action itself, not the ammunition.
A gas gun vents a second report back through the ejection port and straight past your head; a bolt gun keeps everything sealed until you lift the handle. The last two columns are the small-frame AR-15s a 7.62 can spends much of its life bolted to: 5.56 Lake City M193 through a 14.5" barrel, and 300 BLK Hornady Black 208gr ELD Match subsonic through a 7.5".
Those two bracket the range. The 5.56 column is what you give up buying one can to cover both rifles, and the subsonic 300 BLK column is the quietest this suppressor will ever meter — no supersonic crack to hide behind, so what you read there is the can and nothing else.
The AR-10, bolt gun and AR-15 hosts behind our 7.62 tests — write-up not yet published.
First Round Pop
On the first shot, unburnt propellant mixes with the oxygen sitting inside the suppressor and burns a second time in the can. That secondary combustion often makes the round louder than the ones behind it. Once that oxygen is burnt off, follow-up shots settle into a quieter, steadier number. This is commonly called first round pop, or FRP. Because a hunter, marksman or defensive shooter may only ever fire one or two rounds, we isolate the first-round data rather than bury it in the average, and present it here. The magnitude of first round pop varies substantially across designs.

Efficiency Metrics
These metrics nest raw decibel performance in the important context of how well a suppressor performs for its size.
Quoted off 16" AR-10 · 7.62x51 Lake City M80. Each value is dB reduction ÷ the listed dimension, at shooter's ear (SE) and muzzle left (ML).

Tuning overhead
This metric captures the tuning overhead of the suppressor when paired with sound-mitigating part choices. A valuable metric for understanding what overhead you, the end user, have to push the performance envelope. Both rows are the same barrel and the same load. Only the parts used change.
