Testing 30 Caliber Suppressors

Published on May 26, 2015
Duration: 13:40

This video scientifically tests various .30 caliber suppressors using industry-standard equipment like Bruel & Kjaer sound meters. It details the 'first round pop' phenomenon and why suppressors are tested dry. Results show significant decibel reduction on .308 rifles, with some .30 cal cans performing well on 5.56mm platforms, though most still exceed safe hearing levels.

Quick Summary

Professional testing uses Bruel & Kjaer sound meters to measure suppressor performance, avoiding inaccurate phone apps. Suppressors are tested dry to prevent warranty issues and corrosion, despite 'first round pop' potentially affecting initial readings.

Frequently Asked Questions

What is the purpose of testing suppressors dry?

Suppressors are tested dry to ensure consistent and repeatable results, as using wet media like water or grease can mitigate 'first round pop' but may void manufacturer warranties or lead to corrosion issues.

What is 'first round pop' in suppressors?

'First round pop' is the louder sound heard on the initial shot from a suppressed firearm. It's caused by the rapid combustion of oxygen within the suppressor's baffles before the internal atmosphere changes.

How accurate are phone apps for measuring suppressor noise?

Smartphone apps are generally not accurate enough for measuring firearm suppression levels. Professional impulse sound meters like the Bruel & Kjaer 2209 are required for reliable decibel readings according to industry standards.

Do .30 caliber suppressors work well on 5.56mm rifles?

Yes, .30 caliber suppressors can perform effectively on 5.56mm rifles, often providing sound suppression levels comparable to dedicated 5.56mm silencers, making them a versatile option.
