EXM Innovations sent in this video testing the decibel levels of their Custom 6-inch and 4-inch Amplifiers. Designed like cans (or suppressors), these do the opposite on what cans do, increase the sound volume of airsoft guns with fired. With a decibel meter, Mike shows the increase on a Cybergun Colt 1911 Pistol, KWA KMP9 GBB, and the G&G GR 15 Raider AEG.
