Inland Firearms offers up a suppressor foam that really works! Decibel Technologies, LLC is a subsidiary of Inland Manufacturing and dB Foam is marketed exclusively by MKS supply, LLC.
Now for the good stuff! Over the years, suppressors have been additionally muffled with the use of some "liquids." The effect upon firing the gun is that the liquid became aerosolized and the particulates helped some to interfere with the gases and sometimes lowered the sound, but not reliably. But until now, an efficient and safe wet solution suppressor foam (already pre-aerosolized in the form of tough tiny bubbles) has not been commercially offered.
Many suppressors are pretty costly, so squirting water (little or no effect) or other liquids (some dangerous) into them is not a good idea.
dB Foam is a proprietary, low viscosity (thin), expanding water-soluble foam specifically formulated to do several things for all suppressors:
- Enhance suppressor efficiency
- Make the suppressor easier to clean
- Help reduce internal heat
- Lubricate metallic innards to help prevent corrosion
- Help protect the muzzle, bore and action from particulates that may be blown back into a firearm with a suppressor attached.
A small (½ second or so) shot of dB Foam will expand to fill the dead space in most suppressors with tough, sound-absorbing bubbles that testing shows will last for more than a week.
Tests of dB Foam used Mil-spec equipment in 5.56 and .308 calibers, and subsonic .22LRs and 147-grain 9mm rounds were fired from several handguns and suppressor systems. Results showed that, on average, dB Foam lowered the sound over ten-shot strings by 3-5 decibels - and, more importantly, up to 10 decibels for the first shot.
Follow user directions (basically, a quick squirt into the front of your suppressor), and the stuff works. It is that simple!
