dB Foam, when used as directed, provides a safe and effective means for increasing a suppressor's sound-reduction capabilities instead of wetting the suppressor with water. In commercially available sound suppressors dB Foam can reduce noise an average of 3-5 dB for 10-shot strings with the most noise reduction concurring with the first shot fired. This spray-on formulation is designed to displace moisture, lubricate removable components and is water soluble for easy cleaning. Once it has been applied to the interior of a suppressor, dB Foam will maintain its consistency for up to six months in storage. Inland products are distributed exclusively by MKS Supply.
MSRP: PM-22 Suppressor $189.95, dB Foam $19.95 - $29.95
At SHOT Show 2017's Media Day at the Range, American Rifleman editors had a chance to see the PM-22 close up (amid the noise a number other firearms being sampled), and you can see it here.
