Ron Norton, the man behind the Chiappa Rhino, is a restless sort. According to the man, the myth, the legend, he’s spent some of the last five years developing a product to lubricate and rust-proof suppressors. But wait! That’s not all! Ron’s db Foam stops “first shot bark.” Our man Foghorn explains . . .

“A silencer has oxygen inside of it. When you fire the first round our of a suppressor-equipped gun, the heat from the expanding gasses exiting the barrel burns up all of that oxygen. It creates some additional noise, called ‘first round pop.’ There’s no more oxygen in the can for subsequent rounds, so they’re quieter, relatively speaking.”

The db Foam suppresses a suppressor’s initial pop by replacing the air inside the can with . . . foam. Simply insert the straw into the can — but not the firearm’s bore — and spritz while pulling the straw back towards the opening.

Ron reckons the foam maintains optimum performance for ten shots and ten shots only. (The can has to cool down between applications.)

If you don’t consider eliminating a suppressor’s first round bark worth carting around a can of ballistic shaving cream, it’s still useful product for protecting your can during long-term storage (up to six months), keeping rust and schmutz at bay.

Of course, most suppressors are made of stainless steel or titanium, which aren’t prone to rust. But you can’t be too careful, can you? Pay the man $29.95 for a 16 oz. can or $19.95 for a 4 oz. can and you’re good to stow.

  1. I’ve never noticed first round pop. With rifles I wear earpro no matter what and with pistols I’m usually too busy marveling at how well the muffler actually works.

  2. Very cool idea. I’ll pick some up for sure. If it even helps he noise and lubes the baffle a little I’m sure it’s worth it for me.

  3. Wasn’t able to find the website for this product that details the noise reduction when using the product.

    I would assume its coming.

  4. Heat doesn’t burn up oxygen. This whole explanation of “first round bark” is, chemistrywise, nonsense.

    • That is because the explanation is wrong. Rarely does all the powder get burnt inside the barrel. The first round pop is what happens when the unburnt powder reaches oxygen in the silencer and starts to burn up. After that first round the oxygen inside the silencer is mostly used up so subsequent shots no longer get the first round pop unless you wait long enough for diffusion to result in the oxygen to return.

    • No scientist, I’m pretty sure you’re correct. Betcha guns work in outer space, although suppressors would not be helpful, no sound.

    • Yes, it does. I suspect that what’s burning inside a can during first shot are partially burned residues and gases like CO.

  5. Neat. Expensive though, and I feel like the effect can be replicated by something off the supermarket shelf.

    • As long as what you buy will firm up, and not cause rust or damage to either the suppressor or what blows back into your barrel.
      I’ve watched the blurb on guns and ammo and read other reviews it says you can leave it in for 6 months.
      I have a can on my Glock 41 for home protection, anything I can do to make it even a bit quieter in the confines of my home is worth it.

  6. Want to purchase the dbFoam in a 4oz can, but all I’ve found is the 16oz.

    Anyone got a link to purchase it?
