Inland MFG ILMDB16 dB Foam Suppressor - Rust & Corrosion Inhibitor, 16 oz Can

Inland Manufacturing's dB Foam Suppressor treatment is a specialized 16 oz aerosol designed to reduce suppressor sound signature while protecting your hardware from rust and corrosion. If you run a suppressor for hunting, tactical training, or any serious shooting, this foam addresses two problems at once: it measurably cuts muzzle report and keeps internal suppressor components and firearm actions protected from moisture and oxidation.

The foam works by coating suppressor internals with a water-displacing, rust-inhibiting film. Independent testing showed an average 3–5 dB reduction in sound level across various commercial suppressor designs using 10-shot strings and MIL-STD-1474E test procedures. First-shot reduction was particularly notable, with some tests exceeding 10 dB of attenuation on that critical first round. The foam maintains its consistency for up to six months in storage, so a single can lasts through a full season of use.

Application is straightforward: spray dB Foam into your suppressor as directed, and it deposits a lubricating, protective film on all internal surfaces. Any backwash that makes its way into your rifle's action or bore carries the same corrosion inhibition properties, adding an extra layer of protection downrange. Cleanup is easy—warm water and a wipe are all you need to rinse the suppressor and prepare it for the next range trip or hunt. The water-soluble formula means no harsh chemicals or specialized solvents required.

For shooters in humid climates or those running suppressors hard during the season, dB Foam is a low-cost way to squeeze extra performance from your can while keeping rust at bay.

Frequently Asked Questions

Will dB Foam work with any suppressor?

dB Foam has been formulated to be safe with most commercial suppressor designs. Testing was conducted across a variety of mainstream cans. Always follow the application instructions on the product.

How much sound reduction should I expect?

Independent testing using MIL-STD-1474E procedures showed an average reduction of 3–5 dB across tested suppressor designs. First-shot reduction was often more dramatic, with some tests showing reductions exceeding 10 dB on the initial round.

How do I clean my suppressor after using dB Foam?

Simply wash your suppressor in warm water and wipe it dry. The foam is water-soluble, so no special solvents or cleaning agents are needed.

Does dB Foam provide any corrosion protection to my rifle?

Yes. Backwash from the suppressor carries the rust-inhibiting film into your firearm's action and bore, providing corrosion protection to those internal components as well.
