dB Foam Suppressor Additive

[crays]

What say the hive? Anybody see this at SHOT? Any thoughts, opinions, ideas?

Inland Mfg dB Foam (https://www.inland-mfg.com/Inland-Suppressors/dBFoam.html)

From the website:

dB Foam, when used as directed is safe to use with most firearm suppressor designs and will significantly reduce the sound level of firearm suppressors. Independent testing using a variety of commercial suppressor designs averaged a 3-5 dB reduction with 10 shot strings of fire utilizing MIL-STD-1474E sound level testing procedures. The most significant reduction when using dB Foam was found with the first shot fired with dB reduction in some cases that exceeded 10 dB.

dB Foam has been formulated to maintain the foam consistency for up to 6 months of storage. This attribute will provide the great sound reduction when utilizing the suppressor for hunting and tactical applications.

dBFoam displaces water and provides rust inhibiting protection for the internals of your suppressors and firearms. dB Foam is water soluble, simply wash your suppressor in warm water and wipe dry after use.

dB Foam Lubricates as it protects. dB Foam provides a lubricating film that protects the internal components of suppressors with rust inhibiting properties. Residue that is blown back into the firearm action from the backwash of the suppressor will provide the same protection to the firearm bore and action.

MSRP: $29.95.00-16 oz / 19.95-4 oz

I want to try this stuff out. I think it's a cool idea but if it only lasts for 10 shots I'm not sure if it's all that useful.

For varmint control with some form of low light optic, sounds like a good idea. If' you're going to buy 1, get 2, i'll give it a try on one of my F1 cans. This way we can see before and after .

[izzy]

that makes sense if you're hunting of have some kind of tactical purpose for it, for me it's just fun and I'll try it anyways

where are you going to buy it from?

It said it lasted about 30 shots. The test strings were 10 shot averages. Will stay in the can about a week.

Isn't there already a type of foam that reduces the noticeable report from gun shots?

better but still not that great, guess a refill after a standard cap mag isn't that bad

LOL....there is - that's the selfish version. This is friendly to those around you.

Bad mojo to run centerfire rifle cans "wet" , the hydrostatic shock created does bad things . Pistol and rimfire work fine "wet"

Without spending the time to model it, I expect the foam is far safer due to its compressability in comparison to liquids.

It'd be interesting to see though.

Anything that is going to stick around for 6 months is going to have more consistency than " foam " and with the muzzle pressures generated with centerfire rifle cans no thanks . Pretty sure no suppressor MFG is going to warranty a split centerfire rifle can that has been run wet especially since most tell you not to do it .

Probably works fine in rimfire and pistol cans but so does water and most other liquid .

Water is about 62 lb/cf, air is about 0.07 lb/cf. Polyurethane foam is about 1 to 1.5 lb/cf (just for reference). There are numerous industrial foams with densities in the range of 0.15 to 1.0 lb/cf. All foams are compressible and are modeled closer to air than water in the field of Fluid Dynamics. There are in fact water soluble foams that can maintain a structure when desiccated of a carrier that have extremely low densities. I ran a few brief analytical models with some assumptions using high temperature flow models like I used to evaluate compensator performance.

It is very probable that this stuff can work if properly formulated and result in the same, more or less pressure to the baffles and shell of a suppressor. Collapsing the pockets robs energy and I was able to find several references to foams that would certainly do that and be a candidate for this application. That is not an endorsement, but I would not say that comparing it with the traditional notion of running a suppressor "wet" is valid.

Shane's response verbatim , Wow, dB foam, gonna have to get some of that. , I know how this was meant to be taken but take it for what you will
