Anyone ever tried this? It seems to me that if you could get the gel to retain its structural integrity during shots, it'd be absolutely amazing at dB reduction. Its usable lifespan is going to be very poor unless you use squeaky-clean propellants, so you'd probably have to live somewhere that doesn't have gigantic taxes on suppressor parts. Machining can be done with a drill bit if you are so inclined, but if you're trying to work with aerogels for the first time, note that the dust presents a small health hazard.

Have you ever actually seen or held a piece of aerogel?

I've played with Aerogel. It's brittle, extremely porous and liquid (read: humidity) will absolutely destroy it.

My point exactly. filling any space in a suppressor with Aerogel, to paraphrase Bender, Would be like bringing a rubber band gun to a Howitzer shoot off.
