The synthetic stock of my current rifle, I filled with two part epoxy. It was, and is fantastic. Balanced the gun, solid as a rock, no voids, deadened a lot of noise, and recoil. Downside, expensive right at forty or fifty bucks!! Not counting my time.
The Duct seal you are referring to. Is that the white elastomeric goop they seal the seams of sheetmetal ductwork in commercial applications?
Thanks Guys, I'm looking for an alternative to the expense, I sure do like the results.
Thanks,
Perry
