Home Forums Hunting & Shooting Hunting Rifles What filler for a hollow synthetic stock?

Or, do like Ruger and just jam a chunk of styro beadboard in the stock. That's what they do with the American. But certainly not effective.

The expanding foam fills the entire cavity 100%. For voids or recesses in the forend area, black silicone rubber caulk works well. Not nearly as heavy as bedding material, and simple to shape and smooth while wet to the shape it will be when dry.
