Our 4 cavity Silicone mold is not new to the market, but the new plug upgrades allow you to cast both Sierra and JR cap blanks (each cavity measures 2.5″ x1″ x 7/8″).  The mold is not only versatile in its ability to cast a variety of blanks, but it comes with no embossed company name built-in. If you want your name to be on your blanks, it is a one-time $25.00 fee; send us a message from the home page.

This package comes with 2 medium plugs and 2 large plugs, and additional plugs are sold separately.

Epoxy resin is very hard on silicone, to get the most use out of these molds epoxy is not recommended.
