Spartan are creating an integrated solution for the rifle adapter. This adapter requires a 19mm (3/4") hole drilled to a depth of 15mm. The adapter includes a stainless magnetic plate in the bottom to attract the magnet. The adapter is bonded in to the stock using a suitable epoxy adhesive. Two versions will be available; a flush version for deeper flat bottomed stocks and a radiused version which can be semi recessed for shallower or narrow curved stocks.
