The BOLT FACE TRUING TOOLS by MANSON PRECISION are designed to square and concentrically align the bolt face to the boltway using only hand tools.
It is specifically made for Remington 700 receivers and requires the use of a Tooling Block and one Facing Burr for operation.
The tool saves time by eliminating the need for extensive man hours and setup, and can be used with a slow speed drill motor after bolt lapping and squaring the receiver face.
