The photo shows an in the white (un-blued) part.

These milled Grip Mounts have been made in accordance with the A/O Colt print of 1921 and are of quality worthy of any TSMG made. They are through hardened carbon steel and are set apart from many made since (even some military) by having the proper, specified “bend” required to position them against the barrel providing the desired support and resistance to flexure. It should be noted that many of the mil-surp parts seen recently were overheated in the stripping process (when the receiver nose was torched to remove the barrel) and have lost their temper, making them prone to bending.
Finish is matte blue, (suitable for all military guns and others with a duller finish), or matte blue with a polished tongue (suitable for the Colts and other guns with a higher finish)
