Price is indicated for 1 piece.

90% of WW2-era produced M1 Garand had rear sight knobs with Lockbars.

The Lockbar was developed to replace the early Flush Nut type sight, and did not require the use of a tool to tighten and lock the rear sight in position.

There were 3 types of Lockbars developed during WW2. The first variants (Type I & Type II) had rounded edges. The third variant (Type III) simplified the Lockbar by eliminating the curved ends as an expedient to production.
